Abstract

The presence of microplastics in the waters is due to plastic garbage that is difficult to decompose. Tilapia that live in the water has a high tolerance for polluted environments, thus making them vulnerable to microplastic contamination. The most common type of microplastic found in water is polyvinyl chloride. The study aims to investigate the effects of microplastic exposure on Tilapia growth and survival. The research plan used a complete random design (CRD) with four treatments and three repetitions. Exposure to microplastics in fish is carried out through feeding, with doses: without microplastic addition; addition of 0.01 mg per 0.75 g of feed; addition of 0.1 mg for 0.75 g of feeding; and addition of 1 mg for every 0.75 grams of feed. The mixed microplastic feed was given three times a day at a dose of 5% of the fish's body weight. Growth and survival data are analyzed using Anova; if there is any real impact, then further testing is done using Duncan. The study's findings showed that adding microplastics to specific weight growth, absolute weight, absolute length, feed conversion ratio, and survival at a dose of 1 mg per 0.75 g of feed was significantly different from treating the animals without adding microplastics. Therefore, we can conclude that a dose of 1 mg per 0.75 g of feed will impact the growth and survival of tilapia.

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

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

Natural feed is fish feed that has the form of microscopic organisms found in waters. Commonly used natural feeds are phytoplankton, zooplankton, protozoa, microcrustaceans, microscopic invertebrates, and others. The need for natural feed is growing in line with the increasing fisheries cultivation efforts. Phytoplankton has a very important role in waters, its ecological function as a primary producer and the beginning of the food chain causes phytoplankton to often be used as a measure of the fertility of waters. One of the phytoplankton that is abundant in waters because of its ability to survive even in extreme conditions and has a fat content is Nitzschia sp., a member of the Bacillariophyceae class. Nitzschia sp. plays an important role as a primary producer and is widely used as natural feed for marine organism larvae such as crustaceans, bivalves, and fish. The purpose of this study was to determine the laboratory-scale Nitzschia sp. natural feed culture technique to support cultivation activities. This research was conducted from March to April 2024 at the Marine Aquaculture Center (BPBL) Lombok, West Sekotong, West Lombok Regency, West Nusa Tenggara. The research methods used are descriptive methods and field observations (surveys). The results that the laboratory scale Nitzschia sp. natural feed culture technique includes equipment sterilization activities, culture preparation, seed distribution, density calculation and harvesting. Factors that affect the growth of Nitzschia sp. are culture media that are free from contamination, initial stocking density, light intensity of 2000-5000 Lux, water quality (pH, salinity, and temperature).
