Disa Aulia Rahmi, Edwin Jefri, Nurliah Buhari, Hotmariyah Hotmariyah — Wed, 29 Jan 2025 00:00:00 +0800

Macroalgae are a group of lower marine plants commonly referred to as thalloid plants. The diversity of macroalgae in tropical regions, particularly in eastern Indonesia, is very high due to the area being part of the Wallacea region. This study aims to determine the level of diversity and distribution of macroalgae in these waters. The method used is the line transect method, with data analysis including ecological indices and distribution patterns. The results show that the diversity index ranges from 2.45 to 2.80, which falls into the medium category. The evenness index ranges from 0.80 to 0.81, classified as high, while the dominance index ranges from 0.09 to 0.11, which is considered low. The distribution pattern of macroalgae at stations 1, 2, and 3 ranges from 1.37 to 1.49, indicating a clustered distribution pattern. This suggests that the environmental conditions in the waters of Gili Air are stable and conducive to the growth of macroalgae, with no species dominating the ecosystem.

Cuttlefish are a fishery resource classified under the class Cephalopods. The potential for cuttlefish fisheries in Indonesia is quite significant, considering the country has vast and diverse marine waters. The demand for fishery products, including cuttlefish, both in domestic and international markets, continues to increase. Despite the great potential, sustainable management and protection of marine ecosystems are key to ensuring that the utilization of these resources does not harm the environment and can continue in the long term. Research on the species composition and biological aspects of cuttlefish is necessary to understand the condition of the aquatic ecosystem. Data collection was carried out using the accidental sampling method and direct surveys conducted. A total of 457 specimens were obtained during the study. Data analysis included species composition analysis, gender analysis, and the analysis of the length-weight relationship of cuttlefish. The result of this study shows that the captured cuttlefish consists of two species: Sepia latimanus and Sepia pharaonis. The number of males is higher than females; however, the ratio is approximately 1:1. Based on this result, the sex ratio is categorized as nearly balanced, with a ratio of 1:1. The length-weight relationship of all landed cuttlefish, specifically the two species Sepia latimanus and Sepia pharaonis, shows a negative allometric growth, where length growth is faster than weight growth. The purpose of this study is to determine the composition of the type, sex ratio and the relationship between the length and weight of the landed cuttlefish.

THE INFLUENCE OF STOCKING DENSITIES ON WHITE SHRIMP (Litopenaeus vannamei) REARED USING INTENSIVE SYSTEM: PRODUCTION PERFORMANCE AND WATER QUALITY

Wed, 29 Jan 2025 00:00:00 +0800

ABSTRACT

The increasing trend of vaname shrimp cultivation production encourages farmers to increase their cultivation production. The success of vaname shrimp cultivation can be seen from the ability to measure the capacity of shrimp biomass in maintenance activities and stocking density patterns based on the maximum capacity of the pond in each plot. The purpose of this study was to analyze vaname shrimp cultivation activities for a period of 2 years (2023-2024) in intensive system ponds based on different stocking density patterns at 140 shrimp/m² and 190 shrimp/m². This study was carried out for 6 cultivation cycles, each cycle was carried out for 100 days. The results of statistical tests showed that the shrimp stocking density pattern had a significant effect (p <0.05) on biomass, productivity, survival and feed conversion ratio. The average survival rate of 140 shrimp/m² stocking density was 85.33%, biomass was 3,327.75 kg, FCR was 1.44 and productivity was 30.8 tons/ha. The average survival rate with a stocking density of 190 shrimp/m² was 73.66%, biomass 1,981.87 kg, FCR 1.59 and productivity 12.38 tons/ha. This shows that biomass, SR, and productivity decreased while FCR tended to increase in cultivation with a stocking density of 190 shrimp/m². The results of water quality showed an increase in the Total Organic Matter value of 110-250 mg/l at a stocking of 190 shrimp/m². This shows that there is an increase in organic matter in the maintenance pond which affects the survival of shrimp in the pond so that it affects the biomass and productivity of whiteleg shrimp. A stocking density of 140 shrimp/m² can be recommended for application in intensive whiteleg shrimp cultivation.

Thu, 27 Feb 2025 00:00:00 +0800

Eel seeds for aquaculture are primarily sourced from the wild. These seeds respond poorly to feed during the initial rearing phase. Therefore, this study aimed to provide feed that eels can consume in the early stages of culture. This study used an experimental method by testing the level of eel acceptance for natural feed, namely worms (Lumbricus sp.), golden snails (Pomacea sp.), chicken intestines, and maggots (black soldier flies), which will then be used as attractants mixed with pellet flour. Based on the order of feed selection and the time duration of eel response to the feed, eels preferred earthworms and snails as feed compared to maggots and chicken intestines. However, the four tested feed types can be consumed by eels. Mixing earthworms with pellet meal in the form of paste feed was responded well by eels. Eels consumed more (p <0.05) pellet meal mixed with earthworms than feed that did not have earthworms added to it. The incorporation of earthworms as an attractant in paste feed, as much as 50%, produced the same eel growth (P> 0.05) as eels given 100% worms. It indicated that a combination of artificial feed and earthworms could facilitate the consumption of artificial feed by eels in the initial phases of culture.

Fri, 28 Feb 2025 00:00:00 +0800

Stocking density plays a very important role in the process of Whiteleg shrimp seeding. High stocking density in Whiteleg shrimp larvae will affect the growth and survival of the shrimp. This study aims to analyze the growth and survival of whiteleg shrimp larvae with different stocking densities. The research method used is experimental. This study consists of 1 stocking density treatment with a stocking density of 115 fish/L (treatment A) and 176 fish/L treatment (D) which is repeated 3 times. This study consists of 6 tanks with a volume of 13,000 liters. During the maintenance period, the larvae were given natural feed and artificial feed. The parameters tested were water quality (temperature, pH, DO and salinity), survival and growth parameters. Data analysis used ANOVA. The results of the study showed that the population in the form of a presentation of each larval stage of treatment A was significantly different from treatment D. Likewise, the results of the survival analysis of treatment A were significantly different from treatment B. This means that treatment A with a density of 115 fish/L had better survival compared to a density of 176 fish/L. However, the results of the analysis in treatment A were not significantly different from treatment D. This means that the stocking density does not affect the growth of post larvae. The recommendation for proper stocking density in larval maintenance to produce high survival is to use a stocking density of 115 fish/L

Microplastics are plastic particles formed from plastic degradation to a size of <5 mm. Microplastics in waters can have adverse effects on marine organisms, aquatic ecosystems, and humans. This study aims to determine the shape, size, color, abundance, and distribution of microplastics and to determine the relationship between water quality and the abundance of microplastics in the waters of Pasaran Island. The study was conducted in November-December 2022 in the waters of Pasaran Island. Preparation and identification of microplastics in water samples were carried out in the following stages: sample preparation, organic material degradation, density separation, sample sorting, and observation of microplastic types. Data analysis was carried out using the principle component analysis (PCA) method using the Statistical Program for Social Science (SPSS) version 24 with physical and chemical parameters of the waters. Based on the study, 4 forms of microplastics were obtained, namely fiber, fragments, films, and pellets. The form of microplastic that dominated the four stations was the fiber form at 45.1%. The highest abundance of microplastics was at Station 2 (mangrove ecosystem) at 22.63 particles/liter. PCA analysis showed that the abundance of microplastics in the form of fibers, fragments, films, and pellets was negatively related to pH, salinity, current, temperature, and brightness. Increasing public awareness in reducing the use of single-use plastics and managing plastic waste needs to be done to reduce the abundance of microplastics in the waters of Pasaran Island.

Simultaneous analysis of the signification obtained was 0.00 < 0.05, meaning that the mesh size and net length together had a significant influence on the production of mantis shrimp catch, while partially the significance value for the mesh size was 0.00 < 0.05 and the net length also had a significance of 0.00 < 0.05 which means that the mesh size and net length had an effect on the production of mantis shrimp catch. Based on the elasticity analysis, the value of the parameter coefficient of the cobb douglas regression equation is 1.229 or greater than 1, which means that the production of mantis shrimp catch is included in the category of increasing return to scale or the change in output obtained will be greater than the input used

STUDY OF GONAD MORPHOANATOMY AND FECUNDITY OF NILEM FISH (Osteochilus vittatus) WITH SPIRULINA SUPPLEMENTED FEED

Muhammad Azharul Rijal, Ikhsan Pratama, Susanto Susanto, Rendi Marta Agung — Fri, 28 Feb 2025 00:00:00 +0800

Nilem fish (Osteochilus vittatus) is a fish native to eastern Indonesia. People in general like nilem fish due to many factors. The demand for nilem fish increases every year. This increase in demand must be accompanied by an increase in reproductive performance so that the stock of nilem fish is always maintained. Reproduction is the ability of an individual to produce offspring. There are several factors that greatly influence reproductive success, including environmental factors and food. Food content that is high in protein can improve fish reproductive performance. Spirulina platensis is a type of blue green algae that can live in fresh and brackish waters. The content of macromolecules and micromolecules in spirulina is very high. The protein contained in spirulina ranges from 55-65%, 5-7% fat, while the micromolecules contain 6-13% amino acids, 5% minerals. This research was conducted using a completely randomized design method with four treatments and four replications. The results of this research are that the addition of spirulina flour has a good effect on the morphoanatomical response of nilem fish. Giving spirulina flour had a real effect on GSI, HSI and fish weight, while fish length, fecundity and VSI had no real effect. The optimum dose in this study was P2 30g spirulina flour in 1 kg fish feed. Based on this research, feeding spirulina supplementation can increase the reproductive response of nilem fish

An alternate raw material for the production of collagen is the skin of tilapia fish, which is a fishery waste. As a naturally occurring humectant that helps to keep skin moisture, collagen is frequently found in cosmetic goods like body cream. The goal of this study is to ascertain the ideal amount of tilapia skin collagen to add in order to produce body cream with the best physico-chemical quality. This work employed an experimental approach using a complete randomized design (CRD) that included five replications and four treatments of increasing the collagen concentration of tilapia skin: 0%, 3%, 3.5%, and 4%. Cream pH, cream homogeneity, cream spreadability, and cream wetness were among the parameters measured. While the cream's pH, spreadability, and moisture were statistically parametrically assessed using analysis of variance (ANOVA), the homogeneity of the cream was analyzed descriptively and compared. The study's findings indicated that 4% was the ideal amount of tilapia skin collagen to add to the cream.

Syalyva Hamidah, Annur Ahadi Abdillah, Laksmi Sulmartiwi — Fri, 28 Feb 2025 00:00:00 +0800

Smart packaging is currently demanded to monitor the spoilage level of packaged products, for instance fishery products, characterized as perishable food. Smart packaging requires a halochromic substance, for instance, natural pigments extracted from fruits or flower. The natural pigment extracted from the plant should have a halochromic ability for example anthocyanins compound. Anthocyanin compounds are incorporated to edible film to produce smart film. The smart film has the ability to screen the quality and to monitor freshness of fishery products by demonstrating color changes from purple or blue to green and then yellow color after being exposed to spoiled conditions. The color changes are induced by changes of pH and TVB-N production in deteriorated of packaged fishery products. Moreover, smart packaging is able to provide real-time information to consumers regarding product freshness, thus enhancing the safety and maintaining the quality of food products. In addition, the advantages of a smart packaging system include simple and inexpensive production, providing "best before" information, and potentially reducing unnecessary food waste

Rahmat Sudarma, Indra Cahyadinata, Gita Mulyasari, Supriyadi Supriyadi — Fri, 28 Feb 2025 00:00:00 +0800

According to data from BPS (2023), the capture fisheries production in Bengkulu City reached 41,919 tons in 2022. Despite its significant potential, fishermen’s income levels are highly dependent on unpredictable, uneven, and difficult-to-forecast catch results, often leading to their classification as "the poorest of the poor." This study aims to examine the income and welfare of small-scale fishing households in Bengkulu City, a region with substantial capture fisheries potential. Although the city recorded a production volume of 41,919 tons in 2022, many fishermen in this area continue to face challenges related to low welfare levels. Using welfare indicators from the National Population and Family Planning Board (BKKBN), this study analyzes the income and welfare levels of fishing households and explores the relationship between them. Primary data were collected through direct interviews and questionnaires, with small-scale fishermen selected using accidental sampling. Data analysis was conducted using the Chi-square test to determine the correlation between income and welfare. The findings indicate that the average monthly income of small-scale fishing households is IDR 2,130,553. The welfare levels of these households are categorized into three groups: Sejahtera II (26%), Sejahtera III (49%), and Sejahtera III Plus (25%). The Chi-square test results show a significance value of 0.010, indicating a significant relationship between income and fishermen’s household welfare. These findings suggest that income is the primary factor influencing the welfare of small-scale fishermen. Increasing income levels can serve as a strategic approach to improving the quality of life for fishermen and their families
