Abstract

The untapped potential of fish processing production waste as a source of fish feed ingredients makes it a promising resource due to its widespread availability. This study aims to evaluate the process of producing fish waste silage through probiotic fermentation to assess the resulting quality post-fermentation. Employing an exploratory descriptive method, this research draws from diverse literature sources, encompassing books, national journals, and international publications. The comparison of findings from prior research indicates that fermenting fish waste with microbes, particularly lactic acid bacteria, enhances its protein content, positively impacting fish growth performance. Introducing silage at a 10% dose achieves a tilapia survival rate of 83.33%, while a 25% silage addition yields a relative growth rate of 222.63% for catfish and a feed conversion ratio of 1.06 for tilapia.Keywords:FermentationFish wasteFish silageLactic acid bacteria

Abstract

Aceh is a province located in the western part of Indonesia, and most of its region is a coastal area that faces rapid population growth, which puts pressure on sectors like fisheries and marine resources. One of those is the West Aceh District the location of this research. Capture fisheries represent a crucial economic sector for the livelihoods of many communities, provided it is well-managed. One of the important factors contributing to the decline in fish populations is the use of environmentally harmful fishing gear. This paper aims to determine a strategy for environmentally- friendly capture fisheries management based on the code of conduct for responsible fisheries in West Aceh District, which is crucial for protecting aquatic habitat sustainability and future fish stock populations. A descriptive method combined with a survey was conducted during the research and SWOT was used as a data analysis method. The result is several important measures should be implemented in Aceh Barat District based on the code of conduct for responsible fisheries, from providing enough information and training for fishermen to enhance their knowledge and skills on sustainable fisheries management, to constructing representative fishing ports is also necessary to support efficient and environmentally friendly fishing activities, lastly, maximising the monitoring of fishing gear usage that meets the environmental standards and strengthening the law enforcement.Keywords:Strategic approachesSustainable fisheriesCCRFWest AcehMeulaboh

Abstract

Simeulue Regency has the potential for diverse and abundant marine resources; one of which is octopus (Octopus sp.). However, the problem faced by Simeulue fishermen in carrying out octopus fishing activities is that they only rely on natural phenomena or natural signs studied from generation to generation (traditional) to catch octopus. Therefore, the catch obtained is uncertain and takes a long time. The purpose of this study was to determine the number and weight of octopus catches landed in three sub-districts namely Teupah Barat, Teupah Selatan and Alafan, and then make a map of distribution of potential octopus fishing groud in the three sub-districts. The research method used in this study was a survey method by observing octopus catching units. The results showed that the total number and total weight of octopus catches in three sub-districts from the highest to the lowest were Teupah Barat, amounting to 176 heads and weighing 90,47 kg; Teupah Selatan amounting to 115 heads and weighing to 69,54 kg; and Alafan amounting to 114 heads and weighing to 46,97 kg, where the octopuses caught were all adult categories and fit to be caught. As for the potential areas for octopus fishing in the three sub-districts were as follows: Teupah Barat with 3 potential areas (points E, F and A); Teupah Selatan with 2 potential areas (points E and F); Alafan with only 1 potential point (point K).Keywords:MappingFishing groundOctopusSimeulue

Abstract

Seagrass restoration practice of transplanting grown seagrass from a donor to the planting site is discovered to disrupt the existing ecosystems. An alternative method includesthe use of seedlings, which requires a protected germination environment to survive. At the initial stage, the seedlings need adequate space for growth and expansion of root systems. However, cultivating seagrass seedlings in aquariums is challenging due to limited space. Therefore, this study aimed to investigate the growth and development of aquarium-cultured seagrass seedlings and evaluate the impact of different spacing on growth. Seedlings were cultivated in the laboratory under 2 treatments, each lasting 3 months. Enhalus acoroides seedlings collected from Dompak Island, Tanjungpinang, were used with varying planting distances for each treatment. The results showed that Treatment A (4 cm spacing) had a lower survival rate (66.73%) compared to TreatmentB (1.5 cm spacing) (97.78%) due to a fungus outbreak.However, Treatment B had slower growth than A, suggesting potential problems with water quality and increased competition for resources in denser plantings. In this study, the significance of planting spacing was outlined and a statistically significant difference was discovered in seagrass growth between various treatments (P0.05). A rapid growth rate of 2.08-3.02 mm/day was observed in leafs, which exceeded the value observed in previous investigations conducted under similar conditions and species. It was important to acknowledge that leaf length was also 17.5-21.6 cm, exceeding the values observed in another experiment using lab-cultured E. acoroides. Root lengths were comparatively shorter (7.6-8.2 cm), which signified the dynamic nature of seagrass development. In conclusion, addressing environmental conditions and optimizing planting spacing, was essential for sustainable growth.Keywords:EnhalusGrowthSeagrassSeedlingsSpacing

Abstract

This study investigates the potential of natural stimulants, specifically ecdysteroids, in accelerating the molting process in mangrove crabs. The research was conducted by analyzing various plants containing ecdysterone and their effects on the crabs. The results indicate that forest fern leaves and mulberry leaves are effective sources of ecdysterone in stimulating molting and growth in crabs. The use of such natural stimulants has the potential to enhance productivity and reduce reliance on synthetic hormones in crab cultivation. However, further research is needed to determine the optimal dosage and to understand the mechanisms of ecdysterone action in crabs in more detail. The main challenge in implementation is adjusting the dosage and frequency of natural stimulant administration to achieve optimal results without disrupting the balance of the cultivation ecosystem. This approach offers an environmentally friendly alternative for the sustainable development of crab farming.

Abstract

The many herbal plants in Indonesia that contain antimicrobial substances such as Calotropis gigantea, Moringa oleifera and Cassia alata L. leaves are attractive and have the potential to be used to prevent and treat bacterial diseases in fish. This study aims to determine the effectiveness of administering a combination of multi-herbal ingredients, namely M. oleivera, C. gigantea and C. alata L. leaves in the treatment of O. niloticus tilapia infected with the pathogenic bacteria S. agalactiae. The experimental design used a completely randomized design with 6 treatment levels and 3 replications, namely treatment A (Fish that were not infected with S. agalactiae), B (Fish infected with S. agalactiae), C (Fish infected with S. agalactiae + soaked in thistle leaf extract 800 ppm+ Moringa leaf extract 1000 ppm)), D (Fish infected with S. agalactiae + soaked in C. gigantea leaf extract 800 ppm + C. allata leaf extract 10 ppm), E (Fish infected with S. agalactiae +soaked in Moringa leaf extract 1000 ppm + C. allata leaf extract 10 ppm) and F (Moringa leaf extract 1000 ppm+C. gigantea leaf extract 800 ppm + C. allata leaf extract 10 ppm). The results showed that the combination of M. oleivera, C. gigantea and C. alata L. extracts had a significant effect (P0.05) on the survival rate ofO. niloticus. Treatment (E), combination of M. oleivera leaf extract 1000 ppm + C. alata L leaf extract 10 ppm, showed the fastest healing of the body and the highest survival rate of tilapia, namely 80%.Keywords:Multi herbal leavesPatoghenImunnity

Abstract

Plastic waste that is not managed properly will damage the environment by polluting the ecosystem. Plastic in waters can turn into micro-sized plastic waste. Plastics whose size is less than 5 mm are called microplastics. The emergence of microplastic pollutants is caused by increasing population activity in Percut Waters. Percut waters are waters located in the coastal area of North Sumatra where there are many anthropogenic activities that cause the emergence of microplastics. Microplastics can have a negative impact on exposed marine biota. Nowadays microplastics are not only found in the environment, but can also accumulate in the bodies of organisms, for example. This research aims to determine the abundance of microplastics in fish found in Percut waters. The research was carried out in October November 2022 in Percut Waters. Fish samples were caught using nets and the samples were separated from their digestive tract and diluted with the addition of NaCl and H2O2 lauric. The average abundance of microplastics in fish samples ranged from 24294 particles. The fish species where the most microplastics were found was mullet fish with 294 particles. The most common types of microplastics found in total are fiber microplastics.Keywords:MicroplasticDigestionCoastalPercut

Abstract

Aquatic plants are adaptive living on the gradient of acidity of peat waters in Palangka Raya city, with their potential role in remediating city wastewater. This research is aimed to study the ability of several aquatic plant species to remediate organic wastewater on a laboratory scale. The treatment was done from July to September 2020 in the field laboratory, greenhouse in Palangka Raya, Central Kalimantan. We compared the phytoremediation abilities of aquatic plant species, i.e. water hyacinth (Eichornia crassipes), pickerelweed (Monochoria vaginalis (Burm. F) Presi), water spinach (Ipomoea aquatica), water primrose (Ludwigia ascedences), water lettuce (Pistia stratiotes), giant Salvinia (Salvinia molesta), and hornwort (Ceratophyllum demersum) on the wastewater of African catfish (Clarias gariepinus) by measuring coverage as an indicator of their growth and absorption ability. Physicochemical parameters measured were water level, sunlight intensity, water temperature, electrical conductivity, potential oxidation-reduction, pH, dissolved oxygen, phosphate, nitrate, and ammonia. Results showed that of seven species tested for their phytoremediation abilities on wastewater, giant Salvinia was among the highest reducing total organic matter by about 95%. The highest coverage was water lettuce by 92%, followed by giant Salvinia (79%) and water hyacinth (78%). However, phosphate and ammonia had a negative value of the relative absorption for all aquatic plant species, suggesting a surplus in concentration during incubation. In this case, absorption for phosphate and ammonia is detected from a median of the lowest concentration on each species (n = 4). Water hyacinth and giant Salvinia were the highest absorbing for respectively phosphate and ammonia. Nitrate was absorbed by 100% of all species, except hornwort of 88%. The best absorption of nitrate was by water lettuce. So, it can be concluded that giant Salvinia is the best at absorbing organic waste, followed by water hyacinth; and the best growing by coverage is water lettuce.Keywords:PhytoremediationAquatic plantAfrican catfishWastewaterPeat water

Abstract

Even though the government has established regulations regarding wages, the reality is that the wages received by crew members of fishing vessels are still not in accordance with regulations. Therefore, the purpose of this study is to identify the distribution of wages on purse seine vessels and to find out the gap between the wages received by crew. To achieve this goal, this study uses catch data for three fishing trips from March to May 2022, as well as crew wages from selling catches on the purse seine vessel PT Hasil Laut Sejati. The secondary data used is the productivity of the annual catch of purse seine vessels as well as supporting data from references related to the topics discussed. The data obtained were then analyzed using descriptive analysis, income analysis, and gap analysis. The average wage received by purse seine vessels crew is around Rp. 677,649.67 Rp. 1,190,134.00, the wages received are far below the City Minimum Wage, with a gap of 71.57% - 83.81%. The wages of Batam City purse seine crew are not in accordance with the City Minimum Wage of Batam City. Economic conditions and wages for crew members significantly require crew to continue working, to make ends meet.Keywords:CatchCrewIncome
