“…Allometric negative growth patterns have also been reported for brown-marbled grouper populations around Pulo Aceh in Aceh Province and for female brown-marbled grouper from Bobong, Taliabu in Maluku Utara Province (Ramadhani et al 2017). Isometric growth patterns have also been reported for male brownmarbled grouper from Bobong Taliabu, Maluku Utara (Tangke et al 2020) and hatchery-raised brown-marbled Grouper in Borneo, Malaysia (Mustafa et al 2015). Similar to the data on brown-marbled grouper populations, the data for other grouper species in Table 3 showed wide variation in growth patterns.…”

Abstract. Fatma, Mallawa A, Najamuddin, Zainuddin M, Ayyub FR. 2022. Biological aspects of brown-marbled grouper (Epinephelus fuscoguttatus) from Taka Bonerate National Park, District of Selayar Islands, South Sulawesi, Indonesia. Biodiversitas 23: 1140-1153. Knowledge regarding biological aspects of fishes such as the brown-marbled grouper can provide important information for fisheries management. This research was conducted from February 2020 to February 2021 to determine the length-weight relationship, condition factor, gonad maturity stage and spawning pattern, size at first maturity and feeding habits of brown-marbled groupers in Taka Bonerate National Park. The sample caught comprised 1042 brown-marbled groupers with a total length (TL) range of 23-97 cm and a weight range of 0.5-17.6 kg. The length-weight equation was W: 0.0001?L2.5955 (R²: 0.8935). For male brown-marbled grouper (n: 569), TL range was 47-97 cm, weight range 1.65-17.60 kg, regression equation W: 0.0002?L2.4731 (R²: 0.7716), condition factor range 0.56-2.36 (mean 1.236±1.019), and length at first maturity 66.34 cm. For female brown-marbled grouper (n: 473) TL range was 23-73 cm (mean 46.84 cm), weight range 0.50-6.6 kg (mean 2.23 kg), regression equation W: 0.0007?L2.1057 (R²: 0.7416), condition factor range 0.55-2.17 (mean 1.225±1.018), and length at first maturity 45.43 cm. The growth pattern was negative allometric with regression coefficient b < 3 for both sexes separately and combined. The majority of both male and female fish caught had mature gonads with indications of a partial spawning pattern. The fish diet was carnivorous, predominantly piscivorous (74%), with gut contents comprising 64% unidentified fish and 26% unidentified decapod crustaceans. Over-exploitation of fish can cause negative impacts on populations, so the relationship between length and weight, condition factors and maturity level gonad of fish can be used in fisheries management.

“…The size structure of Selaroides leptolepis that has been caught was between 4.5-18.5 cm FL with the dominant mode at 11.5 cm FL (Figure 4). This size is still smaller than those caught in the waters of Tomini Bay between 9.5-22.2 cm TL, Wondaman Bay 10-24 cm TL, Ternate 8.2-21.7 cm TL and 5.65-31.82 cm TL and larger than in the Sunda Strait waters 9-18 cm TL and Matang Malaysia 9-17.5 cm TL [21,[29][30][31][32][33]. The difference in the size structure of the caught fish can be caused by differences in fishing gear and mesh sizes used in various waters [13].…”

Small pelagic fish caught with mini purse seines (MPS) in the Java Sea has been exploited for a long time and causes resource sustainability. Policies in preserving natural resources require scientific studies that can provide management options. This research was conducted from March to July 2017 at PPN Pekalongan by recording catches and measuring fork length (FL). The composition of the MPS catch showed that 64% were small pelagic and dominated by Goldstripe sardinella (Sardinella gibbosa) 56.3%, Bigeye scad (Selar crumenophthalmus) 19.3%, and the scads (Decapterus spp) 12.3%, other species with small numbers including Yellowstripe scad (Selaroides leptolepis) by 2.5%. This Yellowstripe scad has a length of between 4.5-18.5 cm FL (average of 10.86 cm FL). The estimated natural mortality (M) is less than the fishing mortality (F). The level of exploitation (E=0.70) indicates that it is overfishing. The management operations that need to be taken to preserve the yellowstripe scad are by regulating the fishing area, determining the size of the allowed MPS nets, and limiting MPS attempts in the Java Sea.

“…Peningkatan suhu dari kisaran optimum akan mempengaruhi biologi reproduksi (Rochmady et al, 2011b;Rakhfid et al, 2019) dan kecepatan makan dari teripang itu sendiri bahkan teripang akan kehilangan selera makan sama sekali (Lewerissa, 2009). Salinitas merupakan salah satu faktor yang mempengaruhi keberadaan dan kehidupan biota di perairan (Purwati, 2003;Susiana, 2011;Susiana et al, 2013;Susiana et al, 2014, Rochmady et al, 2016Susiana et al, 2017;Susiana et al, 2019;Tangke et al, 2020), termasuk teripang. Hasil pengukuran salinitas di perairan Pulau Karas berkisar antara 29-30%0 dihubungkan dengan baku mutu Keputusan Menteri Lingkungan Hidup No.51 Tahun 2004 tentang baku mutu untuk biota laut salinitas yang ada di perairan berkisar antara 33-34%0.…”

The aim of this study was to find out the types of food eaten by sea cucumber sand (H. scabra) and sea cucumber (H. vagabunda), to know the habits of eating sea cucumber (H. scabra) and sea cucumber (H. vagabunda) in Karas waters, Galang District, Batam City. Determination of sampling points using results of the study found 3 types of sea cucumber food namely percentage, Bacillariophyceae 49,82%, Sarcodina 2,23%, Crustacea 24,33%, and 5 types of food Sea Cucumber Seafish with percentage, Bacillariophyceae 50,75%, Sarcodina 3,91%, Crustacea 4,83%, Copepoda 0,52%, and Seagrass Fiber 0,30%.
