“…Although the sample size is large enough it covers 80% of the total known maximum length, but for this species is generally smaller than the total size of a reported total of 120 cm. The difference in total length size may be due to the dominance of small size fish in this geographic area or environmental constraints, Rochmady & Susiana [24], Susiana et al [25]. The values of 'b' for this fish species have not been reported.…”

Length-weight relationship (LWR) species Epinephelus fuscoguttatus Forsskål, 1775 by gender (male and female) were collected from September 2016 to June 2017 in Bobong Taliabu waters, North Maluku, Indonesia. Fish captured using bottom trap, size 80 x 60 x 35 cm with mesh size 5 cm. LWRs of significant male and female E. fuscoguttatus (P<0.05) were calculated as W = 0.0098 L 3.1475 (r 2 = 0.9252), W = 0.0752 L 2.5030 (r 2 = 0.9029), and W = 0.9987 L 1.6789 (r 2 = 0.9093) for both. This study recorded the new maximum length by sex of E. fuscoguttatus.

“…Rumus untuk menentukan potensi lestari maksimum (MSY) hanya berlaku bila parameter b bernilai negatif, artinya untuk penambahan akan menyebabkan penurunan CPUE (Rochmady et al, 2011;Rochmady & Susiana, 2014;Tangke et al, 2018). Apabila dalam perhitungan diperoleh nilai b positif, maka perhitungan potensi dan upaya penangkapan optimum tidak dilanjutkan, tetapi dapat disimpulkan bahwa penambahan upaya masih memungkinkan untuk meningkatkan hasil tangkapan.…”

Mapur waters is one of the potential areas for demersal fish distribution in Bintan waters. The purpose of this study was to investigate the effort of catching painted sweetlips fish (Diagramma pictum), Maximum Sustainable Yield of Painted Sweetlips Fish and investigated the amount of Painted Sweetlips Fish catches allowed (JTB). The research method used is the survey method, which is direct observation at the research location by recording fishing operations such as fishing gear and catches through direct interviews with fishermen working in fish storage warehouses. Data taken in the form of primary data and secondary data. The results showed that the effort of catching Painted Sweetlips Fish on Mapur waters was 314.00 units, with the MSY value was 713,016 kg/unit. So that the amount of catch allowed (JTB) is 80% from MSY which is equal to 570.41 kg/unit, with the utilization rate of Painted Sweetlips Fish on which is equal to 89%.

“…Namun demikian, penurunan tingkat pemanfaatan dapat juga bermakna bahwa potensi ikan di perairan bisa saja tidak mengalami perubahan signifikan karena adanya tekanan eksploitasi yang konstan. Namun demikian, laporan beberapa peneliti menunjukkan bahwa dugaan terakhir tidak dapat diabaikan oleh karena penurunan tingkat pemanfaatan dapat saja telah terjadi overeksploitasi, seperti yang dikemukakan Tangke (2014), atau pada kasus cumi-cumi di perairan Pangkep, Sulawesi Selatan (Rochmady & Susiana, 2014). Walaupun demikian, kemungkinan perlu mendapat perhatian dan kajian lebih lanjut.…”

The study was conducted in December 2016 to February 2017 in East Halmahera waters with the aim to examine the relationship between the length of weight and potential and the level of utilization of tuna. The results showed that the long frequency distribution of tuna was ranging from 10.0-28.2 cm, with a maximum length value of 29.93 cm, a growth coefficient of 0.74 per month and a measure of fish worth catching for spawning. The relationship between the weight of tuna in East Halmahera waters is W=0.0078L3.2982, where the length of tuna is greater than this weight increase due to environmental conditions and oceanographic parameters that affect the growth of tuna. The results of the MSY analysis or the sustainable resource potential of tuna in East Halmahera waters using the Fox method, found that the MSY value or sustainable potential of tuna was 4,176.54, with a maximum effort level of 8,047 Trips. This utilization rate is still low from the value of MSY and continues to decline this is due to the low value of fishing efforts.
