Abstract

This study was carried out in March-April 2024 in the intertidal zone of Bukit Batu District, Bengkalis Regency, Riau Province, to know the size distribution and the relationship between sediment organic matter content and the abundance of Cerithidea obtuse. This research uses a survey method by determining sampling stations using purposive sampling of three stations. Each station has three transects consisting of plots measuring 3 m2. The Kruskal-Wallis test was carried out to determine differences in abundance and the relationship between sediment organic matter content and the abundance of C. obtuse. Statistical correlation and linear regression tests were carried out. The results showed that the organic matter content of the sediment is included in the medium-high category, ranging from 15.01%-20.77%. The abundance of C. obtuse ranged between 5.12−6.96 ind/m2. There were differences in the abundance of C. obtuse among stations, with details between stations 3 and 1 and stations 3 and 2 being significant, while between stations 1 and 2 it was not significant. There were no differences in the abundance of C. obtusa among intertidal subzones. The distribution of C. obtuse is clustered with a dominant size of 20.7−34.5 mm. There is a moderate relationship between sediment organic matter content and the abundance of C. obtusa with a correlation coefficient (r) of 0.573, which is interpreted in the equation Y = 0.353X + 12.146.

Abstract

Waters in Parit Keladi Village have potential fish resources that cannot be developed due to household and agricultural waste contamination. This study aims to analyze water quality and plankton composition in the waters of Parit Keladi Village for freshwater fish farming. The study used a survey method in three locations, namely waters upstream, around residential areas, and downstream. Water quality parameters analyzed were temperature, depth, brightness, salinity, IDS, DO, BOD, COD, ammonia, nitrite, and nitrate. Plankton species, density, and biological index were analyzed. The results showed that the three locations' temperature, salinity, brightness, IDS, DO, COD, ammonia, nitrate, and nitrite met the national water quality standards for freshwater fish farming. However, BOD and depth values still did not meet the standard values. Planktons found consisted of 29 phytoplankton species and I zooplankton species with a total density of 9,350x103 cell/mL at location I, 9,540x103 cell/mL at location II, and 8,300x103 cell/mL at location III. The level of diversity was low, with the dominance of Chlorella vulgaris and Chroococcus species. It is concluded that water quality and plankton composition in the waters of Parit Keladi Village still need to be managed to develop freshwater fish farming

Abstract

Striped catfish (Pangasianodon hypopthalmus) is well known in Asia, specifically in Southeast Asia, such as Vietnam, Thailand, Indonesia, Malaysia, Cambodia, Burma, and Brunei Darussalam. Currently, catfish have been exported to almost all countries in the world. This study aims to analyze the chemical composition of processed catfish by-products and find alternatives for their economic utilization. The research method used is the experimental method, namely conducting experiments on using processed by-products of catfish as food raw materials. Furthermore, quality analysis was performed on processed by-products and raw food materials, namely proximate analysis and amino acid profile. Proximate analysis of processed catfish by-products (meat attached to bones, belly fat, fish bones, and offal) includes protein, fat, water content, carbohydrates, and amino acids. These by-products are still classified as functional. Therefore, this research utilizes these by-products in food raw materials. The chemical analysis (proximate) results of the products produced showed numbers that meet SNI quality standards as food products. By-products of catfish processing (fillets and smoked catfish) can be utilized as food raw materials in the form of fish concentrate flour, fish bone meal, and fish oil.

Abstract

Snakehead fish (Channa maruliodes) is a freshwater fish that is increasingly popular among ornamental fish enthusiasts, especially because of its beautiful colors. Color brightness is an important factor in the culture of snakehead fish. This study aims to evaluate the effect of astaxanthin addition on increasing the color brightness of snakehead fish. This study used a completely randomized design (CRD) experimental method consisting of 4 treatments with 5 replications. The treatment used was the addition of Astaxanthin (AST) with doses of 0% (AST0), 1% (AST1), 3% (AST3), and 5% (AST5). The snakehead fish used had a weight size between 30.4-30.8 g/individual. The parameters measured in this study were the increase in color brightness, growth, feed conversion and efficiency, and the quality of the maintenance media. The results showed that the addition of astaxanthin in the feed had a significant effect on the level of color brightness, growth and feed utilization of snakehead fish (P <0.05). The best addition of astaxanthin was obtained in the AST5 treatment with a TCF value of 5.17, total carotenoids (136.68 ppm), absolute weight (23.00 g), absolute length (3.10 cm), specific growth rate (78.00%), feed conversion (4.35), and feed efficiency of 23.00%. These findings indicate the potential of astaxanthin in improving the quality of catfish culture.
