Abstract

This study investigates the abundance and diversity of bacteria associated with two intertidal seaweeds, Sargassum sp. and Kappaphycus alvarezii, in Ekas Bay. Intertidal zones are dynamic environments where seaweeds and their associated microbial communities play crucial roles in ecological processes. Seaweeds host a variety of bacteria that contribute to nutrient cycling, seaweed health, and overall ecosystem function. The primary variable measured in this study was the bacterial abundance, expressed as Colony Forming Units per milliliter (CFU/mL). The conclusion of these findings has positive implications for the environmental health around the floating raft, base stakes, Sargassum sp. and Kappaphycus alverazii. The absence of harmful bacteria supports the sustainability of aquatic ecosystems and can provide positive benefits for the species inhabiting those areas.

Abstract

Ekas Bay is a semi-enclosed bay and estuary in the southern part of Lombok Island. Ekas Bay has an area of 5,312.68 hectares, although it is not very wide, this bay has its own uniqueness and is relatively protected from waves because it is located inland. In Ekas Bay itself, two river estuaries are found, namely the Awang River Estuary and the Kelongkong River Estuary. The existence of these two river estuaries has a negative impact on the condition of the waters of Ekas Bay because residue from household activities is carried away by the river current, one of which is plastic waste. The presence of microplastics on ocean coasts has a negative impact on sea water quality and the life of marine biota, microplastics cannot evaporate or degrade by themselves, microplastics will accumulate in sea water and the body parts of marine biota. This research aims to identify the type and abundance of microplastics in the Ekas Bay floating net cage area and the results obtained in water samples were that the abundance of microplastics at point A was 49.44 par/L, point B was 55.76 par/L and point C was 40.40 par /L. The abundance of microplastics in sediment samples at point A was 12.25 par/L, point B was 10.8 par/L and point C was 11.01 par/L.

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

Hybrid cantang grouper is a type of grouper fish that is included in the luxury food commodity, namely a type of commodity that has a high selling value and is often exported which has an impact on increasing the need for seeds so that efforts are needed that culminate in seeding. The purpose of this study was to study and understand the seeding technique of hybrid cantang grouper (Ephinephelus fuscoguttatus x Epinephelus lanceolatus) which was carried out at the Brackish Water Aquaculture Center (BPBAP) Situbondo, East Java. The population of this study used 2 larval maintenance tanks and 14 natural feed tanks. Data were obtained directly through direct observation in the field. The results of the study showed that cantang grouper seeds were produced from the hybridization process, then the types of feed given during the larval maintenance period were natural feed (Rotifera, Artemia and Rebon shrimp) and artificial feed (Powder, crumbs and pellets), then air quality maintenance was carried out by giving Chlorella sp. as a green water system, then air changes, siphoning with air quality values ​​during the maintenance period of temperature 30oC, Salinity 30.1 ppt, pH 8.05, Nitrite 0.498 mg / L, Free Ammonia 0.04675 mg / L, DO 5.85 mg / L. The Hatching Rate (HR) value was obtained 98.45% and 92.63% and Survival rate 12.68% with a maintenance period of 70 days until the total harvest of 2.7cm-3cm seeds.

Abstract

Indonesia is a maritime country that has great potential in the fisheries sector, especially in cultivating vaname shrimp (Litopenaeus vannamei). Disease in vaname shrimp is the biggest factor causing cultivation failure, one of which is caused by IMNV (Infectious myonecrosis virus). The aim of this research is to study IMNV detection techniques in vaname shrimp using the PCR (Polymerase Chain Reaction) method at the Situbondo Brackish Water Aquaculture Fisheries Center. This research uses a descriptive method, with stages starting from necropsy, RNA extraction using the silica method, amplification using RT-PCR and Nested-PCR, to electrophoresis and documenting the results using UV documentation. The results showed that the PCR technique was effective in detecting IMNV in shrimp, with DNA amplification clearly visible through agarose gel electrophoresis. Documentation of PCR results indicated the presence of a DNA band in the IMNV positive sample, which corresponded to the positive control. In conclusion, IMNV detection using the PCR method at BPBAP Situbondo has proven to be effective for identifying disease in vaname shrimp and can be applied as an initial step in controlling disease in vaname shrimp cultivation.

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

Mud crab (Scylla serrata) is a fishery commodity that has high economic value and has a wide salinity tolerance so that its growth can be developed. The growth of mud crabs can be influenced by genetic traits such as moulting. In cultivation activities there are methods that can accelerate the moulting process such as environmental engineering (increasing and decreasing the salinity of the maintenance media) and mutilation. This study aims to determine the growth and fastest moulting time of crabs in media with different salinities in controlled media. The method used is an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications, namely: (Control), (P1: 5 ppt), (P2: 10 ppt), (P3: 15 ppt) and (P4: 20 ppt) which are given to mud crabs for 45 days. The results showed that at 5 ppt salinity obtained the fastest moulting time which was 24.3 days and the longest was at 20 ppt salinity for 39 days, while the highest growth was obtained in the 15 ppt salinity treatment with an average absolute weight of 27.3 grams and the lowest was in the control treatment with an average absolute weight of 18.3 grams.
