Effect of using time in small pelagic purse seine with two vessels (slerek) on breaking strength and mesh size change in Pengambengan Archipelago Fishing Port (PPN), Bali, Indonesia

Abstract

The bunt net of a small pelagic purse seine with two vessels (slerek) serves as a place for captured fish before being loaded onto the boat. Seine nets that are operated within a certain of long time can be weathering and deterioration of the material caused by aging and environmental factors. This study aims to analyze the effect and relationship of the use time of a bunt net with Multifilament polyamide (PA) material 210 D/12 mesh size ¾ inch on breaking strength and changes in mesh size. The methods used are observation, interview, literature study and documentation to be further analyzed using descriptive analysis and MANOVA. The results showed a decrease in the breaking strength value of the net by 38% while on the contrary, a 5% increase occurred in the change in mesh size. The analysis conducted shows the influence of usage time on breaking strength by 95.9% with a very strong not unidirectional relationship level of -0.977 and the influence of usage time on changes in mesh size by 99% with a correlation coefficient value of 0.985 which means the level of relationship is very strong and unidirectional.
