Abstract

Fishing technology has always been developed to increase fishing productivity and more eco-friendly the environment. This study of fish schooling characteristics was conducted on a Fixed-Lift Net with LED lights using hydroacoustic method to determine the swimming activity of fish before midnight, at midnight, and after midnight. Experimental fishing method implemented by following fishing operations in the water of Pangkajene Kepulauan Regency in April to August 2019. The study showed that just before midnight, the fish in Fixed-Lift Net area tended to be at a depth 3-6 meters below the surface of the water and is dominated by the emergence of medium group and big group. At midnight the fish tend to be at a depth of 4-16 meters are dominated by the emergence of Small category fish (individually or solitary). Detection of fish in after midnight tends to be at a depth of 3-14 meters and is dominated by the appearance of medium group fish. Medium and large groups indicate large groups of fish. This can be used by fishermen to make the hauling process before and after midnight.

Abstract

This study aims to determine the potential zone of Millenium Gill Net fishing gear which is scattered in the waters of the Sangkarrang Islands. The research was conducted in April-September 2019 in the waters of the Sangkarrang Islands District with a fishing base location of 5 ° 6'13.2664 "LS and 119 ° 25'59.2453" East Longitude. Data were collected by participating in fishing activities, observation and interviews with fishermen respondents. The catch coordinate data and the catch, besides that, the data is also obtained by downloading the ocean color in the form of sea surface temperature data and chlorophyll-a which is processed using the ArcGis map maker software. The research results obtained four points. First 5o2'15 "-5o2'55" LS and 119o24'30 "-119o25'0" East Longitude, Second 5o2'55 "-5o3'40" LS and 119o24'59 "-119o25'10" BT Third 5o5'7 "-5o5'52" LS and 119o23'35 "-119o24'0" East Longitude and the fourth 5o5'7 "-5o5'52" LS and 119o23'35 "-119o24'0" BT. For potential fishing zones I and II are dominated by outboard motor boats <1 gt while in potential zones III and IV 3 gt motor boats use basic gill nets.
