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

Nemo fish cultivation activities at BPBL (Balai Perikanan Budidaya Laut) is located in West Sekotong, West Lombok Regency, West Nusa Tenggara. It is one of the technical implementation units for marine aquaculture in developing marine fish farming activities such as ornamental nemo or clown fish. The purpose of this activity is to determine the spawning of nemo fish carried out on an aquarium scale. Clown fish spawning activity at BPBL Lombok produces up to 1,050 eggs in a period, but the average fertilized is 1,012 eggs, and the hatching numbers are 884 eggs during 6 days of incubation and the time needed to start hatching is 24 hours. Some of the parameters of larval growth from eggs, namely FR / Fertilization Rate, get a result of 96%, HR (Hatching Rate) gets a value of 87%, SR (Survival Rate) with a value of 92%. Water quality such as the ideal temperature in nemo fish cultivation is in the range of 27-32°C, while the ideal pH is 6.7-8.8. Dissolved oxygen is more than 5 mg/L. The salinity and ammonia content obtained are ideal, which showing value 30-34 ppt for salinity and ammonia levels less than 3 mg/L.

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.

Abstract

Abalone is a seafood commodity with high economic value, because it is a food that is rich in protein and has aesthetic value in its shell. Market demand continues to increase in several Asian countries. The majority of the abalone industry still relies on natural products, resulting in continued exploitation of abalone. Abalone cultivation is the right choice to prevent extinction due to exploitation. One of the cultivation activities is raising abalone seeds, so this activity aims to understand the management of raising abalone seeds (Haliotis squamata) so that they produce quality seeds. This activity was carried out from March 13th until May 6th 2024 at BPBL Lombok, Sekotong. Data collection techniques use secondary data and primary data. Abalone seed rearing management includes several stages, including preparation of rearing tanks, namely cleaning fiber tubs and sterilizing the tubs, spreading seeds 1-2 cm in size, 2 months old with a density of 500 fish/basket, management of feeding Gracilaria sp., Sargassum sp. and Ulva sp. given ad libitum, the results of measuring the growth of abalone seeds have increased with absolute weight growth of 2.87 gr, absolute length growth of 0.59 cm, and SGR growth of 1.04 % per day, as well as seed SR value of 95.7 %, water quality management and checking water quality parameters during maintenance and handling pests that can attack abalone seeds.

Abstract

Barramundi (Lates calcarifer) is a high economic commodity that has euryhaline properties. The maintenance of barramundi larvae is quite crucial in its cultivation efforts. This study aims to determine the survival rate of barramundi during maintenance at the Balai Besar Riset Budidaya Laut dan Penyuluhan Perikanan (BBRBLPP) Gondol, Bali. The activity lasted for 35 days, observing the parameters of larvae development, type and variety of feed, and water quality. The feed used consisted of natural feed such as Rotifera sp., Nanochloropsis sp., and Artemia sp., as well as artificial feed in the form of PSP and KAIO 3. Feeding was carried out gradually according to the age of larvae with adjusted frequencies and doses. The results showed that larvae showed progressive morphological and behavioral development from day 0 to day 27. The survival rate achieved was 79% of the total 40,000 larvae released, far exceeding the SNI standard (20%). Water quality during maintenance was within the optimal range. Additional efforts such as adding probiotic, daily siphoning, and water changes contributed to successful rearing. These results demonstrate that the combination of good feed and optimal water quality management significantly influences the success of barramundi larval cultivation. This study provides an important foundation for the development of efficient and sustainable large-scale barramundi cultivation.
