Variasi Periode Penyinaran (Fotoperiod) terhadap Pertumbuhan dan Kelangsungan Hidup Larva Ikan Peres (Osteochilus Kappeni)

This research aimed to determine the effect of photoperiod on the growth and survival rate of peresfish larvae (Osteochilus kappeni). The research was conducted at technical implementation unit of fish breeding center Lukup Badak, Pegasing district, Aceh Tengah on August until September 2016. The method used was Completely Randomized Design (CRD) consisted of five treatments and three replications. The treatments were A (control), B (15 L : 9 D), C (18 L : 6 D), D (21 L : 3 D), and E (24 L : 0 D) using Light Emitting Diode (LED) lamp. The result of ANOVA test showed that the variation of photoperiod gave significant effect on the length growth,weight growth, specific growth rate, long diversity coefficient, and survival rate of peres fish larvae. The Duncan test showed that the best treatment was found at treatment D (21 L : 3 D) with a mean value of length growth was 1,4 cm, weight growth was 0,07 g, specific growth rate was 0,30%/hari, long diversity coefficient was 1,83%, and survival rate was 89,33%.Penelitian ini bertujuan untuk mengetahui pengaruh fotoperiod terhadap pertumbuhan dan kelangsungan hidup larva ikan peres (Osteochilus kappeni).Penelitian bertempat di Unit Pelaksanaan Teknis Balai Benih Ikan Lukup Badak Kecamatan Pegasing Kabupaten Aceh Tengah pada bulan Agustus sampai September 2016.Metode penelitian yang digunakan adalah metode eksperimental dengan Rancangan Acak Lengkap (RAL), terdiri dari lima perlakuan dan tiga kali ulangan.

Determine the fishing season of scad (Decapterus sp.) landed at Pusong Fish Landing Base, Lhokseumawe, Indonesia

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 IndexCPU
