Shrimp Trawl Fishing Experiment on the Fishing Comparison between Mexican Net and Commercial Net Type

Abstract

The next five years plan (1972-1976) of the fisheries development project, one of the aim to increasing the shrimp production for the local consumption and export, the project should be carried out the two items as follows: 1. To harvest the shrimp form natural water by improving the fishing gear 2. Shrimp farming According to the fisheries census of the Fisheries Department in the year of 1967 the number of shrimp beam trawl fisheries consists of about 424 units, 75 percent of which are small size of boat (less than 10 tons) and also small size of net. The Fisheries Department Contemplate to improve the shrimp trawl fisheries on it’s gear to be advance and expect the catch of more shrimp (follow item1). The Fisheries Department, therefore, request fishing gear expert from Southeast Asian Fisheries Department Center (SEAFDEC) for joining shrimp trawl fishing experiment. Thus, the main purpose of this experiment are to find rational and effective shrimp trawl net design operating both in the Gulf of Thailand and Indian Ocean for commercial fishing vessel , to make simplify the construction of net for the fishermen use and to define the optimum size of net relatively with the size of horse power of vessel engine.
