Pengaruh Rumpon Portable dan Jenis Lampu terhadap Hasil Tangkapan Bagan Tancap di Teluk Palabuhanratu
Abstract
Nowadays, usage of lamps on liftnet fisheries in Palabuhanratu has experienced many changes. All liftnets, both mobile and stationary, previously used pressured kerosene lamps but now they use electric lamps. Type of lamps used in this research is light emitting diode (LED) because of its low energy consumption and more durable. Fish aggregating devices (FADs) have long been used in capture fisheries, including liftnets. Liftnets catch fish more efficiently by concentrating fish schools daytime and catch them at night fishermen by means of lights as fish attractor. The objectives of this research are (1) to compare fish catch between two liftnets equipped with 4 FADs but different in types of lamp, i.e. LED (liftnet A) and flourescent (liftnet B), (2) to compare fish catch between two lifnets equipped with flourescent lamps but different in number of FADs, i.e. 4 FADs (liftnet B) and 2 FADs (liftnet C). This research is conducted in experimental fishing approach and each lifftnet was operated 20 times. Statistical analysis using t test concluded a signifikant difference in catcah of small shrimp, hairtail fish and anchovies (α = 0,05) between liftnet A and B, and a signifikant difference in catches of anchovy, sardines, hairtail fish and small shrimp between liftnet B and C (α = 0,05).
