Estuaries :- 



2. The difference between the weight of the fish at the mouth and in 

 the upper waters of the rivers is practically nil in May and June, but 

 as the season advances the weight of the fish in the upper reaches 

 becomes less than that of fish in the lower reaches. 



In May and June there is a difference of only 3 per cent. In July 

 and August the estuary fish are 19 per cent heavier than the upper- 

 water fish, and in October and November 16 per cent, heavier.
