Efektivitas Bubu Lipat Modifikasi dengan Jenis Umpan Berbeda pada Penangkapan Lobster di Perairan Pelabuhanratu.

Abstract

The purpose of this research is to find out the effectiveness the modified of collapsible pot and the use of bait on catching lobsters. This research is conducted by the experimental fishing method. Design research using the Completely Randomize Design with two factors. The factors is collapsible pot type and type of bait with the number of catching repeats as much as 20 trip. Factors of collapsible pot consists of the swimming crab pots as the standar of collapsible pot (S) and two modified of collapsible pots. The modification is the pot that have one funnel on aside (PS) and the pot that have one funnel on top (PA). The bait factors consists of bait fish Fringescale sardinella (Sardinella fimbriata) as standard bait and worm (Lumbricus rubellus) as an alternative bait. The catch is consist of the main target catches is that the spiny lobster (Panulirus spp.) and sideline catches (by-catch) or total catch. The totally composition of catches dominated by sideline catches (by-catch) about 67,35 %, and target catches about 32,65 %. The by-catch is dominated by species of swimming crabs about 37 (37,75 %), cuttlefish (Sepia sp.) about 23 (23,47 %), fish about 5 (5.10 %) and mantis shrimp (1.02 %). The main target catches consist of scalloped spiny lobsters (Panulirus homarus) about 30 (30.61 %), one painted rock lobster (Panulirus versicolor) (1.02%), and one ornate rock lobster (Panulirus ornatus) (1.02 %). Comparison of two types of catches bait has a value that is not significantly different (α = 5 %). Between three kinds of pots, catches standar collapsible pot better than one funnel aside collapsible pot, and one funnel aside collapsible pot better than one funnel on top collapsible pot (S > PS > PA).
