Tujuan dari penelitian ini adalah untuk mengetahui lama penyinaran berpengaruh terhadap kecerahan warna, pertumbuhan panjang dan berat serta kelangsungan hidup ikan komet (Carassius auratus). Penelitian dilaksanakan di kampus C Fakultas Perikanan Universitas PGRI Palembang. Kegiatan penelitian dilakukan selama 30 hari. Ikan uji yang digunakan adalah Ikan komet ukuran 5 cm dengan menggunakan akuarium sebanyak 12 buah yang berukuran 40 x 30 x 20 cm. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri 4 taraf perlakuan dengan 3 kali ulangan yaitu perlakuan P0 dipelihara tanpa adanya perlakuan penyinaran, P1 lama penyinaran (LP) 6 jam/hari, P2 lama penyinaran (LP) 12 jam/hari, dan P3 lama penyinaran (LP) 18 jam/hari. Hasil penelitian menunjukkan bahwa perlakuan dengan lama penyinaran selama 18 jam setiap harinya (P3) memberikan hasil terbaik terhadap parameter kecerahan warna badan ikan komet (Carassius auratus) sebesar 20,96 serta pertumbuhan berat rata-rata dan panjang ikan komet (Carassius auratus) yang terbaik terdapat pada perlakuan P3 dengan berat 0,66 gram dan panjang 0,4 cm. Untuk kelangsungan hidup ikan komet (Carassius auratus) nilai tertinggi tertinggi terdapat pada perlakuan P2 yaitu sebesar 93.33%.

. Pengembangan perikanan tangkap berbasis CCRF dapat dilakukan untuk memanfaatkan potensi perikanan tangkap secara optimal. Penelitian ini dilakukan untuk menganalisis alat tangkap jaring insang berdasarkan dokumen CCRF sebagai kelanjutan dalam memberikan kebijakan dalam penggunaan alat tangkap. Metode pengambilan data yaitu menggunakan kuesioner selanjutnya dianalisis menggunakan statistika deskriptif. Hasil penelitian menunjukkan kekurangan dari penggunaan jaring insang yaitu terdapat pada mutu ikan yang tertangkap cenderung sedikit mengalami cacat fisik (bagian operkulum), serta masih tertangkapnya hasil tangkapan sampingan. Kesimpulan dari penelitian yaitu bahwa alat tangkap jaring insang direkomendasikan untuk digunakan oleh nelayan karena sesuai dengan kriteria alat tangkap ramah lingkungan yang memenuhi ketentuan dokumen CCRF.

Haris et al, 2019. The Analysis of Water Suitability for Floating Net Sprouts in Sirah Pulau Padang, Ogan Komering Ilir District, South Sumatra Province. JLSO 8(1):20-30.The purpose of this study is to analyze the level of water suitability of the floating net sprouts in sirah pulau padang, ogan komering river, Serdang Menang Village, OKI South Sumatra Regency based on water physical and chemical parameters. This study was conducted on July - August 2018 at the Komering River, Ulak Jermun village, Terusan Menang Village, and Mangun Jaya Village, OKI District, South Sumatra. The data of sampling was divided into 3 stations, they were; station 1 was Ulak Jermun Village (3 ° 18'45.48 "LS and 104 ° 53'5.32" BT), station 2 was Terusan Menang Village (3 ° 17'14.13 "LS and 104 ° 52'46.78 "BT), and station 3 was Mangun Jaya village (3 ° 18'14.92" LS and 104 ° 52'59.48 "BT). The data of Samples were tested at the chemical laboratory in Palembang Public Water Fisheries and Extension Research Institute directly. The results of the study was for Station 1, Station 2, and Station 3 with a value was  48% with a good feasibility information. The results of measurements of water quality parameters, the pH was about 6.6 - 6.7, temperature was about from 24., 53 - 26.93oC, DO 3.93 - 4.36 mg / l, ammonia was about 0.78 - 0.16 mg / l, water brightness was about from 34.67 - 43.33 cm, CO2 4.53 - 5.03 mg / l, depth 2.36 - 2.47 m, current velocity was about 0.38 - 0.44 m / s, nitrate was about 0.37 - 0.439 mg / l, phosphate was about 0.009 - 0.225 mg / l and the bottom substrate of water was mud.

Small-scale fishery activities that often occur in coastal areas Dumai City are part of the socio-ecological system, where the waters around the coastal areas provide services to several fishermen who live around and are interrelated with each other. This study aimed to identify the dynamic of social and ecological systems to the sustainability of small-scale fisheries in the waters of Dumai City. The are 3 research location in village, namely Pelintung, Tanjung Palas, and Bangsal Aceh. The research method is a survey using interview techniques with a questionnaire. The data analysis in this research is descriptive qualitative, fishing gear productivity, fishermen’s income, and the relationship dynamics of the catch. The social characteristics of fishermen can be shown from their education, where most of the fishermen in Dumai City have elementary school education. The wives of fishers in Dumai City are mostly still taking care of the household, and only a few are processing fish. Fishers in Dumai City also carry out the duration of fishing operations based on the type of fishing gear (gillnet, scoop net, and portable trap). For the last seven years, the productivity of fishing with gillnet fishing gear has increased, while for scoop net and portable trap fishing gear, it has tended to decrease. The RPUE value of gillnet fishers shows the highest profit, where the average income in one trip is IDR 1,086,050.00 compared to other fishers. The fishermen’s perception also shows that the catch of gillnet fishers during the last five years has increased.
