The present study was conducted in a pond of Saharsa district of Bihar during April 2018 to June 2019.  The physico-chemical and the biological parameters were analyzed by using standard methods. The parameters considered were Colour, Odour, Temperature, pH, Turbidity, EC, TDS, TA, TH, Mg2+ hardness, Ca2+ hardness, Nitrate,Phosphate, DO, BOD and Chloride.

During the study the colour and the odour of the water bodies were recorded as normal one. Temperature was 320C- 10°C . the pH was recorded 6.9-8.6 during the study period. Turbidity found 20 NTU -1.2 NTU. The EC was high in the winter and low during the summer. TDS recorded high at site 1 and site 2 during monsoon season. At some site TDS values recorded high 1445 mg/I during the summer also. The minimum TDS was recorded as 342.4 mg/I at site 1 during the winter. Total Alkalinity was recorded high (360 mg/I) during winter at site 4 and minimum was recorded during monsoon at site 2. Dissolved Oxygen recorded maximum 12.47 at site 2 and the minimum 0 at site 4. There was sewage water and other effluents released into the pond t site 4, which may be one of the reason forgetting zero value of DO.

BOD also recorded high at site 4. Among biological parameters phytoplankton and zooplankton were counted by using Sedwitch rafter chamber. The total count per ml and per liter was calculated for all the four sites. There are total 33 plankton species per ml were recorded. Out of this 27 were phytoplankton while rest zooplankton species. Among phytoplankton Chlorophyceae were more abundant during monsoon season while Bascillariophyceae were recorded maximum during the summer and winter season. Plankton (both phytoplankton and zooplankton) shows correlation either positive or negative with physico-chemical parameters especially against temperature, pH, Turbidity, Total hardness, Total Alkalinity, DO, BOD and Nitrates. The site 3 and the site 4 shows some signs of eutrophication.

Fish culture is an important enterprise especially in the Kosi region of Bihar. In the present investigation, a survey has been made in three districts of the Kosi region to find out the adoption of fish farming recommendations to the farmers. It has been found that the literacy rate among fish farmers in the region is 41.6% and 73.3% of farmers are trained in fish farming. The average pond size is 0.37 ha and 56.6% ponds are perineal. About 70% ponds are older than 15 years, 46.6% fish farmers prepare their pond before stocking,40% farmers remove unwanted plants before stocking the pond 46.6% farmers use organic manure in the pond and 40% use lime and 46.6% use inorganic fertilizers while stocking the pond,23.3% farmers stocks the pond with spawn and 30% farmers uses three fish species in the pond. Before stocking the seeds about 70% farmers treat the seed fordiseases.20% farmers feed the fishes with formulated feed as supplementary feeding. 93% of farmers feed their fishes for more than six months, 96% farmers contact to Department of Fisheries in case of adverse conditions observed during the culture period.

http://anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2020/06/8-JUNE-2020.pdf

·

  This study was taken to establish the existence of Cybister confusus beetles collected from four ponds located at different villages in Madhepura district (Bihar). The growth performance of beetles has been related to acidity (pH) and salinity (%). Distribution and abundance of beetles may probably be dependent upon water pH which is 5.6 to 6.2. They also show oligohaline in nature.

Physico-chemical and bacteriological analysis study is important to assess the acceptability of drinking water quality. The water samples of ten tube wells and ten open wells were collected from five different villages of Supaul district, Bihar for the study of physical, chemical and bacteriological characteristics of the water samples. The results revealed that the pH varied from 6.5 to 7.0, the electrical conductivity 415-490 pS/cm, carbon dioxide ranged from 4.8-7.8 ppm the total alkalinity ranged from 152­190 ppm total hardness 140-182 ppm dissolved oxygen 1.2-4.2 ppm ,BOD 1.2 -4.8 ppm and COD 38.0­68.0 ppm About 40% tube-wells were found to be polluted with FC (Faecal coliform bacteria) while those for 80% with TC (Total coliform bacteria). All the open wells were infected with FC and TC. The concentrations of testing parameter in the drinking water samples were beyond the permissible limit of the WHO and BIS. In this investigation it has been found that location of latrine,drain,bird’s excreta and sewerage line near tube wells and open wells are more likely the reason of contamination of water with both FC and TC. This maybe a major public health issue, and needs immediate attention forremedeal measures.

 Fish are the most numerous group of vertebrates in the world. This article is aimed to present the volumetric study of air-bladder in a local fish- Bata, scientifically known as Labeo bata (Hamilton, 1822). The study was performed by anatomical dissection of184 fishes of Bata species with further macroscopic examination of air-bladders. The research showed that in investigated species this organ has significant differences and is composed of two chambers. The present study assesses air-bladder dynamics in natural occurring populations with the aim to examine volumetric relationship between air-bladder and body of the individuals. It is clear that the buoyancy provided by the air-bladder. Air-bladder volume is a mean 9.4% of fishbody volume. Evidence is given to indicate that this is quite large when compared with data ‘5% of fish volume for marine fish, and 7% for freshwater fish.

 The population growth of Cybister confusus, an aquatic insect in a pond was studied with emphasis on water temperature. Population of the Cybister confusus was examined in relation to temperature. This measure accounts for time and the minimum temperature necessary for insect growth and reproduction to enhance population size. Result showed highest population density at about 17.6 °C temperature. Studies demonstrated that the population of insects is directly proportional to change in seasonal temperature cycle.

·

 In the present work an attempt has been made to study the effect of few hormones and pharmacological drugs on changes in proximate composition in whole body in a fresh water air breathing murrel, Channa marulius (Ham.). The water, protein, lipid and carbohydrate + ash content of the fish body (50.0±1.5g) of control group of fishes were 74.79±0.19, 16.02±0.32, 3.21±0.11 and 5.98±0.43% respectively. The treatment of Hydrocortisome and Durabolin brought decrease in water content but increase in protein and lipid content as compared to control. While the treatment of L-thyroxine brought an increase in water content but decrease in protein and lipid content. The details have been discussed in this fish.

 Studies on seasonal variations in proximate composition have been made in a teleostean air breathing fish, Channa marulius(Ham.) in relation to ambient water temperature. Minimum values of percent water, protein, lipid, carbohydrate content and calorific values (K.cal/g) were recorded in the months of November, March, August, June and February respectively while maximum values of above noted parameters were recorded respectively in the months of July/August, June, December, May and June. The statistical relationships between ambient water temperature Vs. proximate composition fractions 0 0 were established by two separate regression lines one between 18.5 to 29.0 C and another between 29.0 C 0 to 33.4 C. The details have been discussed in this paper.

·

Aquatic macroinvertebrates, which play a significant role in the food chain of an ecosystem, are used in freshwater quality assessment to identify the environmental stress resulting from a variety of anthropogenic disturbances. Samples survey of macroinvertebrate communities were conducted from April 2016 to March 2017 in ox-bow wetland (Kawar lake) of Begusarai district (Bihar). Altogether 74 species (7 species of Annelida, 56 species of Arthropods and 11 species of Mollusca) of macroinvertebrates were recorded from the studied sites during the investigation. In present paper we analyse the qualitative and quantitative abundance of macroinvertebrates (annelids, insects and molluscs) of Kawar lake ecosystem.

The physico-chemical parameters of Kosi river near Koparia, Saharsa, Bihar have been studied monthly during July 2014 to June 2015 from two sites. The results revealed that there was significant seasonal variation in some physico-chemical parameters and most of the parameters are in the normal range indicating better quality water resources
