Experiments in Fishing with Shrimp Trawls- On the Standardization of Tickler Chain

Abstract

The communication deals with the results of experiments conducted off Gujarat coast for the standardisation of "Tickler chain'' for shrimp trawls. Of the short link chains made of 3.2 mm., 4.8 mm. and 6.2 mm. rods the second was observed to increase the yield of shrimp in the net and without in any way adversely affecting the performance of the gear. The chains used had no influence on the fish catch.
