    PHYSIOLOGICAL DISTURBANCES IN COMMON CARP (Cyprinus carpio) AS AN INDICATOR OF POLLUTION STRESS

    The use of insecticides is being increasing in the recent years to control the pest in which only 1% of the pesticide applied hits the target pest while, the remaining 99% of the pesticide drifts into the environment contaminating soil, water and biota. This poses a constant threat to the non-target organisms especially to fishes, because pesticides are known to alter their behavioral pattern, growth, and physiology. One of the early symptoms of acute pesticide poisoning is failure of respiratory metabolism, reduction in the food consumption, alteration in absorption efficiency, scope for growth and oxygen: nitrogen ratios of fishes. A static renewal bioassay was conducted to determine the acute toxicity (LC50) of commercial grade Organophosphate insecticide, Quinalphos (25% emulsified concentration) to common carp (Cyprinus carpio). The acute toxicity of Quinalphos to carp fingerlings exposed for 96 h was found to be 2.75ppm. For sublethal toxicity study, the fishes were exposed to two sublethal concentrations (1/10th of LC50 i.e 0.275ppm and 1/5th of LC50 i.e 0.55ppm) with lethal concentration (2.75ppm) for up to 48 hours. The carps were found to be under stress but mortality was insignificant in both sublethal and lethal concentrations. Considerable variation in respiratory rate was observed in both sublethal and lethal concentrations. 84 The effects of this pesticide on the physiological condition were remarkable. Food consumption rate, absorption efficiency, scope for growth and Oxygen: Nitrogen ratio of the fishes was affected when it was exposed to increasing concentrations of Quinalphos. The observed alteration in physiological condition may be a consequence of impaired oxidative metabolism and elevated physiological stress by the fish against quinalphos stress.

    STUDIES ON BENTHIC DETRITAL AGGREGATE FORMATION IN CULTURED SHRIMP POND

    India is a vast country with having varied and enriched natural resources. The natural resources like freshwater, marine water and the brackish water are important in production and development of resources. India has huge potential brackish water resources and these brackish water resources include estuaries, coastal lagoons, mangrove swamps and coral reefs supports a varied biological resources, such as fishes, prawns/shrimps, crabs, mussels, (clams, cockles, and oysters), lobsters, and other with their seed resources as well as sea weeds. India has 1.30 million ha. brackish water area suitable for aquaculture. (Ghosh, 2010). Out of which, at present about 1.41 lac. ha. area is presently under aquaculture (traditional, improved extensive and semi-intensive systems). And the estuaries covered along North Kanara district are Kalinadi, Aghnashini and Sharavati. The mid 1980s to early 1990s was a period of rapid growth in the production of cultured shrimp, particularly in South East Asia and Central America. Overall global fish production was estimated to be 140 million tons during 2009. Aquaculture production has contributed to 36 million tons in 2002 and reached to 50.3 million tons in 2OO7.This indicated that 6.5% growth was recorded in aquaculture alone. Shrimp production from both capture and culture was accounted to be 6.6 MT in 2009. China, leading first in shrimp production with 2.7 MT, followed by India and Thailand. However, the shrimp aquaculture industry has received unprecedented criticism for unsustainable practices. This has included the discharge of pond waters of high nutrients load and contributed to high phytoplankton to cause eutrophication of coastal waterways, destruction of mangrove and wetland habitats and depletion of world fish stocks to make shrimp feed. 4'he continuation of unsustainable practices has the potential to significantly hamper production of shrimp. The future of the shrimp industry relies on the development of more sustainable and best management practices.

    IMMUNE RESPONSE IN SHEEP TO IMMUNIZATION WITH DNA ENCODING THE VARIABLE REGION OF ANTI-IDIOTYPIC ANTIBODY SPECIFIC FOR HN PROTEIN OF PESTE DES PETITS RUMINANTS VIRUS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2010-07) APSANA, R.; SHRIKRISHNA ISLOOR; M.S. SHAILA; D. RATHNAMMA; B. M. VEEREGOWDA
    The present work was undertaken to evaluate and compare the immune responses in sheep to a recombinant DNA vaccine coding for VH chain region of anti-idiotypic antibody against HN protein of PPR and conventional PPRV vaccine. Twenty four seronegative sheep to PPRV antibodies were subjected to vaccination trials. Recombinant DNA vaccine and conventional PPRV vaccine were administered on days 0 and 21. Humoral immune response in vaccinates was evaluated by indirect ELISA and Serum Neutralization Test (SNT). The present study revealed high antibody titres in conventional cell culture PPRV vaccinated groups than recombinant DNA vaccinated group. However, the serum samples were having neutralizing titer of ≥ 8 in both the groups. Indirect ELISA results showed significant difference between the recombinant DNA vaccinated group and control groups indicating the capability of recombinant DNA vaccine to elicit immune response in the total absence of antigen. The preliminary study carried out infer that recombinant vaccine against PPR can be successfully used for protecting sheep against PPR and further overcomes the handling of PPRV for production of conventional cell culture vaccine.

    RURAL COMMUNITY ORGANIZATION FOR STRENGTHENING THE LIVELIHOOD SECURITY OF GOAT FARMERS THROUGH STRATEGIC SUPPLEMENTATION OF MINERAL MIXTURE AND UREA MOLASSES MINERAL BLOCKS (UMMB)

    A participatory action research was designed to promote the goat rearers’ groups in study villages and to strengthen the livelihood security through strategic supplementation of mineral mixture and UMMB. The analysis of the social situation revealed that all the villages were lacking basic facilities, infrastructure and services. The dissatisfaction of the villagers about existing conditions and problems was given expression with the formation of goat rearers groups in each study villages. The importance was given to collective work and necessity of the groups was stressed. The members have gained social benefits like managerial skills, increased interpersonal contacts, improved relation and better understanding among themselves, problem solving through group discussion and group consensus, opportunity to develop leadership etc in addition to this villagers got the benefits of regular health camps and training programmes. The results of On-farm trial revealed that the gain in body weights and decreased mortality are significant after the supplementation with mineral mixture and UMMB. However, the twinning percentage showed non significant result. The assessment of farmers perception revealed that due to strategic supplementation the mortality in kids was decreased and the health status was improved, animals stopped eating abnormal things. The major constraint of this supplementation was non availability of the mineral mixture and UMMB in nearby places. Farmers reported that supplementation technology was economically feasible and farmers were ready to it in future.
