Analysis of the construction and resistance of pelagic trawls for catching pilchard in the Adriatic based on the model test and underwater observations

Abstract

       The paper gives an analysis of the results of testing the construction and resistance of the pelagic trawl models designed for catching pilchard and other species of the small pelagic fish in the Adriatic. The tested models are made in four variants differing in the constructional ele­ments of the mouth of the gear, while the other parts of the tested nets were equal in construction. The tests were conducted by trawling the models by means of the mea­suring bridge on the catamaran and the research ship. During these tests the constructional and technical para­meters of the gear were determined and on this basis also the best constructions of the nets for catching pilchard were designed.
