Abstract

Studies on properties of the netting material form a prelude to the applicability of mateial to different types of fishing gears. Weathering of nylon is mainly due to the effect of ultraviolet rays. The effect of insolation on nylon netting yams of 9 different specifications (210Dxlx3 - 210Dx24x3) over a period of 150 days was studied by measurement of loss in breaking strength. A common regression line for percentage retention of breaking strength (Y) vs. period of exposure (X) of nylon netting yams was fitted (Y = 99.6 - 0.276X), irrespective of specifications, based on results of Bartlett's test and analysis of co-variance.
