Abstract

This research was conducted from April-Mei 2013 in the Waters around the Estuary Sei Undan, Kabupaten Indragiri Hilir, Riau Province. The aim of this research is to understand the distribution and abundance of epiphytic diatom presenting on the trunk of the Avicennia sp which is related to water quality factor. Survey method was applied on this research where data were obtained by direct observation in the field. The samples of epiphytic diatom were analyzed in the Laboratory of Marine Biology. Water quality parameters were measured in situ.Six species of epiphytic diatom were found on the trunk. The abundance of epiphytic diatom on the trunk ranged from 0 to 9.59 ind/cm2. Beside that, water quality parameters were in the sufficient range for marine epiphytic diatom.Keywords: epiphytic, diatom, avicennia sp, Sei Undan

Purpose of this study is to know efficiency level of longliner fishing catches, which has been landed in fishing port and its factor influenced. The resultshow that the efficiency level of fishing catches landing time was 56.98-72.73%, with uploadingefficiency time was 64,65% in average. There is seven free variable influence on the timeefficiency of fishing landing, with the value r=0,836 and R2=83,6%. So the diversity ofindependent variable gives the contribution to the diversity assess of time efficiency as 83,6%.Keyword : Fishing port, long line, mooring time, time efficiency, tuna (thunnus sp)

Abstract

Purpose of this study is to test effectiveness of PVC and conventional trap to catch C. Batrachus as main fishing target. C. Batrachus behavior on the fishing capture process by PVC and conventional trap were observed in the tank 9 x 1 x 1.5 m in dimension and under video camera (JVC, HDD Evero 35 X optical zoom) recording. The result show that, the PVC trap was most effective to catch, which the total fishing catches were 21 individuals. The average of duration time was spent between 1.53 – 183.15 minutes for each individual to enter in to PVC trap during observation. While, the conventional trap was caught 8 individuals, which was reqiured time between 3.23 – 424.12 minutes. The capture process of C. Batrachus was varied, they were surrounded in front of tunnel of the trap before go toinside it as well as another individual directly go to inside the trap. The effectiveness of capture process was influenced by short time the C. Batrachus enter to the trap, which C. Batrachus was required times 1.53 minutes each individuals in average for PVC trap and 3.23 minutes for conventional trap. The C. Batrachus behavior related to the fishing capture process was discussed in this paper.Key words: Cathfish (C. batrachus), Conventional Trap, PVC Trap, Trap, Tank
