“…Rational and appropriate fisheries management approaches are required to maintain the grouper stocks of Kwandang Bay. Formulating such measures requires up-todate and valid data on the population dynamics of the target stocks (Suradi et al 2017;Sabrah et al 2018;AbouelFadl and Farrag 2021). Key population dynamics parameters include growth, mortality, exploitation rate, and recruitment (Kirubasankar et al 2013;Mehanna et al 2013;Sabrah et al 2015;Ramachandran and Ramalingam 2020).…”

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.

“…Tirtadanu and Anthony (2018) reported that the size of white shrimps in Kaimana, West Papua were 25-49 mm, which was considered small for its population. Other studies by Suradi et al (2017) also found small individuals of white shrimp in the northern coast of West Java and the coast of Penyu Bay, respectively. Another indication of the size dominance was the harvesting preference on certain sizes by fishermen, which left the smaller shrimps in the environment (Suman and Umar 2010).…”

Population of white shrimp (Penaeus merguiensis) in a mangrove ecosystem, Belawan, North Sumatra, Indonesia

Abstract. Widiani I, Barus TA, Wahyuningsih H. 2021. Population of white shrimp (Penaeus merguiensis) in a mangrove ecosystem, Belawan, North Sumatra, Indonesia. Biodiversitas 22: 5367-5374. White shrimp (Penaeus merguiensis De Man) is an essential fishery commodity with high economic and ecological value in the coastal area of North Sumatra. The main objective of this study was to determine the density of white shrimp in each harvesting area and to evaluate the current physicochemical factors in the Belawan mangrove ecosystem, North Sumatra, Indonesia. Four sampling sites were chosen as study areas. White shrimps were caught using ambai nets with a dimension of 4.5×4.5 m in width and 17 m in length placed from 4:00 - 7:00 PM. Measurement of physicochemical characteristics of sampling sites was conducted in situ and in the laboratory. Based on our study, the highest shrimp density was documented in the fishpond area (station 1) (89 ind/m2), while the lowest density was from the mangrove ecosystem area (station 2) (28 ind/m2). Based on the length class, the population of white shrimps was dominated by 16-18 mm shrimps. The gonad maturity level of the white shrimp population was classified into level 1 (The absence of thin-to-thick threads along the dorsal lining indicated the lowest gonad maturity level). White shrimps exhibited negative allometry in growth with a clumped pattern in population dispersion within the study area. The physicochemical parameters in four sampling sites, such as phosphorus content (P), and nitrate (NO3), exceeded the standard national quality set by the Ministry of Environment and Forestry.

“…Although this analytical method has not been explicitly tested for shellfish, it has been used to infer growth patterns in finfish (e.g., Scharf 2000; Olsen 2019b), and similar length‐based methods have been used for some shellfish species (e.g., Pauly 1987; Etim and Sankare 1998; Surandi et al. 2017).…”

Seasonal Abundance and Length Patterns of Brown and White Shrimp in Texas Estuaries and Nearshore Waters: Implications for Population and Fishery Dynamics

2022

Penaeid shrimp are a major contributor to commercial landings in the Gulf of Mexico, with white shrimp Litopenaeus setiferus and brown shrimp Farfantepenaeus aztecus making up the bulk of the landings off Texas. In this study, we examined seasonal trends in white and brown shrimp population demographics (relative abundance, monthly proportion of catch, and length) and their relationship with water quality parameters (water temperature and salinity) across a 36-year fisheryindependent data set for Texas estuarine and nearshore waters. The primary findings of this analysis were consistent negative trends in seasonal mean TL (April-August) for brown shrimp. These negative trends resulted in decreases in mean TL of up to 20 mm across the time series. Additionally, growth coefficients calculated on an annual scale for brown shrimp showed negative trends as well. White shrimp did not show the same consistently negative trends in mean length or growth. Although expected seasonal trends in CPUE and monthly proportions of catch were observed, the analysis showed few convincing or consistent annual trends in these metrics for either species. We suggest that the differing trends in mean length (i.e., between species) may be explained by summer water temperatures exceeding the optimum growth range for brown shrimp in the latter part of the time series examined here. Such trends in mean length for the brown shrimp population may have implications for population fecundity and may affect the value and efficiency of shrimp harvest in commercial fisheries, though this has yet to be seen. Nevertheless, managers should remain vigilant to any continued negative trends in brown shrimp length and their potential impact on the population and fishery dynamics.
