Abstract

Food and feeding habits are important things in bioecological of fish. This study provides an understanding of the feeding habits and intensity of the M. gulio, by analyzing its food composition, relative gut length (RGL) and gastro-somatic index (GaSI). Fish specimens were caught with a gill net and fishing rod in an area of Cianjur estuaries during a period of one year from October 2021 to September 2022. The analysis of 452 fish samples shows that the relative gut length (RGL) values revealed the feeding habit of M. gulio as carni-omnivorous. The GaSI value was used to determine feeding intensity and was found to be highest in November, at Cidamar estuary, and in the second size group (7.1-10 cm). These results provide new knowledge on this fish species’ feeding habit and intensity, which also helps understand the fish adaptation and conservation in the study area.

Abstract

 The mangrove ecosystem of Cemara Kulon Village has the potential for fishery resources which has decreased in line with various anthropogenic activities. This study aims to determine the composition of fish and analyze the status of the fish community structure and its relation to the physical-chemical aspects of the waters in the mangrove ecosystem of Cemara Kulon Village. This research was conducted over a period of three months  in the mangrove ecosystem of Cemara Kulon Village. The method used in this research was  descriptive quantitative purposive and composite sampling at 3 research stations. Parameters observed in this study were relative abundance, diversity, uniformity, dominance, and the relationship between community structure and aquatic physico-chemical parameters. During the study, 508 fish were caught, consisting of 20 species from 16 families. The value of diversity was in the moderate category with a ranged of 1.87-2.50; the uniformity value was in the moderate category with a ranged of 0.41-0.46 and the dominance value was in the low category with a ranged of 0.11-0.22.   Based on the results of the Canonical Correspondence Analysis (CCA) revealed that fish diversity was affected by light transparency and DO, the uniformity of fish was  affected by temperature, and the dominance of fish was affected by ammonia. The fish community structure was categorized as unstable which was influenced by water quality.

Abstract

This research aims to examine the effect of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin on the survival and growth of common carp (Cyprinus carpio). The study was conducted from September to October 2022 at the Ciparanje Inland Fisheries Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used was an experimental method, and the experimental design employed was a completely randomized design (CRD). The study included six treatments with three replications. The test fish used were Majalaya strain common carp fingerling, measuring 7-8 cm, obtained from the Cibiru Fish Seed Center in Bandung City. The treatments examined in this study were Treatment A (0 ppm), B (12.8 ppm), C (25.6 ppm), D (38.4 ppm), E (51.2 ppm), and F (64 ppm). The insecticides were administered once at the beginning of the research in the water, which served as the maintenance medium, according to the treatment concentrations. The parameters observed were survival rate, growth, and water quality. Observations were conducted for 28 days after the application of the plant-based insecticides. The highest percentage of survival was found in Treatment A (control) at 100%, while the lowest percentage of survival was observed in Treatment F (64 ppm) at 81.7%. The highest absolute length growth was recorded in Treatment A (control) at 2.73 cm, and the lowest absolute length growth was observed in Treatment F (64 ppm) at 1.97 cm. The highest weight growth was observed in Treatment A (control) at 4.2 g, and the lowest absolute weight growth was found in Treatment F (64 ppm) at 2.6 g. The research indicates that the growth and survival of common carp fingerling (Cyprinus carpio) decrease due to the influence of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin.
