Growth and Immunity in Aquaculture
Shyam Narayan Labh, Shubha Ratna Shakya and Babita Labh Kayastha
Today we live in a world where poverty, hunger and malnutrition are prevalent. It has been estimated that 14 per cent of the global population or 852 million people are going hungry and of these 690 million are in the Asia-Pacific region. Aquaculture is the farming of aquatic organisms in both coastal and inland areas involving interventions in the rearing process to enhance production. It is probably the fastest growing food-producing sector and now accounts for 50 percent of the world's fish that is used for food. Fish contributes over 20 per cent of the animal protein intake for more than 2.6 billion people around the world. Hence, fish and fisheries make a major contribution to nutritional security and the fight against hunger and poverty in Asia. Immunostimulants known as immunostimulators are attractive substances that activate the immune system of humans and animals for prevention of diseases and improvement of the body's natural resistance to various viral and bacterial infections. These biologically active substances are the products derived from natural sources or synthetically made with different chemical properties and mechanisms of action. Lapsi, Choerospondias axillaris is indigenous fruit tree of Nepal found growing within 900- 2000 m above sea level in many parts of the country. Native to Nepal hills (850-1900 m asl), the tree has also been reported from India, China, Thailand, Japan and Vietnam. Nepal is unique for processing and use of Lapsi fruits. Fruits are rich in vitamin C content, and are consumed fresh, pickled and processed for preparing a variety of sweet and sour, tasty food products locally called as Mada and candy. It is grown in 301 village Development committees of 29 hill districts of Nepal for some socio-economic purpose. Like other medicinal fruits, lapsi also act as immunostimulants and enhance the immunity of fish during aquaculture.

|5 Species Diversity of Indian Aphids (Hemiptera: Aphididae), Rajendra Singh and Garima Singh
The aphids are tiny sap sucking plant lice that not only infest agricultural and horticultural crops but also spread several viral diseases. They are very fascinating insects as these are thelytokous parthenogenetic viviparous, having short generation time and telescopic generation with polymorphism. Many species of aphids display complex life cycles with alternation of sexual and asexual generations and host plant alternation. Aphids are almost cosmopolitan in distribution, but are most common in temperate areas. Unlike many taxa, aphid species diversity is much lower in the tropics than in the temperate zones. They can migrate great distances, mainly through passive dispersal by winds. At present all true aphids belong to a single family Aphididae which consists of 24 subfamilies. Globally, 5109 species of aphids are described under 527 genera. In India, 794 species of aphids under 208 genera are reported out of which about 385 are endemic.The subfamily Aphidinae constitutes a monophyletic group within the family with about 3100 extant species worldwide with higher diversity in temperate regions. In India, 431 species under 105 genera of this subfamily are reported out of which 192 species are endemic. In this paper, distribution of extant aphid species in different taxa of Aphididae is described.

|7 Allelochemical Stress, ROS and Plant Defence System, Deepmala Singh
In nature plants grow close to each other, hence there must be a competition arises between them for nutrition and space. For their survival plants must have some strategy to defense and attack. Plants produce various secondary metabolites which may not be of nutritional values and have toxic effects. These metabolites when released out of plants and come in contact with another plant, exerts some effects (deleterious or beneficial) on recipient plant. These metabolites are known as allelochemicals or allelopathins. Allelochemicals also serve as defense agent against herbivores or competing plants due to their toxic nature. They maybe used as a toolfor attack. They exert biotic stress which is called as allelochemical stress or allelopathy. Present study investigates the adverse impact of allelopathy on recipient plant with special reference to production of ROS, oxidative stress and defense enzyme system.

with marketing and economic condition of the
Fishers and related collectors, B.K. Chakraborty, M.H. Shahroz, A.B. Bhuiyan, S. Bhattacharjee and S. Chattoraj
The spawn of Indian major carps makes the Halda River an irreplaceable heritage of Bangladesh. The study was conducted to observe present status of Indian major carp breeding and collection management procedures of carp spawn and fry from the Halda River along with marketing process and economic conditions of the fishers and spawn collector. Data were collected through direct interview. In marketing system of carp eggs, spawn and fry in the Halda River, a number of intermediaries were involved actively in the marketing system. Four different types of marketing systems were identified in Halda spawn and fry distribution fry seller to final consumer. Fertilized eggs and spawn were collected and hatched by the local fisher's and collectors using their indigenous method. Those egg collectors sold to the hatchery owners per kg spawn at the rate of 50,000-80,000 BdTk. Again hatchery owners sold each and every fry at the rate of 5.0-6.0 BDTk. to the local fish farmers. Yearly survey information on Halda River's egg, spawn and fry collection showed an ups and downs production rate during last 07 years. The production status in the year 2011, 2012, 2013, 2014, 2015, 2016 and 2017 was 230, 1569, 526, 508, 107, 320 and 338kg respectively and these types of ups and downs indicated poor number of broods, poor breeding ground and poor ecosystem of the Halda River. Different types of transports were used to carry fertilized eggs and spawn of Halda River. Investigation was also done to find out the economic condition, average income during breeding season and off season, educational background and family status of the local people of Halda region involving in fry collecting and marketing system. The study recommends that ecosystem health and breeding ground of Halda River should be protected for ensuring availability of pure line fertilized eggs and spawn of Indian major carp.
|10 Diversity of Parthenium hysterophorus and
associated weeds in the Chitrakoot District, Preeti Tripathi and Ramesh Chandra
Parthenium hysterophorus L. (Carrot grass) is an annual herb of neotropical origin that now has a serious problem and pantropical distribution. It was first reported in India in 1950 at Pune (Maharashtra). This weed is very aggressive and commonly known as Congress grass and carrot grass in India. It has achieved major weed status in India within a relatively short period of time. P. hysterophorus is grown mostly in cultivated fields, fallow lands, pasture and along the roadsides. To analyse the distribution of this weed in Chitrakoot district an exhaustive survey was performed in the holly place of Uttar Pradesh like Rajapur, Pahadi, Karwi and M.G.C.G.V. campus. During survey, the distribution of P. hysterophorus was measured in the agricultural lands, road side, river side and fallow lands. Moreover, the study also investigated the harmful effect of Parthenium upon native weeds and flora in the Chitrakoot district. Quadrates method (1mx1m) was used to collect the data of distribution and population of this weed. In this investigation, total 14 weed species were recorded belonging to 8 different families and 14 genera. The data were recorded by Absolute density (m2), relative density (%), absolute frequency (%), relative frequency (%) and importance value (%) of Parthenium and other associated weeds. The finding reveals that Parthenium weed is the most dominant species in comparison to other associated weeds. In conclusion, the Parthenium weed become a serious problem and replaces the entire native flora in the non-crop area. Due to no proper management and high growth rate, nowadays it becomes as super weed in the Chitrakoot district. So, the management of Parthenium weed requires the call attention from the Government Policy makers and proper quarantine inspection to conserve the native flora and fields crops to get maximum crop yield.

|13 Alternative Methods Replacing Animal
Testing in Research: An Overview, Abhishek Singh and Preeti Singh
The discovery of new drugs involves their testing on animals for efficacy as well as safety before the approval. Millions of animals are being sacrificed to fulfill this need. But experimentation on animals during the past years has created a matter of attention to the Institutional Animal Care and Use Committee (IACUC) for better care and handling of animals. The main aim of these committees is to reduce and finally exclude the animal use from the area of research with appropriate alternatives. Various alternative methods and organisms have been implemented and used respectively in this aspect in the last few years. Alternatives of animals serve the same purpose as that of utilizing whole animal for testing. The techniques such as in vitro method, computer model, stem cell, alternative organisms, use of biotechnology etc. might eventually replace the use of animals for testing and these approaches may provide an insight to minimum utilization of animals in s cientific research. Some alternatives of animal testing have been discussed in this article with some examples.

|23 DECLINE OF HOUSE SPARROW AND COMMON
MYNA POPULATION IN DODA REGION OF
JAMMU AND KASHMIR, INDIA, Wahied Khawar Balwan and Neelam Saba
The House Sparrow (Passer domesticus) and Common Myna (Acridotheres tristis), once very common birds, have declined markedly in most parts of the India including Doda district of Jammu and Kashmir. Once these birds were distributed widely in Doda district but over the past few years, they became not so common in this region. A study has been conducted during April 2016 to April 2020 to establish the database for their current population and to assess the possible causes of their decline in Doda district. The house sparrow is a symbiotic bird species highly adaptable with human habitation. House construction due to modern trend has resulted in reduced safe nesting for sparrows and mynas. Green spaces in our cities give way to more concrete construction due to which the house sparrow and myna loses its foraging ground. There is a dire need of ecological balancing to save the Sparrows and Mynas from getting extinct.

Amar Chandra Mandal and Om Prakash Singh
A survey was conducted during December 2019 to March 2020 in the Siraha district of Nepal to assess farmers' perception on climate change and identifications of local practices to maintain the yield of rice production. Total 60 samples were purposively selected from the study site. During interaction and interview, the opinion of 75- 80% formers was that temperature increases, rainfall duration and its frequency decreases due to the global warming. About 33.33% farmers experience was an increase in flooding hazard due to increase in rainfall intensity during the rainy season in Siraha and its vicinity. The majority of respondents perceived increased in weed and pest (65%) and new weed (30%) and new pest (26.7%) infestation due to climate change. About 18% respondents had a clear knowledge of climate change. The major source of information was selfexperiences (80%) and organization (20%). The major climate change adaptation practices adopted by farmers were the use of drought-resistant varieties (11.67%), flood-resistant varieties (13.33%) and early maturing crops (15%). Crop insurance is one of the adaptation practices to climate change. The study showed that 63.33 % of the respondents know about crop insurance policy but none of the respondents have done crop insurance on different crops. The increase in disease and pest infestation is major problems of farmers. The focus group discussion and key informant study showed that the farmers were positive to adopt climate change adaptation strategies. So, Government and policymakers should focus on climate-resilient adaptation strategies formulation for rice cultivation through intensive research and extension package. Adoption of different resistant varieties and technological adoption like zero tillage, application of irrigation, and training related to adoption techniques should be done.

TUMOR SUPPRESSOR GENES DUE TO NATURAL
COMPOUNDS IN BREAST CANCER CELLS, Debasray Saha, Neeraj Vaishnav, Zubiya Ahsan, Nisha Rani,Runjhun Mathur and Abhimanyu Kumar Jha
Breast oncogenesis is a multistage process that involves epigenetic and genetic changes. Epigenetics is outlined as reversible changes in gene expression, with no alteration in gene sequence. DNA methylation, histone modification, and nucleosome transformation are the foremost epigenetic changes that may get dysregulated in breast cancer. Epigenetic silencing of tumor suppressor genes (TSGs) is reversed by varied molecules as well as natural compounds like polyphenols which will act as a hypermethylation agent. Nowadays, much of the research is going in the direction of natural and dietary compounds and attempting to search out novel and extra effective medical aid for the breast cancer patients. In this literature, few vital natural chemical compounds effective against the breast oncogenesis with their mode of actions are discussed. Such chemicals act as an analytical and prognostic tool in breast cancer due to their role in epigenetic regulation.

THIRUVANNAMALAI (TAMILNADU), INDIA, E. Sugumaran, B. Shabeena and M.V. Radhakrishnan
The present investigation was an attempt to study the zooplankton community of Sathanur reservoir of Thiruvannamalai, Tamilnadu, India. The zooplankton species composition was studied for a period of one year from October 2018 to September 2019 on monthly interval basis. As a result of study, 24 zooplankton species were identified, out of which 9 were Rotifers, 7 Cladocerans, 5 Copepods and 3 Ostracodans. The overall population density of zooplankton was found maximum during the summer season and mininmum during monsoon. They play a supportive role in fish culture by recycling of nutrients and increase the soil fertility and involve in energy transfer between phytoplankton and fishes.
|34 TOXIC EFFECTS OF PAPER MILL EFFLUENTS ON MORTALITY,
BEHAVIOUR AND MORPHOLOGY OF SNAKE HEADED FISH,
CHANNA PUNCTATUS (BLOCH.), Sadguru Prakash and Ashok Kumar Verma
Present study was undertaken to find out the physico-chemical characteristics of paper mill effluents and their impact on mortality, behavior and morphology of fish, Channa punctatus. The result of physico-chemical characteristics of treated effluents showed that pH, EC, chloride and phenolic compound are within the permissible limit but colour, order, BOD, COD, TSS do not meet the permissible standards set by Central Pollution Control Board of India. LC values of paper mill 50 effluents of both sites (Po and Pd) for Channa punctatus were found 15% and 20%, respectively after 96 hours. Authors recorded abnormal behaviour of the fish studied throughout 96 hours in both effluents. The fishes showed erratic, haphazard movement, rapid opercular movement and tendency to jump out of water. The effluent exposed fishes showed the excessive secretion of the mucus. Many changes were seen in gill, skin and fins of fishes due to exposure of effluent. The gill colour changes from dark red to dull red and skin become erupted. The response of the fish towards toxicity was grossly dependent on concentration of effluents and length of exposure. Thus, the present study revealed that fish, Channa punctatus is sensitive to paper mill effluent toxicity and can be used as biological indicator.
|35 EVALUATION OF ANTIOXIDANT ACITIVITY OF EISENIA FETIDA, Pinky Deswal, Yasha Yadav, Khushbu and Vineeta Shukla
Antioxidant assay was performed to count the total phenolic content in coelomic fluid of Eisenia fetida. The worms were cultured in lab until they became sexually mature. The study focused on total phenolic compound determination using two solvents in a single species of earthworm. It was analysed that the extraction of phenolic compound with 85% ethanol yielded high phenol content, 208.6 mg GAE\L Eisenia fetida. Extraction with 85% methanol on the other hand, yielded 189.1 mg GAE\L. Eisenia fetida ethanolic extract in the sample manifested high total phenolic content than methanolic extract. Phenols are more readily soluble in ethanol and safe for human consumption. Methanol is used as solvent for low molecular weight polyphenols. The study concludes that ethanol extract of Eisenia fetida coelomic fluid contains significant amount of phenols. Phenols have an antioxidant effect and can be used as natural antioxidants for curing ailments related with inflammation and oxidative stress. This study will help in bringing attention towards the therapeutic utility of earthworms.

|41 STATUS OF ANIMAL PHYLA IN DIFFERENT KINGDOM
SYSTEMS OF BIOLOGICAL CLASSIFICATION, Ashok Kumar Verma and Sadguru Prakash
Biological classification is the scientific procedure of arranging the organisms in a hierarchical series of groups and sub-groups on the basis of their similarities and dissimilarities. Many biologists have contributed to this method of classification, which took years for researchers to decide the most fundamental characteristics for the classification. The history of kingdom system in classification is started with Linnaeus (1735), who laid the foundation of modern biological classification by classifying the organisms into two kingdoms namely Plantae and Animalia. The two kingdom system was followed by three, four, five and six kingdom systems respectively. In present discussion, authors tried to discuss the current status of different animal phyla with respect to different kingdom systems.

|49 MYIASIS, DIPTERAN FLIES AND THEIR IMPLICATIONS
IN FORENSIC ENTOMOLOGY, Sunita Rawat
Myiasis is a pathological condition caused by the larval infestation in human or animal tissues. It is caused by the larvae of dipteran flies which are cosmopolitan in distribution. It occurs frequently in tropical countries and developed due to poor hygienic conditions. In human beings, the most commonly affected sites are the skin, mouth, ears, eyes, nose, anus and vagina. The diagnosis of the disease includes examining the larvae in the wounds and lesions. Pain and irritation in the affected body parts are the general complaints by the patients. The treatment is generally carried out by local disinfection and removal of larvae from the affected area. Effective fly control measures and good hygienic conditions should be adopted to control the disease. Insect life cycle stages found on the body and crime scene may be used in the estimation of post-mortem intervals (time since death) in forensic investigations. Insect evidence can also be used in the conditions of myiasis in living beings. Neglect or cruelty results in the untreated wound, and accumulation of faeces or urine, therefore attract the flies to oviposit. These eggs, larvae, etc. can be collected from the wound and presented in the court of law. A forensic entomologist can determine the minimum time since abuse or the duration of neglect by estimating the temperature, species, and age of the insect.
|50 APPLYING SINGLE VERSUS MULTIPLE METHODS FOR
DELINEATION OF FISH STOCKS WITH SPECIAL
REFERENCE TO MORPHOLOGICAL TOOLS, Deepmala Gupta and Madhu Tripathi
Stock identification methods have been developed with the progression of technology but this sometimes brings problems rather than the solution since the advancement in methods is not unidirectional but diffused. As of now, every method has pros and cons. The choice of the best method of population/stock discrimination is a critical issue depends on the frame of the study and the desired objectives to be fulfilled. The best method(s) would be the one which is rapid, reliable, low cost and easily applicable. In this article, the focus is given to morphological approaches. Since long, body morphology, as an efficient tool, has been used to delineate fish stocks, which contributes to the conservation management of important fauna. In stock or population delineation studies of fishes, landmark-based quantitative shape analysis of the organism body have a valuable role to play and complementing other existing approaches. Nevertheless, there is no single best method which can be applied to all or any species for their identification/delineation. The best method varies from species to species as does the requirement to one or more methods and even employing more than one discipline.
