Abstract

The larval stages in vannamei shrimp can be referred to as vulnerable stages that are prone to experiencing environmental crises, mainly due to the inadequate availability of food. Chaetoceros sp. is commonly used as a natural food source because it contains high nutrition that fulfills the larva's requirements for survival. However, the lack of proficiency in proper culture techniques impacts the success of cultivating Chaetoceros sp. as natural food. The objective of this study is to understand the culture techniques and challenges in cultivating natural food and to assess the effects of feeding Chaetoceros sp. on vannamei larvae (Litopenaeus vannamei). The data obtained in this study were analyzed descriptively, meticulously presenting the findings in a clear manner. In laboratory-scale Erlenmeyer culture, the peak plankton growth reached 15.3 million cells/mL, whereas in the Carboy, the density reached up to 5.1 million cells/ml. On the intermediate scale, plankton growth started at 550,000 cells/ml on the first day and increased to 1.8 million cells/mL on the eighth day. The effect of feeding Chaetoceros sp. as natural food source for vannamei larvae resulted in meeting the nutritional needs for the shrimp's body, contributing to the larval development with a relatively high survival rate of approximately 85%.

Abstract

Vaname shrimp (Litopenaeus vannamei) is a fishery commodity that is the largest contributor to exports compared to other commodities. The success of shrimp survival and growth cannot be separated from the molting process, which requires calcium. The calcium that absorbed from the cultivation media can play a greater role in the process of exoskeleton formation. Dolomite lime (CaMg(CO3)) and tohor (CaO) can be sources of calcium that can be added to cultivation media. The research method used in this study was a completely randomized design (CRD) consisting of 5 different treatments (A: without additional lime, B: 0.8 gr dolomite, C: 0.8 gr tohor, D: 0.3 gr dolomite + 0.5 gr of tohor, E: 0.5 gr of dolomite + 0.3 gr of tohor) with 3 repetitions. The results showed that the addition of lime at different doses provided a molting frequency ranging from 2.07 – 3.23 times during the 60 days rearing period, where treatment E was the optimum treatment. The absolute weight growth obtained ranged from 2.52 gr – 5.03 gr, with an absolute length of 5.25 cm – 9.11 cm. The highest survival rate during maintenance in treatment E reached 72%. The water quality conditions measured during the activity were alkalinity 135 – 146 ppm, Ca hardness 132.74 – 172.39 ppm, temperature 29.9 – 30.3°C, DO 6.3 – 6.5 mg/l, pH 7 .9 – 8.3 and salinity 32 -34 ppt.

Abstract

Microplastics have become a major concern in global environmental research due to their significant impact on marine ecosystems. Microplastic pollution has been detected in almost all aquatic environments, including oceans, rivers and lakes. This study aims to evaluate the level of microplastic contamination in the digestive organs of old parrot fish caught in Ekas Bay. Focusing on the digestive organs is important because ingested microplastics can have detrimental effects on fish health, including digestive disorders and bioaccumulation of harmful chemicals. The research method used was descriptive with a sample size of six parrot fish. Based on research conducted on the digestive organs of parrot fish, it was found that the types of microplastics found were in the form of fragments, films, pellets and fibers. The total abundance of microplastics in the intestinal organs ranges from 290 par/gr to 410 par/gr, while in the stomach organs it is 272 par/gr to 310 par/gr. The highest percentage of microplastics in the intestinal organs was pellets at 47% and in the stomach organs it was fragments at 54%.

Abstract

This study investigates microplastic contamination in whiteleg shrimp (Litopenaeus vannamei) cultivation systems, focusing on water, feed, and shrimp health. Microplastics, which pose significant threats to aquaculture, are often ingested by shrimp, potentially causing physiological damage and reducing product quality. The research was conducted from June to September 2024 at PT—X in North Lombok Regency. Samples of water, shrimp organs (intestines, stomach, and gills), and feed (pellets and crumbles) were analyzed for microplastic contamination. Results revealed a high presence of microplastic fragments in both shrimp and feed, with a significant reduction in microplastic particles after water filtration treatment. Specifically, the water reservoir contained 71 microplastic particles before treatment, with fragments being the most prevalent, and decreased to 8 particles post-treatment. The pelleted feed showed 102 microplastic particles, with fragments comprising 90 of them. Similarly, crumble feed contained 49 microplastic particles, predominantly fragments. The findings emphasize the significant role of microplastic pollution from the surrounding environment and the feed production process in shrimp farming. This study provides essential insights into the sources and impact of microplastics on shrimp health and the quality of aquaculture products, advocating for improved management practices and environmental awareness to mitigate contamination risks.
