Abstract

Fishing using gill net has been done widely by fishermen in Southeast Maluku Regency, including in Ohoi Tuburngil waters north east Kei Besar District. Fishing activities using this type of fishing gear are still ongoing as a source of income for local community. The objective of this research were to (1) analyze the composition of the catch with a surface gill net based on the catching time and (2) compare yields and determine the best fishing time in the fishing process with surface gill net. The research methods were experimental fishing, observation and interview. The results showed that the total number of fish species caught with surface gill net during the research was 128 fish consisting of 7 fish species. The value of the diversity index (H') obtained for fishing in the morning was 1,60, at daytime was 1,15, afternoon was 1,30, and at evening was 0,92. According to the criteria for the diversity index, the value of H' less than 1 is categorized as low diversity. The results of the analysis of variance showed that te fishing time has a very significant effect on the catch number at the level of ά = 0.05. Based on the results obtained, it showed that the evening catch was significantly different from that in the morning, the daytime and the afternoon, while catch in the afternoon was significantly different from the day time and different from the morning time.

Abstract

Fish resources Utilization in Southeast Maluku waters uses fishing gear, one of them is the bottom gill net. This study aims to determine the composition of fish species caught with different bottom gill net mesh sizes and the effective mesh size. The method used in this study was an experimental method of fishing with different mesh sizes, namely 2.5 inches and 3 inches, as well as data analysis using the paired sample t test. There were five types of catch obtained at a mesh size of 2.5 inches, namely Bubara fish (Carangoides bajad) totaling 54 individuals (22.41%), Cockatoos (Skarus dimidiatus) 46 individuals (18.67%), Samandar (Siganus canaliculatus 35 individuals (14.52%), Sikuda (Lethrinus atkinsoni) 39 individuals (12.45%) and Jackfruit seeds (Parupeneus indikus) totaling 24 individuals (9.96%).The mesh size of 3 inches obtained the type of Cockatoo fish (Skarus dimidiatus) totaled 27 individuals (30.58%), Jackfruit seeds (Parupeneus indikus) 14 individuals (15.91%), Bubara (Carangoides bajad) 13 individuals (14.77%), Samandar (Siganus canaliculatus) 11 individuals (12 .50 %) and sand (Pentapodus nagascokiensis) 6 (6.62 %). The total weight of the catch in basic gill nets with different mesh sizes, namely a 2.5-inch mesh size, obtained a total catch weight of 49,731.44 grams with an average catch per operation of 4,521.04 grams, while for mezh size 3 inches of 21,615.51 grams with an average per operation of 1,965.05 grams. Based on the paired sample t-test, it showed a significant difference in the use of different mesh sizes on the total weight of the catch, where the total weight of the catches obtained in the 2.5-inch treatment was more than in the 3-inch treatment, which means that hypothesis H1 is accepted Hₒ rejected.

Abstract

Hand line is a type of fishing gear that is active and environmentally friendly and is often used by traditional fishermen to catch fish with high economic value. The right bait is one of the factors for maximizing catches. Fishermen around the village of Fiditan, Jellyfish Island, Kota Tual generally use various kinds of bait, such as Momar fish (Decapterus sp), Sikuda fish (Letrinus lenca) and Nipah worms (Namalycastis). This research was held in November – December 2022. The objectives are: to know the composition of hand line catches with different baits and to determine the type of bait that gives the most catches. This research is expected to provide information and knowledge to fishermen about hand line fishing gear units using different baits. Data analysis used a randomized block design, with baits used were Momar fish, Sikuda fish and Nipah worms. During the study, a total of 346 fish were caught consisting of Sikuda fish (Letrinus lenca) with a total of 294 fish (85.5%), followed by Gora fish (Lutjanus carponotatus) 25 individuals (7.33%), Sand-sand fish ( Taeniura ymma) 20 individuals (1.16%) and the smallest catch was Gace fish (Lutjanus malabericus) with a total of 1 fish (0.29%). The results of the analysis of variance showed that the Fcount for the treatment (8.66) was greater than the Ftable (0.05); 14:2) (88.5) so statistically H0. This means that the difference in the use of bait has a very significant effect at the level of ά = 0.05 on the catch. The BNT test results also showed differences in the value of each bait so that it was concluded that the three baits used by fishermen had a significant difference in the catch obtained with Sikuda bait with the highest yield, followed by Nipah worm and Momar fish bait.
