Abstract

The Dog conch is an important marine biota for ecology; besides that, it has economic value with high nutritional content. The purpose of this study was to analyze the density of the dog conch, to determine the appropriate environmental parameters for gonggong snails restocking, and to analyze the suitability of the location for the dog conchrestocking in Kelabat Bay, Bangka Island. This research was conducted from March to April 2021. The data collection of the dog conchand sea grasses used purposive sampling method. The highest density of the dog conchwas at station 7 with a density of 2000 (Ind/ha), while the lowest densities of the dog conchwere at stations 1, 4, 5 and 9 because dog conch was not founded. The results of the suitability of aquatic environmental parameters are categorized as still suitable for the life of gonggong snails. The suitability index values for the location of the the dog conch restocking at stations 6, 7, 8, 9 and 10 had values above 84-89 which is categorized as very suitable, while at stations 1, 2, 3, 4, 5 with values above 75-78 were categorized as appropriate. The results of the study indicate that the waters of Kelabat Bay have certain areas that are ideal to be used as a location for the dog conch restocking, so the recommended location for Dog Conch restocking is in the outer Kelabat Bay while still paying attention to sustainable fishing efforts.

Abstract

The Coastal Area is an aquatic ecosystem that has high productivity and is able to support the survival of various aquatic biota and is often used as a place for various daily life activities by residents including fishing activities, tourism activities and mining activities. The aims of this study were to analyze the density, diversity, uniformity and dominance of molluscs (gastropods and bivalves) and to analyze the relationship between the density of mollusks (gastropods and bivalves) and environmental factors. The sampling technique used the 1x1m² Quadratic Transect method. The results obtained at all observation stations were 13 types of gastropods and 9 types of bivalves. Diversity is in the low to medium category which ranges from 0.8760 to 2.1655. The uniformity of gastropods and bivalves was moderate to high which ranged from 0.5291-0.8715, and was dominated by Pinerella cingulata gastropods. The results of principal component analysis (PCA) showed that the density of gastropods showed the parameters of depth, silt and clay, and the density of bivalves showed the parameters of brightness, salinity and sand which had a high affinity with density which was a limiting factor for the distribution or abundance of gastropods and bivalves.

Abstract

White Leg shrimp have a non-specific immune response that can be seen in granular cells and hyaline cells. To support an excellent white-leg shrimp immune response, providing an immunostimulant in the form of docosahexaenoic acid (DHA) is necessary. This research activity aims to determine the percentage of granular and hyaline cells in white-leg shrimp and the immune response of white-leg shrimp. This research was carried out in April 2022 at PT. Emas Sempurna Anugrah, Bangka Belitung. This type of research is descriptive qualitative. There are five ponds studied with different pond sizes and stocking densities. The results showed that the percentage of granular cells is higher than hyaline cells, with an average percentage of granular cells is 57.27%, while the average percentage of hyaline cells is 42.73%. The average THC value is 5,730,000 cells/ml, indicating that the white-leg shrimp's immune response is good but has fluctuating value. The white-leg shrimp's immune response in the pond shows inconsistent results due to external factors such as water quality and bad weather.

Abstract

Batu Belubang Fish Landing Base (PPI) is one of the PPI in Central Bangka whose fishery business activities are still running today. However, local fishermen still lack information about the protection status and lack of data on the status of these fish species. The lack of data makes fishermen overfisher. Therefore, this study was conducted to identify the species of fish landed at PPI Batu Belubang, classify the fishing gear used by Batu Belubang fishermen and determine the conservation status of the species of fish landed. Data collection will be carried out in March-April 2023 at Batu Belubang PPI. This study used survey and observation methods with qualitative descriptive data analysis. The results showed that there were 12 families identified, namely Carangidae, Clupeidae, Engraulidae, Scombridae, Sphyraenidae, Terapontidae, Ariidae, Leiognathidae, Nemipteridae, Siganidae, Synodontidae and Loligonidae. The classification of fishing gear used by fishermen is lift nets (boat charts and floating charts) and fishing rods. Conservation status based on IUCN found 12 species classified as Least Concern, one species Near Threatened, two species Data Deficient and four species Not Evaluated. Based on the results, it can be concluded that the sustainability of fisheries, especially endangered species, requires management by relevant stakeholders such as socialization from fisheries extension workers regarding conservation status and species of fish that are already endangered.

Abstract

Taxonomically, according to the World Register of Marine Species (WORMS), in 2021 the naming of the species Cymodocea serrulata will change to Oceana serrulata (R. Brown) Byng & Christenh. Many studies have been carried out in the Province of the Bangka Belitung Islands, but this type of distribution map has not been presented in detail. Observation of seagrass in the field allows the identification of seagrasses with other types of seagrass. This study aimed to identify morphology, species distribution, and other types of seagrass often associated with seagrass species Oceana serrulata in the Province of the Bangka Belitung Islands. The methods in this study include data collection, identification, and map making. Morphological identification of seagrass species refers to several identification sources. The distribution map of Oceana serrulata is presented from the seagrass data collection that has been carried out. This research uses data from different times, the first was obtained from 2011 and 2022 as primary data. The results of the study explain the identification carried out on the Oceana serrulata has the same characteristics as identification literature. Similarities seen from the identification of leaf morphology which ribbon curved like, parallel leaf veins and triangular shaped sheaths. Other seagrass species that are most often associated with Oceana serrulata are Halodule uninervis and Enhalus acoroides. The map of the distribution of seagrass species Oceana serrulata is found on the islands of Bangka, Belitung, Anak Air, Lepar, Ketawai, Semujur, Kalimambang, Kelayang, Kepayang, Ruk, and Sebongkok islands.
