Abstract

Catfish have high economic value, fast growth, and are easy to cultivate. This is the reason why catfish cultivation is increasing. However, there are still obstacles in the cultivation process, namely the threat of disease, one of which is the Motile Aeromonas Septicaemia (MAS) disease caused by Aeromonas hydrophila bacteria. The countermeasure can be done by using active compounds found in plants, including banana stems. This study aimed to determine the effectiveness of giving banana stem extract to carp culture media and treating A. hydrophila disease. This research used an experiment with a completely randomized design. The treatments tested were the addition of banana stem extract at a dose of 5% (treatment A), 10% (treatment B), 15% (treatment C), and antibiotics (treatment K-), and without extract treatment (treatment K+). Each treatment was repeated three times. The results showed that the administration of banana stem extract significantly affected the fish's erythrocytes, leukocytes, and blood glucose. Leukocyte differential observation showed that kepok banana stem extract had a significant effect on eosinophils, lymphocytes, and neutrophils but no significant effect on monocytes. In analyzing fish blood, the optimal values were 7.640.190a cells/mm3 for leukocytes, 3.600.116d cells/mm3 for erythrocytes, 656.028b mg/dl for glucose, 74.670.577d% for lymphocytes, 5.670.577a% for neutrophils, and 00a% for eosinophils. The results indicate that treatment B with 10% kepok banana stem extract was the most effective in administering the extract to catfish infected with A. hydrophila bacteria.Keywords:Dumbo catfishLeukocytesErythrocytesGlucoseMusa AcuminataAeromonas hydrophila

Abstract

One of the regions contributing to stingray fisheries production in Indonesia is Aceh province. The condition of stingray fisheries in Indonesia is currently facing challenges as the population is decreasing while the demand for stingray fishery resources domestically and abroad continues to increase. This condition certainly requires integrated stingray fisheries management efforts so that the rays population, especially in the waters of Aceh province, remains sustainable. This study aimed to determine the number, type, and distribution of stingray fishing grounds landed at the Ujong Baroh Fish Landing Base (PPI). The research was carried out in 2 stages; the first stage was to conduct a field survey by following fishermen directly to the sea and using interview questionnaires, and the second stage was to take satellite image data of sea depth, fishing location, and fishing distance and then make a map of stingray fishing ground distribution landed at Ujong Baroh Fish Landing Base, West Aceh. The number of stingray catches landed at Ujong Baroh Fish Landing Base during the study was 428, consisting of 11 species: 369 Maculabatis macrura, 42 Myliobatis tobijei, 14 Rhynchobatus australiae, 28 Dasyatis kuhlii, 8 Pateobatis uarnacoides, 7 Gymnura zonura, 6 Himantura leoparda, 2 Rhina ancylostoma, 2 Rhinobatos borneensis, 1 Aetobatus narinari, and 1 Taeniuriops meyeni. The results of the mapping analysis showed 18 distribution points of stingray fishing grounds and 4 fishing locations that obtained stingray catches, namely at the coordinates of 338.136'N and 9629.056'E, 42.144'N and 962.431'E, 416.599'N and 9532.000'E, 334.51472'N and 9625.80414'E.Keywords:MappingFishing GroundStingrayEastern Season

Abstract

Plastic debris is one of the serious problems in urban cities, including Banda Aceh city and Aceh Besar district, Indonesia. This waste is degraded into a small particle called microplastics. This waste has the potential to pollute the waters in the coastal area. The objective of the present study was to analyse the microplastic contamination of the sea surface waters of Banda Aceh City and Aceh Besar District. Sea surface water was sampled from three locations, namely Gampong Jawa (Station 1), Alue Naga (Station 2), and Krueng Raya (Station 3) during January to March 2024. The results showed that there were four forms of microplastics found in the sea surface water sample, namely fragments, fibers, films, and pellets with nine colours, namely black, brown, blue, clear, red, yellow, green, pink, and purple. The fragments and black are the dominant form and colour of microplastic in the sea surface water of Banda Aceh city. The highest number of microplastic particles was found in Alue Naga waters (21.04 particles/L) and the least in Gampong Jawa waters (16.6 particles/L). Therefore, it is concluded that the surface of the seawater studied in this study has been contaminated with microplastics.Keywords: Microplastics Sea surface water Plastic waste Banda Aceh City Aceh Besar District

Abstract

Euglena sp. contains several metabolites that play a role in various sectors, likely biofuels, food, feed, and pharmaceuticals. Multiple treatments are required to increase the content of Euglena sp. to support its use. In this study, a chemical stimulant in the form of lignosulfonate was added to Euglena sp. in order to increase its natural potency as measured by lipid, carbohydrate, protein, paramylon content, and biomass productivity. lignosulfonate is a macromolecular polyelectrolyte and anionic surfactant which is unique and multifunctional. This lignosulfonate can act as an emulsifier, dispersing agent, binder, and stabilizer of lipids in Euglena sp. cells. This can help improve the physical quality of pellets in Euglena sp. cells. In addition to the lignosulfonate chemical stimulator, it can affect the growth process of Euglena sp. so that it can produce good-quality cells. In addition, it also aims to determine the accumulation of significantly different metabolites. The method used was a Completely Randomized Factorial Design (CRD) with three treatments and three replications. The results obtained indicated that the addition of lignosulfonate was significantly different in the cell and protein density tests. Therefore, the optimal concentration of lignosulfonate can be used as an agent to increase the growth rate and metabolites of Euglena sp. significantly

Abstract

Many Asian countries, including Indonesia, have experienced negative effects from pollution brought on by industrialization and modernization, which have harmed freshwater ecosystems as well as natural habitats. Red macroalgaeand other creatures that depend on these ecosystems for their survival may suffer as a result, which could increase the strain on freshwater ecosystems and resources. Due to freshwater red macroalgaeare primary producers in their own ecosystems, they are essential to the cycling of nutrients and the preservation of water quality. The objective of this study is to evaluate freshwater red macroalgae in Indonesia utilizing various approaches particularly emphasis on DNA barcoding. As a result, molecular methods like DNA barcoding are employed to uncover hidden species and elucidate the evolutionary connections between different taxa, thereby exposing the diversity of red macroalgae. It is anticipated that the outcomes will yield data for further research.Keywords:DNA barcodeFreshwaterHidden speciesMolecularRed macroalgae

Abstract

Studying the biological reproduction of fish is important for determining the spawning season and providing several management options to protect the fisheries. The study conducted length and biology reproduction sampling of Mackerel scad (Decapterus macarellus) caught by mini purse seine landed in Tobelo coastal fishing port during 20152016. The total sample consisted of 1228 individuals, 526 males and 671 females with size distributions ranging from 12.50 to 29.90 cmFL. Results showed that there were 432 immature and 94 mature male fish and 582 immature and 89 mature female fish. The growth pattern for male fish is negative allometric (b3) while for females is isometric (b=3). The highest GSI value for male was recorded during May and November, while for females it was in May and October. Based on this result, the spawning season of mackerel scad in the North Halmahera waters is predicted to occur in March-May and August-October, by the first and second transition seasons. The study found that the length at first maturity (Lm) was 24.90 cmFL for male fish and 26.41 cmFL for female fish, the Lm bigger than Length at first capture (Lc) of 21.93 cmFL. This means the fish was caught before mature gonads and had a chance to spawn.Keywords:Mackerel scadSmall pelagic fishHalmahera watersGonadosomatic indexSpawning season
