Future Production

Jammu and Kashmir serves a congenial habitat for variety of fish species due to large number of cold water resources which has paved way for the development of fisheries sector in the state. The state has crossed 20.0 thousand tonnes of fish production because of modern aquacultural practices implied at both governmental and private levels. Kashmir province is a leading producer of fishes contributing more than 80% of the total production of the state while as Jammu on the other hand has also emerged as a major producer of animal protein through fisheries sector. The fish production data of four decades reflects increasing trend of production in all commercially important species of both the provinces. However the statistical models forecasting the future production provide an idea about the growth patterns in fishes. In this paper, growth pattern of three different fish species (Trout, Mirror carp and Country fish) from Kashmir province and various fishes from Jammu province (collectively named as Jammu fish) of the state was assessed using fish production data from 1956-57 to 2011-12. Forecasting of fish production was made on the basis of the best fitted statistical models. Results showed that Kashmir province shows overall compound growth of 4.2% against 7.9% of increased compound growth rate of fish production of Jammu province since 1956-57. Cubic model was found to be the best fitted model for all the species in both the regions. However, when future fish production of the state is taken into consideration, the statistical models indicated a decreasing trend in the overall fish production of both the provinces. Besides, the matter of concern is that the demand of 70,000 thousand tonne consumption of fish protein in the state which is a milestone yet to be achieved.

Chlorine Toxicity

The avoidance response of selected cold-water (stenothermal) and warmwater (eurythermal) fish species to total residual chlorine (TRC) was found to be species specific, influenced by temperature, and dependent upon the constituents within the TRC. The first significant avoidance of TRC (primarily free chlorine) at 12 and 18 °C occurred at concentrations ranging from 0.05 to 0.10 mg/L for salmonids — rainbow trout (Salmo gairdneri), and coho salmon (Oncorhynchus kisutch) — and 0.10 to 0.40 mg/L at 12 and 24 °C for the eurythermal species — largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus), and mosquitofish (Gambusia affinis). A greater concentration of TRC was necessary to initiate avoidance at the highest acclimation temperature for most fish species tested although the amount of hypochlorous acid (HOCl) within the TRC was approximately the same regardless of the acclimation temperature at each avoidance concentration. For exposures comprised mainly of monochloramine (MONOCl), initial avoidance concentrations were generally equal to or greater than concentrations avoided in the TRC trials. After attraction into heated water, bluegill and largemouth bass avoided some TRC or MONOCl concentrations which were either equal to or twofold greater than the concentrations determined in tests without temperature attraction; for mosquitofish, the differences were as much as three to four times greater. Temperature attraction into chlorinated water was less influential for salmonids in elevating the avoidance response of chlorine with only a twofold increase in the avoidance concentration of TRC and none for MONOCl.Key words: chlorine avoidance, chlorine toxicity, temperature selection, stenothermal fish, eurythermal fish

The article touches upon the problem of the rational use of fish stocks in fishing water bodies, which implies using modern accounting methods for fish abundance and fish stocks. To this end, instrumental surveys are carried out. In the fishing rivers of Kazakhstan (the Zhayik and Kigash Rivers) there was previously used the biostatistical method of accounting based on data from fishing statistics. The statistical data have recently become unreliable, since they do not take into account the illegal, unregulated and unreported catch. Instead of the biostatistical method, it has been proposed to use the time-based method which considers the fish that have passed along the river for a certain period of time and extrapolating these data for the entire duration of the fish run. The results of using the method to estimate the abundance of semi-anadromous fish species in the Zhaiyk River in the spring of 2019 are shown. There has been developed the method determining the catchability of a commercial seine on the river by conducting simultaneous fishing with two seines following one after another. For each fish species in the catch, the catch coefficient should be calculated separately. Examples of calculating the abundance, ichthyomass, and commercial stocks of various fish species (roach, sazan, bream, asp, crucian carp, sabrefish, catfish) that entered the river in the spring of 2019 are presented. There is found a difference in the values of the commercial fish stocks determined by the time-based and biostatistical methods, due to the lack of the subjective component of the forecast.
