“…D. macrosoma is recorded as one of the most abundant fishes in Bali Strait [7]. This fish was also reported as the main catch from purse seine in some waters in Indonesia, such as Sibolga waters [13], South China Sea [27], Kendari waters [28], Java Sea [29,30], Prigi waters [31], and Watampone waters [32]. In the South China Sea, D. macrosoma was already classified as highly exploited [33], while it was overexploited in the Java Sea [34].…”

Shortfin scad (Decapterus macrosoma) is one of the most abundant catches of purse seiners in Bali strait. This study aimed to reveal the length-length relationship, the length-weight relationship, and to estimate the length at first maturity (Lm50) and the length at first capture (Lc50) for D. macrosoma in the waters of Bali Strait. The samples were collected from Pengambengan Fishing Port from June to December 2018. A total of 3,341 shortfin scads were fork length measured and weighed during the research. There were 420 fish from the total sample fish measured more for the total and standard length and dissected. The sex and maturation stage determination were identified by gonad visual characteristics. The relationship between lengths was determined using linear regression, whereas the length-weight relationship was determined using power regression. The length at first maturity and capture were determined using the logistic curve. The lengths (total, fork, and standard) were highly related to each other. The lengths were also highly related to the weight. The growth pattern of the shortfin scad was hyperallometric. The Lm50 for D. macrosoma was 164 mmTL for males and 162 mmTL for females. They were shorter than the Lc50, which was 184 mmTL.

“…All specimens of Indian Scad were mature or adult fish. According to Pralampita and Chodriyah [12], D. russelli achieve adults for males in a total length of 21.2 cm and females at 18.97 cm. Meanwhile, it different for Torpedo Scad, which had a total length lower than the size at maturity, which indicates that all species were immature or maturing fish.…”

Total Mercury (THg) Concentration in Indian Scad (<i>Decapterus russelli</i>) and Torpedo Scad (<i>Megalaspis cordyla</i>) from Southern Waters of Binuangeun, Banten

The high level of fish consumption was the main factor in the vulnerability of Hg exposure to the human body. The preliminary information of the total mercury (THg) concentration of Indian scad (Decapterus russelli) and Torpedo scad (Megalaspis cordyla) from Binuangeun fish auction in Lebak, Banten, Indonesia, was presented in this research. The objective of this research was to understand the distribution of THg in each organ of D. russelli (muscle, gut tissues, gonad, and eggs) and M. cordyla (muscle, liver, and gut contents). The results showed that THg in all samples were below the National Regulation limit from the National Agency of Drug and Food in mg/kg ww. THg gonad from D. russelli was showed highly significant (P < 0.01) lower compare THg in muscle, gut tissues, and eggs. Pearson’s correlation from THg in each organ of D. russelli compare to total weight and total length showed that concentration of THg in gonad highly significantly (p < 0.01) correlated with total body weight (r2 = 0.97) and total length (r2 = 0.96). M. cordyla was showed no correlation of THg in muscle compare to total length and total weight. The present study showed that D. russelli could accumulate higher mercury compare to M. cordyla and need caution while consuming this fish.

“…The catches were fish that were about 20 cm in size. Scad Fish measuring around 20 cm is a fish that deserves to be caught because it has passed the age of first gonad maturity (Liestiana et al 2015;Najamuddin et al 2004;Pralampita and Umi 2010). Small fish that are not caught are expected to have the opportunity to grow and reproduce to maintain a balance of stocks in the waters.…”

Purse Seine fishing gear is a fishing gear operated by several fishermen in the WPP NRI 571. Purse seine is a type of fishing gear that classified as surrounding nets, which is an active fishing gear to catch pelagic fish which who generally live in groups in large flocks. The main catch is Mackerel scad (Decapterus spp). The purpose of this study was to determine the level of environmental friendliness of the Purse seine fishing gear in PPS Belawan. The method used in this study is by using a score based on the Code of Conduct for Responsible Fisheries (CCRF) criteria, fish physiology analysis, and also analyze the suitability of fishing gear with the regulation of Permen KP.71 of 2016. Based on the results of the study, it can be concluded that physiologically fish include into fish fit for catching with a total length ranging from 19-24 cm, the average size of the first caught (Lc) at a length of 15 cmFL, the size of the first sentence gonads (Lm) 19.6 cmFL, Km. Sumber Baru does not meet the Regulations of the size of the vessel, and the Purse Seine fishing gear is very environmentally friendly with a score of 32 points.This Lc value is smaller than the Lm value. From this result, it is known that most of the scads caught have not passed the first gonadal maturity size (Lc<Lm), but in terms of the specifications of the fishing gear, they have adjusted to the applicable regulations
