“…The data showed that the length of the fish ranges from 95 mm to 222 mm. The total length of S. leptolepis caught in Tomini Bay during this study was slightly different from the same species found in Wondama Bay with a range from 100 to 240 mm (Sala et al, 2018) and also the S. leptolepis size at the Bintan waters fishing areas ranging of 102-215 mm (Septiyawati et al, 2020). The size of the males and females caught were not much different (p-value > 0.05).…”

Highlight ResearchThe fishing area of S. leptolepis in this study was confirmed to be located in Tomini BayThe fish samples were gathered randomly from fishers’ catch using purse seinesThe growth curve for the male and female fish data were both plotted following the trend of the Von Bertalanffy equationThis study estimates the growth parameters, mortality, and exploitation rates of the male and female fish separately.AbstractComprehensive data is required for implementing sustainable fisheries management. Population dynamic and stock assessment aspects of Selaroides leptolepis species in Tomini Bay have not been entirely reported. This study aimed to determine the fishing mortality rate and exploitation status of S. leptolepis in Tomini Bay by calculating Von Bertalanffy growth model parameters (L∞, K, t0) then plotting them into Pauly's empirical equation. The sampling was conducted monthly from April to September 2020 at Gorontalo City Fishing Port. Samples were collected randomly from five commercial fishing vessels shortly after the fishermen landed their catch at the fishing port. All fish samples were confirmed to be obtained by the fishermen from Tomini waters. The growth parameters of the samples were analyzed using FiSAT II based on Von Bertalanffy mathematical model. While the mortality and exploitation values were calculated manually using Pauly's equation. The study showed that the growth parameter values of S. leptolepis in Tomini Bay were 245.47 mm, 0.49/year, and -3.04/year for males, while 227.80 mm, 0.63/year, and -2.72/year for females separately for L∞, K, and t0. The total, natural, and fishing mortality rates were 3.06/year, 0.61/year, and 2.45/year for males and 0.99/year, 0.74/year, and 0.25/year for females. The analysis results showed that the female's natural mortality (M) was higher than the male. In contrast, the fishing mortality (F) and total mortality (Z) of male fish exceed the female. The exploitation value of males (E=0.80) was greater than that of females (E=0.26).

“…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.

Indian mackerel (Rastrelliger kanagurta) in the waters of Kupang Bay is part of the wealth of biological resources that the population needs to be maintained in order to be sustainable. High exploitation rate of Indian mackerel fish is due to the large market demand and high levels of consumption, causing many fishermen to carry out continuous fishing. This research aims to determine the growth patterns and dynamics of fish populations which can be used to determine the utilization conditions of R. kanagurta through estimating growth parameters. in the waters of Kupang Bay. The research was conducted in September 2022. Total sample of fish was 150. The data collected includes length and total weight. Data analysis used Microsoft Excel software which was used to analyze the relationship between length and weight and FISAT II was used to analyze fish growth parameters. The results of the analysis of the long-weight relationship between male and female mackerel showed that the growth pattern was negatif allometric with estimated of growth parameters L∞ = 28.40 cm, K = 0.51 years, and t0 = -0.32 years. The total mortality rate (Z) was 4,68, the natural mortality rate (M) was 1,17, the mortality rate from fishing (F) was 3,5, and the exploitation rate (E) was 0,75 per year.
