Abstract. Achmad DS, Gani S, Ardiansyah W, Mokoginta MM, Nurdin MS, Jompa J, Indrianti MA, Achmad N. 2022. Population dynamics of reef fish in the Kwandang Bay, Sulawesi Sea, Indonesia. Biodiversitas 23: 5217-5226. The grouper stocks in Kwandang Bay, Sulawesi Sea, Indonesia, are dominated by orange-spotted grouper (Epinephelus coioides) and coral trout (Plectropomus leopardus). However, the Kwandang Bay grouper fishery is currently experiencing serious challenges due to population decline resulting in a decline in both the average size of fish caught and the production volume. This study was conducted in Kwandang Bay, Sulawesi Sea, from January to December 2021. The population dynamics parameters estimated were growth, recruitment, mortality, exploitation rate and yield per recruit. The results showed that the total length (TL) of E. coioides and P. leopardus ranged from 16.50-101 cm and 17.90-60 cm, respectively, with Von Bertalanffy K-coefficients of 0.38 and 0.69, respectively. Recruitment occurred during most of the year, with respective recruitment value ranges of 0.99-17.11% and 0.08-19.22%. Natural and fishing mortality was 0.69/year-1 and 0.87/year-1 for E. coioides, 1.16/year-1 and 1.47/year-1 for P. leopardus. Beverton and Holt yield per recruit analysis indicated recruitment overfishing of both E. coioides and P. leopardus. Fishing regulations are needed to maintain a sustainable grouper fishery, including a 25% reduction in fishing vessels and gear, to enable the groupers of Kwandang Bay to spawn at least once during their life cycle.

“…Laju eksploitasi yang melebihi nilai Emax menyebabkan terjadinya penurunan rekrutmen populasi di perairan (Achmad et al, 2022;Azmi et al, 2022). Hal ini yang menyebabkan nilai SPR pada lobster dibawah 20% karena populasi lobster yang siap mijah di alam berkurang.…”

Currently, spiny lobster fishery in Indonesia ranks third as an export commodity from the crustacean subphylum after shrimp and blue swimming crab – mud crab. Most of the spiny lobster export needs still rely on wild population resulting in fishing pressure. To ensure the sustainability of spiny lobster stocks, information of the Spawning Potential Ratio (SPR) is needed. This study aims to analyze SPR of spiny lobsters of Panulirus femoristriga and P. versicolor species. The research was conducted in May − November 2022 in Donggala Regency waters. SPR analysis uses the Length-Based SPR method. The results showed that the stock status of P. femoristriga and P. versicolor had experienced growth overfishing and recruitment overfishing with estimated SPRs of 17 and 11%, respectively. Fishing regulations are needed to maintain a sustainable spiny lobster fishery through increased participation of stakeholders in the implementation, monitoring and evaluation of the regulations set by the government. In addition, it is necessary to reduce of efforts 27 − 33% from the current exploitation rate to E50 0.28.

“…Abundant mangroves play an important role as a nutrient source for the surrounding area, preventing erosion, and filtering sediment during the fall period (Mitra 2020). The mangrove ecosystem is an ideal habitat for spawning and feeding communities such as Crustacea, Gastropoda and Bivalvia (Azmi et al 2022;Isroni et al 2023;Mawardi et al 2023). Bivalves and crustaceans share similar habitats with similar characteristics in coastal areas covered by mangrove (Islamy and Hasan 2020;Setyadi et al 2021).…”

Abstract. Mawardi, Sarong MA, Suhendrayatna, Irham M. 2024. The relationship between crustacean diversity and population dynamics of Blood Cockle Tegillarca granosa in the coastal area of West Langsa (Aceh Province, Indonesia). Biodiversitas 25: 690-699. Coastal areas serve as a transitional zone between land and sea, influenced by tidal fluctuations and river estuary currents. Coasts are ideal habitats for spawning and nurturing various crustaceans and bivalves. The aim of this study is to determine the relationship between the Shannon-Wiener diversity index of crustaceans and population dynamics of Tegillarca granosa (Linnaeus, 1758) (Arcidae, Bivalvia) in three different locations. The study utilized a survey method with sampling conducted using transects from the coastline towards the land in coastal areas covered with mangroves, employing transects measuring 5 meters by 5 meters. All samples collected at the study locations were fixed for identification. A total of 1,583 Crustacea individuals belonging to 17 species were sampled. The Shannon-Wiener diversity index of crustaceans ranged from 1.99 to 2.31, categorized as moderate. The highest number of individuals of T. granosa was in November, while the lowest number of individuals was recorded in July. Males of T. granosa were more dominant than females across all study sites. There was a positive correlation between the crustacean diversity index and T. granosa specimens, but a negative correlation with the crustacean dominance index. Seawater salinity, showed a positive correlation with crustacean diversity and the population dynamics of T. granosa.
