Studies on the effect of different pesticides and their combinations at 48 and 96 hour exposure on water (Moisture), protein content and calorific values in a fresh water teleostean fish, Mystus vittatus (Bloch) has been made. The treatment of Kelthane (an organochlorine), Metacid 50 (an organophosphate pesticide) and Dithane M-45 (a carbamate pesticide) increased the water content in M. vittatus, though the effect was more pronounced at 96 hr exposure as compared to 48 hrs exposure. The treatment of pesticides brought significant decrease in protein content and calorific values (k/cal/g), the maximum decrease was observed after the treatment of Metacid at 8.0 ppm after 96 hrs exposure. The details have been discussed in this paper.

Studies on the effect of some exogenous hormones and drugs on haematological indices were made in a freshwater air breathing snake headed murrel fish, Channa punctatus (Bloch). The treatment of ACTH, adrenaline, phentolamine, growth hormone (GH), T4, T3 and methyl testosterone brought about significant increase (P<0.05) in TEC (total erythrocyte counts), Hb content, PCV values and oxygen capacity as compared to control. The MCHC, MCV and SAE (Surface area of erythrocytes) showed drecreasing trends while thiouracil failed to after these indices to a significant level.

·

In the present study an attempt has been made to study the inter-relationship, if any, between cyclic changes in the activties of adrenocortical tissues and oxygen consumption in the fresh water fish, Mystus tengara (Ham.). A positive correlation occurred between mean nuclear diameter (MND) of the interrenal tissues and oxygen consumption (VO2) in Mystus tengara (Ham.). In both the sexes minimum MND and VO2 were observed in December- January while the maximum values for these parameters were recorded in June. The injection of hydrocortisons brings about highly significant increase in VO2 while treatment of adrenaline brings about significant decrease in VO2 in this fish.

In the present study an attempt has been made to assess biochemical composition of ten species of fresh water teleostean fishes, with a view to know their relative nutritional values. Heeropneustes fossils (BO had higher values of protein and other components while Pangasius pangasius (Ham.) had more lipid as compared to other fishes.

ASSESSMENT OF CONCENTRATION OF HEAVY METALS IN DIFFERENT BREEDS OF POULTRY MEAT IN KARNATAKA

Metals such as iron, copper, zinc and manganese, are essential metals as they play important role in biological systems for normal physiology. But the same metals can become lethal when consumed above the threshold level. Others, such as lead and mercury are non-essential and highly toxic even at very low concentrations. Excess amount of metals uptake by animals find their way to human body and are very harmful. High demand for excessive production of poultry meat has led to the extensive modifications of poultry feeds in the recent years. Usage of chemicals in profit making poultry business is drawing the attention of consumers. So the results of the study conducted to assess the residues of heavy metals in poultry meat showed no much difference between breeds and the values are within permissible limit.

SEASONAL AND DIURNAL VARIATIONS OF PRIMARY PRODUCTIVITY IN SUNDERDAM RESERVOIR OF GODDA DISTRICT (SANTAL PARGANA), JHARKHAND

Studies and diurnal variations of primary productivity in Sunderdam reservoir was conducted to evaluate the productive potentiality and the nature of community metabolism in the reservoir. Remarkable high values of gross and net productivity was recorded during winter months while minimum values in monsoon month. Abiotic factors like light intensity, water temperature, nutrients (Phosphate, Silicate and Nitrate) and biotic factors like phytoplankton density etc. influenced the productivity values. Production and Respiration (P/R) ratio was evaluated more than one (P/R >1), which referred to autotrophic nature of the reservoir. Besides, Net Daily Metabolism (NDM) revealed positive value in different seasons (0.169 —0.307) confirmed the community metabolism was dominated by production and emphasized the importance of autochthonous input to the reservoir.

The use of pesticides rises exponentially with the industrial and agricultural development. However, these pesticides create serious threat to the non-target organisms both in terrestrial as well as aquatic ecosystems. Hazardous chemicals from industrial wastes and agricultural runoff are the main causes of water pollution. An aquatic organism mainly fish accumulates many contaminants directly through their gills and skin and indirectly via their food chain, which may cause diverse alternations in their vital organs. In the present study, effect of pentachlorophenol (PCP) on the histology of testis of a freshwater catfish Heteropneustes fossils (H. fossilis) was studied by exposing the fish to sub lethal concentration at32pg/l/day (1/10 of LC50) for a period of 14 and 28 days. Histopathological changes were observed in testis which showed shrinkage of seminiferous lobules and vacuolization in the tubular epithelium as well as in interlobular space. Histological impairment in tissues of lobules was also observed during different periods of exposure, suggesting adverse impact of PCP on testis of H. fossils.

Poultry is one of the important sources of animal protein along with vitamins and minerals. As desi breed are slow growers, now superior breeds of chicken are reared for eggs and meat, using formulated feeds. Nutrient composition may vary between breed, gender, age, feed used and also differs according to the edible portion of the body. This study was done to determine the macro and micro nutrient levels in various tissues of different breeds of poultry meat. The results of the present study show difference in the amount of nutrients in various tissues of different breeds.

Water quality of the river Chenab, an important Himalayan tributary of the river Indus, was studied at Akhnoor and has been described. Temperature, depth, turbidity and BOD recorded winter low record. Transparency, conductivity, total dissolved solids, dissolved oxygen, bicarbonate, chloride, calcium, magnesium and total hardness remained comparatively high during winter. Carbonate, sodium and potassium observed winter increase during first year and low record during second year. pH, nitrate, sulphate and silicate observed winter low record during first year and high record during second year. Phosphate observed irregular record throughout the year. These physico-chemical parameters remained irregular during summer and monsoon season.

In the present work an attempts has been made to study the effect of L-thyroxine (T4) and Thiouracil (Tu) on somatic (S.G.R.) and linear growth rate (L.G.R.) in an air breathing freshwater siluroid fish, Heteropneustes fossils (Bloch). The treatment of L-thyroxine (at physiological dose) brought about significant increase both in somatic growth rate as well as linear growth rate while the effect of thiouracil was contrary to this. The details have been discussed in this paper.
