Knowledge on seasonal fishing pattern is essential in fisheries research in order to increase the effectiveness of fishing and at the same time protecting the fishing ground from excessive fishing practices. Determining the seasonal fishing pattern of large pelagic fishes, namely large tuna (yellowfin and bigeye), small tuna (mackerel) and skipjack tuna were the objective of this study. Data from the 2013-2015 fishing operation time series were used to analyze the fishing season using the percentage average per unit effort (CPUE) method. The main focus of this study was purse seine fishery. The research showed that high fishing season of large pelagic fishes allegedly occurred during May to July, which reached its peak on May. On the other hand, low fishing season occurred during January to April, with the lowest on March. There were similarities between large tuna, small tuna and skipjack in term of their seasonal fishing pattern, although they did not show any good correlation (r<0.5). This might due to fact that even tough large tuna, small tuna and skipjack tuna shared the same ecological niche but apparently, they did not show any interaction (symbiosis) but competition.

Fish Aggregating Devices

The existence of fish aggregating devices (FADs) in a waters is able to establish a new fishing ground that potential waters. FADs are able to attract the attention of the gathering of fishes and other aquayic organisms around it, increasing the density of fish around FADs can increase the chances of successful catching operation, and therefore the FADs has benefited significantly to increase the capture fishery production significantly. The purposes of the research were to evaluate the catching composition of purse seine production  using FADs and non FADs, and to examine the fectiveness of FADs. This research was conducted on February 1 - 28, 2018 located at Pusong Waters, Lhokseumawe City. The survey  method was used in this study. The direct sampling by following the fisherman in fishing activities was performed both the purse seine with FADs and no FADs. Total purse seine catches during the research were 4,320 kg consisting of Long Jawed Mackerel (Rastrelliger sp.) 1,280 kg (29.63%), Decapterus Fish ( Decapterus sp.) 350 kg (8,107%), skipjack tuna (Katsuwonus pelamis) 845 kg (19.56 %), tuna fish (Euthynnus affinis) 720 kg (16.67%), Torpedo scad (Megalaspis cordyla) 300 kg (6.94%), Queenfish 140 kg (3.24%), and starry triggerfish (Abalistes stellaris) 685 kg (15.86%). It was concluded that the purse seine used FADs is more effective  compared to the a purse seine that does not use FADs.Keberadaan rumpon di suatu perairan mampu menarik perhatian berkumpulnya ikan dan organisme lain disekitarnya, sehingga dapat meningkatkan hasil tangkapan ikan.

Large pelagic fish live on the water surface in groups. Skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), mackerel tuna (Euthynnus affinis), mackerel (Scomberomous guttatus) are species of fishes that mainly catches by fishermen using purse seines. This study aims to determine the length and weight of large pelagic fish in the water of Idi Rayeuk and best the fishing season. This research was conducted in one month. Fish samples were collected from fishermen that used purse seine and landed their catches at the Idi Rayeuk Fishing Port, East Aceh. Additionally, the data was derived from the fishing port time-series during 2015 to 2019. The result showed that the yellowfin tuna (Thunnus albacares) has a length between 37 - 58 cm with a weight of 1.0 - 3.2 kg, skipjack tuna (Katsuwonus pelamis) 32 - 58 cm in length and weight 0.5 - 3.0 kg, mackerel tuna has 33 - 54 cm of length with a weight of 0.6 - 2.5 kg, and mackerel has 44 - 66 cm of length and weighing 0.7 - 1.7 kg. Its also found that the peak season for catching yellowfin tuna (Thunnus albacares) and mackerel tuna is May and June, and the lowest season in December for the yellowfin tuna, and December and January for the mackerel tuna. The peak season for skipjack fishing occurs in May, August, and October, and the low season occurs in November and December. Meanwhile, the peak season for fishing mackerel occurs in May, September, and October, while the low season occurs in January, February, and March.Keywords:Fishing seasonLarge pelagicPurse seineIdi RayeukAceh
