Abstract

Sharks are kind of ETP biota (Endangered, Threatened, and Protected), and are generally caught as by catch during fishing operations. In addition, sharks are one of the biota that plays a role in the life cycle in coastal waters. The Electro Shield System (ESS) was a device with an electromagnetic wave source that the shark can detect and make it afraid. ESS can be applied to set gill net operation to prevent the shark from getting caught. The objective of the study was to analyze the ESS on shark catches during set gill net operations. The research method was experimental fishing, conducted in March-May 2017 in Bangka Belitung Islands, Indonesia. Design the study by comparing shark catches during set gill net operation between those without using ESS (control) and using ESS with frequency 55 Hz. The shark catch by using Electro Shield System was 5.26% lower than control (7.80%). T-studentanalysis (sign 0.05) indicates that there was a significant difference between the set gill netwithout ESS and using the ESS against shark biota as bycatch. This indicates that the application of ESS in set gill net can reduce the capture of shark as by catch
