Funcional Interaction of Squid (Loligo chinensis. Gray 1849) Egg Attachment on Atractor Squid Aggregate Device in Tuing Sea Bangka Regency.

Abstract

Numbers of armada and fishing gear modernisation are not accompanied by squid stock enrichment program. Atractor squid aggregate device is one of the efficient technology for squid stock enrichment program development in the future. Atractor squid aggregate device form and material recently are less applicative for fisherman condition in the remote area. Therefore atractor squid aggregate device model modified to become less complicated by using cheaper and easy to find material based on local potency in the area. This research was conducted in Tuing Sea, Bangka Regency, Bangka Belitung Province since October 2012 until June 2013 by using 12 units of atractor squid aggregate device. There are two type of squid aggregates devices in this research which are 6 units square form with wood material and 6 units cylindrical form made from used drum. Each atractor squid aggregate device drowned in 3 meter and 5 meter depth and monitored 5 times. The result of t-test show that time of monitoring factor and atractor squid aggregate device form are two factors which most influenced the squid eggs attachment to aggregate device. The result of research shows that squid eggs attach effectively to cylindrical form Squid aggregatee device, 3 meter depth and in November – Desember 2012. Monitoring in November-December 2012 was predicted as time of squid spawning in the study site because of many egg capsules of squid attached. Atractor squid aggregate device that cylindrical form was more enclosed and protected so squids prefer to attach their eggs than rumpon atractor that box form. During the five times monitoring of the study, from 12 units of atractor squid aggregate device that surveyed were found as many as 3,449 egg capsules attached with the number of capsules as many as 3-6 eggs of squid. Spesies of fish that are always found in the location of the drowned of atractor squid aggregate device is Lutjanus lutjanus.
