“…One of the fish that has become a commodity is the Coral Trout, with a high selling value and market demand, so this fish has become one of the targets for fishermen's catches. Some areas refer to Coral Trout as Janang grouper and red grouper [5]. Economic analysis of the Coral Trout commodity includes factors such as selling price, market demand, production, distribution and government regulations [6].…”

Coral Trout (Plectropomus leopardus) is a species of grouper that is highly valued and the main commodity in Simeulue Regency. This research aims to identify the supply chain, calculate the value of fisheries production and the percentage of production of Coral Trout (Plectropomus leopardus) in the PiSiSi Simeulue MPA. It is hoped that the benefit of this research will be market literacy so that it can be used as consideration for management policies and optimization of fisheries marketing in Simeulue Regency. The research was carried out in March-April 2023 through interviews, field surveys and collecting data on purchases/sales of Coral Trout from collectors. The results of the research show that there is a production value of Coral Trout that is different for each buyer in Simeulue Regency. The production value generated by buyers (collectors) was IDR 1,293,195,632 with a total weight of 10.23 tons. The fisheries sector in the PiSiSi MPA contributes to Coral Trout fish production of 41.47% or IDR. 536.3 million in 2022. Based on this research, Coral Trout fish is sold to local communities, processing coMPAnies and exporters in Belawan, North Sumatra and Jakarta.

“…Cantang grouper is a hybrid between female tiger grouper (E. fuscoguttatus) and male giant grouper (E. lanceolatus). It has a similar morphology to tiger grouper [25], fast growth rate such as kertang grouper, easy to breed such as tiger grouper, and low cannibalism compared to tiger grouper [26]. The hybridization technique is a technique that can increase species diversification, also, it has cultivation prospects that have the opportunity to increase fisheries production in the future.…”

Microplastics are plastic particles in the size of <5 mm. Bioaccumulation of microplastics in the marine biotas, including fishes, occurs through the food chain. Microplastics enter the fish body through their gills and mouth. Contamination of microplastics inside the fish body can cause several effects, such as increasing toxicity effect, and growth inhibition. This research analyzed the form and amount of the microplastics found in each gill and gastrointestinal tract of the fish samples. A total of 15 samples of cantang grouper were taken from the floating net cage near Kampung Peres, Pulau Panjang. Samples were transported to the laboratory using an icebox. The gill and gastrointestinal tract of samples are isolated from their body, then destructed with HNO3 65% for 24 hours. After 24 hours, the samples were mixed with the concentrated NaCl solution with a ratio of 1:4. Microplastics form and amount are observed under the light microscope with three times repetition. The results show that the microplastics found in the gill and gastrointestinal tract of cantang groupers are mostly found in the form of fragments. The microplastics abundance in gills was 51893,33 ± 2594,67 particles/individual, and in the gastrointestinal tracts was 83926,67 ± 4196,33 particles/individual.

Cantang grouper (Epinephelus fuscoguttatus lanceolatus) is the result of hybridization between female tiger grouper and male grouper fish which is widely cultivated because it has fast growth, easy to breed, and lower cannibalism. Cultivation of cantang grouper can be carried out in semi-intensive ponds and floating net cages (KJA) which have the potential for grouper nursery and rearing activities. One of the problems in the cultivation of cantang grouper is the presence of disease attacks caused by marine leeches Zeylanicobdella with a prevalence of up to 100% in grouper culture in floating net cages. This study aims to determine differences in species and intensity of marine leech Zeylanicobdella infestation in cantang grouper (Epinephelus fuscoguttatus lanceolatus) from semi-intensive ponds in Brondong District, Lamongan and floating net cages (FNC) on Mandangin Island, Madura. The method used in this research is a survey and sampling is done by purposive sampling method. Cantang groupers measuring 15-20 cm from semi-intensive ponds and 20-25 cm from floating net cages each were taken as many as 35 individuals. Identification of Zeylanicobdella marine leeches using a binocular microscope and making sketches of ectoparasites with the help of a binocular microscope equipped with a lucida camera. Marine leech species found to infest the cantang grouper (Epinephelus fuscoguttatus lanceolatus) is Zeylanicobdella arugamensis which was found on the body surface, fins, gills, and eyes. The results of statistical analysis using the Mann-Whitney U test showed that there was no significant difference (p>0,05) between species and intensity of Zeylanicobdella arugamensis in cantang grouper reared in semi-intensive ponds and floating net cages. The intensity of marine leeches Zeylanicobdella arugamensis in semi-intensive ponds was in the medium category (14,74 individuals/head) and in floating net cages was in the medium category (27,74 individuals/head). The highest intensity of infestation marine leeches Zeylanicobdella arugamensis in floating net cages of 27,74 individuals/head. There was no significant difference in the intensity of Zeylanicobdella arugamensis marine leech infestation in cantang grouper both from semi-intensive ponds and floating net cages (FNC) which were included in the medium category.
