Abstract. This research was conducted onJuly 2018 in Lake Laut Tawar, Aceh Tengah District.This study aims to determine the abundance of fingerling fish and the availability of natural feed found in Lake Laut Tawar. The gillnet was used to sample the fingerling fish at three stations, including station 1 (One-one), station 2 (Toweren) and station 3 (Rawe) forweek. The parameters of measured water quality are at temperature, pH, DO (dissovlet oxygen), depth, and brightness. Sampling of natural feed (plankton extraction) was carried out at the place of fish collection, then prepared a standard plankton, and identified using microscopy. The results showed the highest abundance of fingerling fish obtained was thekeperas fish (Cyclocheilichthys apogon), with an abundance of 75%. While the lowest abundance value is kawan fish species (Poropontius bargensis), with 4% abundance value, and the highest plankton abundance in Lake Laut Tawar waters is at station 2 with an abundance value of 69.2485 ind / mL and the lowest abundance value is at 1 with an abundance value of 38.0637 ind / mL. Based on the results of the research conducted, it can be concluded that the abundance of fingerling fish is related to the availability of natural food in the waters of Lake Laut Tawar.Keywords: Abundance;Fingerling fish;Natural food;Lake laut tawar.

Barramundi Lates calcarifer is a high economic value fish in Indonesia and Southeast Asia countries. However, the aquaculture system still experiences problems, including the high cost of production, specifically from feed, which is due to its relatively slow growth and low digestibility. Therefore, this study aims to determine alternative ingredients that can be used in the fish diet to improve feed utilization and growth performance using pumpkin flour Cucurbita moschata. A completely randomized design (CRD) with 6 treatments and 3 replications was adopted in this study. The tested diet was (A) diet without pumpkin flour (control), (B) with 5% (C) 10% (D) 15% (E) 20%, and (F) 25%. The size of the Barramundi samples was 3-4 cm on average and the body weight was 1-3 g at the stocking density of 15 fish/container. The fish fed as much as 10% body weight daily, which is divided into 2 times, namely 08.00 AM and 4.00 PM for 60 days. The results showed that the addition of pumpkin flour had a significant effect on weight gain, daily and specific growth rate, survival, feed efficiency, conversion ratio, and carcass protein (P0.05). The diet with 5% pumpkin flour gave the best results over other treatments, with an average weight gain of 0.761 g, feed conversion of 1.578, feed efficiency of 63.455%, and a daily and specific growth rate of 0.012 g and 0.738%, respectively, The highest carcass protein content was found in the control treatment with a value of 18.210%, which was not significantly different from the 5% pumpkin flour treatment. Therefore, it is concluded that pumpkin flour can be added to the Barramundi diet as much as 5%. Keywords: Barramundi, Snapper, pumpkin, feed utilization

The scad (Decapterus sp.) is one species commonly caught using purse seine and landed at the Pusong Fish Landing Base, Lhokseumawe, Aceh. The fishermen at this site do not have accurate knowledge about the fishing season of the scad, which leads them to miss out on peak fish catching season and increases the ambiguity about the fish landing data. The goal of this research is to compute the trend of Catch Per Unit Effort (CPUE) for scad fisheries over the last five years (2013-2017) and to examine the fishing season trends of scad landed at Pusong fish landing base. This study took place at the Pusong Fish Landing Base in August 2020. The moving average approach was used to process catch data from 2013 to 2017. Primary and secondary data about scad production and number of fishing trips were used to compile the research findings. The results showed that the CPUE for purse seine catch landed at Pusong Fish Landing Base varies from year to year. The highest CPUE value was recorded in 2015 with 442,534 kg/trip, and the lowest was in 2013 with a value of 27,674 kg/trip. The fishing season index for Scad (Decapterus sp.) has a high rating, indicating that this fish species can be caught all year. Based on the fishing season identification criteria, the fishing season index value greater than 100% indicates the peak season. Results from this research indicate that the peak season for scad landed at Pusong Fish Landing Base occurs in July, August, September, October, and November, with their index values of 151%, 146%, 119%, 122%, and 126% respectively. A fishing season index score of less than 100% indicates low season, this was recorded for January, February, March, April, May, June, and December (48%, 97%, 57%, 90%, 62%, 86% and 97%).Keywords:ScadFishing Season IndexCPUE

The existence of fish aggregating devices (FADs) in a waters is able to establish a new fishing ground that potential waters. FADsareable 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 atPusongWaters, 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 andno 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 usedFADs is more effective compared to thea 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. Penelitian ini bertujuan untuk menganalisis komposisi hasil tangkapan purse seine yang menggunakan rumpon dan purse seine yang tidak menggunakan rumpon, dan menilai efektivitas rumpon dalam mengumpulkan ikan. Penelitian ini dilaksanakan pada 01 - 28 Februari 2018 bertempat di Perairan Pusong, Kota Lhokseumawe. Metode penelitian yang digunakan adalah metode survei, yaitu dengan mengikuti nelayan dalam kegiatan penangkapan ikan, baik nelayan purse seine yang menggunakan rumpon dan nelayan purse seine yang tidak menggunakan rumpon. Data ikan hasil tangkapan yang diperoleh dihitung jumlah ikan hasil tangkapan dan diidentifikasi spesies ikan dan selanjutnya dibandingkan dengan hasil tangkapan nelayan yang menggunakan rumpon dan ikan hasil tangkapan nelayan yang tidak menggunakan rumpon. Total hasil tangkapan purse seine selama penelitian sebanyak 4.320 kg terdiri dari kembung (Rastrelliger sp.) 1.280 kg (29,63%), layang (Decapterus sp.) 350 kg (8,107%), cakalang (Katsuwonus pelamis) 845 kg (19,56%), tongkol (Euthynnus affinis) 720 kg (16,67 %), tegang ekor/tetengkek (Megalaspis cordyla) 300 kg (6,94 %), talang/daun bamboo (Scomberoides lysan) 140 kg (3,24%), dan ayam-ayam (Abalistes stellaris) 685 kg (15,86 %). Dari kedua jenis kegiatan penangkapan ikan tersebut, maka purse seine menggunakan rumpon lebih efektif dibandingkan purse seine yang tidak menggunakan rumpon sebagai daerah penangkapan ikan.Rasakan keseruan bermain di om88 dengan peluang menang yang lebih besar.
