Trimethylamine oxide was found in the muscle press juice of all salt water fish examined and in the anadromous fish Pomolobus pseudoharengus taken from the sea. Traces were found in Anguilla taken from salt water, but none in Anguilla from fresh water.

And Storage

Sockeye smolts, pink and chum fry, and pink and chum fingerlings (Oncorhynchus) were sequentially weighed and measured when alive and after death in water and after killing and storage in formalin up to 225 days. The fish shrank within 12 hours to 97% and by 30–40 days to 96% of live length. Further changes in length were not significant. These same relative changes were observed from fish of different sizes, and the values were not significantly different among groups preserved in formaldehyde solutions of fresh or sea water. In fresh water, fish gained weight while yet alive but under anaesthesia. In freshwater formalin, fish gained weight rapidly for 1 or 2 days, then lost weight at a decelerating rate to the time of last measurement. Fish killed and stored in salt water formalin lost weight for the first few days, then gained weight at a decelerating rate. Relative magnitudes and rates of change were inversely related to size of specimens contained in the sample. These changes had pronounced effects on relative condition factors which varied from 97 to 135% of live values depending upon size of fish, type of formalin and time in preservative.

Migratory Movements

The fact that the salmon comes from the sea and spawns in the river has induced the supposition that this fish ascends the river only for the purpose of spawning. That the supposition is not always justifiable seems, however, sufficiently shown by the fact that clean-run salmon with undeveloped reproductive organs may be found in fresh water during the spawning season, and indeed at any season of the year, and also by the fact that a spring run of fish is usual. “When we regard the head waters of many of our rivers as localities for the natural propagation of the salmon, we find, however, that, except at the spawning season, adult fish are never present. When, at the same time, we remark that the fish which ascend to those waters during the winter months are all sexually ripe, we may fairly conclude that the fish are impelled to migrate to those head waters for the express purpose of spawning.It has been said that the shads (Clupea allosa, and C. finta) and the sea lamprey (Petromyzon marinus) are examples of fishes which have a spawning habit analogous to that of the salmon, since they also ascend rivers for the purpose of propagating their species. Their habit is, however, more analogous to that of the comparatively few salmon which penetrate at once to head streams and tributaries, than to the fishes which inhabit the lower reaches of a salmon river. They ascend for a limited period only, and seek again the salt water whenever the operation of spawning is completed. They are marine fishes which spawn in fresh water. The common eel may be taken as an example of a fresh water fish which spawns in sea water.

Present paper deals with study of cestode parasites of genus Circumoncobothrium from fresh water fish Clarius batracus at Savitri river, (Dapoli) for the percentages of infection occurance during summer season,minimum during winter and tolarate during rainy season.The parasite mainly infected the intestine of host and fed on nutrients from digested food. It completed its life cycle in the intestine of host. By camparing different characters of it to identify that the species is new

The present investigation deals with the prevalence of infection of cestode, Pseudoinverta oraiensis19 parasitizing Clarias batrachus from Bundelkhand Region (U.P.) India. The studies were recorded from different sampling stations of Bundelkhand region of Uttar Pradesh. For this study 360 fresh water fish, Clarias batrachus were examined. The incidence of infection, monsoon season (17.50%) followed by winter season (20.00%) whereas high in summer season (30.00%).
