Title Effect of salinity stress on neurosecretory cells, protein and free amino acid content and rate of ammonia excretion of the prawn Penaeus indicus H Milne Edwards
 
Creator Diwan, A D
Baskaran, V
 
Subject Prawn and Prawn fisheries
 
Description Stress induced changes resulting from salinity exposure are sought in the neurosecretory cells of different
neuroendocrine centres, in protein and free amino acid content in haemolymph, muscle. and hepatopancreas, and
in rale of ammonia excretion in the prawn Penaeusindicus. Prawns acclimated to low saline medium (S . 10%0)
when uansferred to rugh saline medium (5 .. 4Q%.o) showed liule change in their neurosecrelOry cell histologY'.
However, protein and free amino acid content in haemolymph. muscle. and hepatopancreas increased considerably.
Simultaneously, the rate of ammonia excretion was reduced. Prawns acclimated 10 high salinity medium when
transferred 10 low salinity exhibited changes in the above parameters in reverse to those findings in the former
experiment. The probable reasons for such changes are discussed.
