Abstract

Gastropods are marine biota found in the waters of Pulau Terkulai, Tanjungpinang City and are one of the catch of fishermen. However, information on the structure of the gastropod community in these waters is not widely known. The purpose of this study was to determine the types of gastropods, gastropod community structure, and the relationship between gastropod community structure and environmental parameters in the waters of Terkulai Island. This research was conducted in April-August 2023. Determination of sampling points using random sampling method as many as 30 points with sampling plots measuring 1x1m2. The results of this study obtained 650 individuals with 15 species of gastropods. The highest density was found in Batillaria attramentaria species with a total of 12.20 ind/m2. Gastropod community structure diversity value (H') ranged from 1.512 which is classified as moderate. The uniformity value (E) ranges from 0.558 which is classified as moderate and the dominance value (D) ranges from 0.353 which is classified as moderate. The results of the measurement of the physicochemical parameters of the waters are still at a feasible threshold for gastropod life. The principal component analysis (PCA) shows that the density with water parameters has a positive correlation with temperature and organic matter.

Abstract

Pangkil Village is one of the areas located on the coast of Bintan Island, Teluk Bintan District. This island has an aquatic ecosystem with abundant marine resources, one of which is the mangrove ecosystem. Mangroves are the main supporting ecosystem for life activities in coastal areas that play an important role in maintaining the balance of environmental biological cycles. This study aims to determine the condition, distribution and density level of mangroves in the waters of Pangkil Village. This research was conducted in February-March 2021. The research method is purposive sampling, which means that the research station points are chosen intentionally based on the consideration of the condition of the existence of mangroves or the density of mangroves. The research station points were determined as many as 8 stations, at each station consisting of transects and at each transect consisting of 3 sample plot plots (Transect Line Plot). The density level data was collected using a line transect measuring 10x102 which was drawn from the sea to the land and the distribution of mangroves using lansat-8 imagery. The level of mangrove density in the waters of Pangkil Village is still quite good. The results of the research on the level of mangrove density in the waters of Pangkil Village are classified as good with the distribution of mangrove areas in the waters of Pangkil Village covering an area of 40.23 ha, with an average density level of 1,033 ind/ha per station to 1,733 ind/ha. with medium and solid status based on the Decree of the Minister of the Environment No. 201 year 2004.

Abstract

Business Crab (Portunus pelagicus) Kawal Village waters are waters located in the Gunung Kijang area, Bintan Regency, Riau Islands Province. High market demand for crab fishery commodities that triggers excessive exploitation so that it can have an impact on the sustainability of crab resources. This study aims to determine the condition of the sex ratio and the pattern of crab growth in the waters of Kawal Village, Bintan Regency. The method used in this study is a survey method. The sampling technique was carried out using a random census, in which the researcher immediately went down to the field to take a sample of 176 crabs. The results showed a good sex ratio for female crabs at 52% and male crabs at 48%, which has calculated the Chi-square test which between females and males has a balanced ratio, which results in: X2 count of 33, 2 while X table is 74,975 which if X2 count < X table: male and female sex ratio is balanced. The growth pattern of both female and male crabs in the waters of Kawal Village, Bintan Regency has a negative allometric character where the growth pattern of carapace width is greater than weight growth.
