Abstract

Vannamei shrimp (Litopenaeus vannamei) holds significant economic importance in Shrimponesia as a prominent shrimp commodity. The post-larval stage often encounters challenges, primarily due to the shrimp's limited ability to adapt and survive in a new environment. Stocking density is a crucial factor influencing the growth and production performance of vannamei shrimp culture. This study aims to assess the optimal stocking density for achieving optimal growth and survival in L. vannamei. A 40-day maintenance trial was conducted at UD Mina Rahayu Kalianda to investigate the impact of different stocking densities on water quality in the maintenance media. The study utilized containers with varying stocking densities: treatment A (1 shrimp/L), treatment B (1.5 shrimp/L), and treatment C (2 shrimp/L), each with three replications. The findings revealed survival rates (SR) of 83.33% for treatment A, 62.78% for treatment B, and 58.33% for treatment C. Mean Body Weight (MBW) values were recorded as 1.2592 g/shrimp for treatment A, 1.1216 g/shrimp for treatment B, and 0.7728 g/shrimp for treatment C. Average Daily Growth (ADG) results showed 0.0313 g/shrimp for treatment A, 0.0279 g/shrimp for treatment B, and 0.0192 g/shrimp for treatment C. Based on the study, the recommended stocking density for white vannamei shrimp is 40 shrimp/L, demonstrating improved growth and survival rates for this species.

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

Anchovy is one of potential commodities widely found and caught by fishermen in FMA-572 West Sumatra. Examining its exploitation rate is a part of taking control and monitor toward the fishing activities to avoid overfishing possibility. This recent study aims to calculate exploitation rate and oceanographic characteristics of anchovy fishing grounds. The data was collected from Bungus Oceanic Fishing Port, West Sumatra in 2018-2022. Meanwhile, sea surface temperature and chlorophyll data were obtained from https://marine.copernicus.eu/ and https://oceancolor.gsfc.nasa.gov 2018-2022, respectively. The results showed that the exploitation rate of anchovies in 2020 and 2022 has exceeded maximum sustainable yield categorized as overexploitation with a percentage of 130.44% and 112.84%. Anchovy catches are significantly influenced by oceanographic factors with F value 0.00000115 ( 0.05). An increase in CPUE value is align with chlorophyll increase and in contrary to sea surface temperature. The findings are expected to give an overview related to anchovy fishing activities implementation and become an input for fisheries governance that lead to sustainable fisheries management.Keywords:FMA-572MSYOverfishingSustainable fisheriesStolephorus sp

Abstract

In addition to having high economic value, catfish (Clarias sp.) can also be cultivated quickly and they can adapt well. The demand of catfish is in line with the increase in production which is expected to remain efficient and environmentally sound. Biofloc technology has also been implemented in catfish for increasing productivity. Biofloc utilizes the activity of heterotrophic microorganisms and autotrophs for the conversion of organic waste into floc and is used as fish feed. This study aims to examine the effect of the use of molasses with different doses (C/N ratio) on the growth and survival rate of catfish. This study was conducted with as many as 3 treatments with 3 repetitions each except for the control. The treatment with the ratio of molasses in each of them: A: C/N of 10:1; B: C/N of 15:1; C: C/N of 20:1, and D without molasses given as control. The study using 240 catfish measuring 10-12 cm was carried out for 30 days with sampling every 10 days. It aims to determine the average growth, daily growth, and survival rate of test biota during the study. Based on the results of this study, it can be concluded that the use of different doses of molasses in catfish farming, and biofloc technology will affect the growth and survival rate of farmed catfish. Catfish farmed with biofloc technology at a C/N ratio of 15:1 show the best results on their growth and survival rate. In addition, catfish farming with a biofloc C/N ratio of 15:1 has a better economic analysis when compared to conventional catfish farming. In summary, the use of biofloc based on research results can be a recommendation to be applied in the community, especially among catfish farmers.

Abstract

Gastropod communities are one of the important components of the food chain in seagrass meadows. This study aims to investigate the diversity of gastropods in the distribution of the seagrass beds at Oransbari Bay. This study was carried out in November 2022, using the line transect method. Data collection is carried out at three stations, where each station is divided into three transects. A total of 36 species consisting of 16 families and 5 orders, were recorded in this study. The total density of gastropods found in the waters of Oransbari Bay ranged from 5.77-9.43 ind/m2, with an average of 6.99 2.10 ind/m2. Conus sp. has the highest density value of any gastropod. Meanwhile, for seagrasses, five species from four clans and two families were obtained. The percent cover of seagrass ranges from 17.05 3.30% 58.90 22.90% with an average of 40.18 21.3%.Halophila minor and Thallasia hempricii showed a positive correlation with gastropod density. The value of the gastropod diversity index is in the medium category, the gastropod evenness index is in the stable category, and the gastropod dominance index is in the low category. The results of this study provide a base for a proper gastropod checklist at Oransbari Bay. Future research is recommended that involves a more detailed studies on the feeding ecology and habitat preference of the gastropods.Keywords:DiversityDistributionGastropodsSeagrass bedsOransbari bay

Abstract

It is important to maintain a healthy marine ecosystem to support eco-friendly and sustainable fishery development. Implementation of Ocean Health Index (OHI) started globally in 2012, and it has been strongly recommended to be conducted at all levels: locally, nationally, and regionally. Indonesia has modified OHI for its national assessment, which its called Indeks Kesehatan Laut Indonesia (IKLI). IKLI has been estimated since 2020 and introduction applied at the sub-national level. This study is an attempt to implement IKLI in Maluku province with the main objective is to estimate score of a partial IKLI, based on clean waters (goal no. 9) and biodiversity (goal no. 10). Samples were taken from Ambon and Baguala Bays between June and September 2022. For clean water goals, the parameters used were concentration of phosphate, nitrate, silicate, dissolved oxygen (DO), pH, and the number of ports that implemented green principles. The parameters of water quality of silicate, DO and pH in those two bays are within the range of government-mandated standards, except for nitrate and phosphate concentrations which are not. For the biodiversity goal, the parameters used are the species composition of mangrove, seagrass, fish, and coral. The IKLI biodiversity score was low due to the high level of human activity pressure at the two selected study sites. This study demonstrates the applicability of the IKLI in a partial analysis, and its usefulness in highlighting existing data and knowledge gaps. The study suggests that a comprehensive IKLI assessment should be conducted in Maluku Province. Meanwhile to improve the national-level IKLI assessment, actions should prioritize improving water quality management, expanding marine protected areas, and monitoring coastal ecosystems, especially those heavily affected by human activities.KeywordsArchipelagonutrientOHIIKLI Maluku

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

The tuna fishing industry significantly contributes to greenhouse gas (GHG) emissions primarily through fuel oil usage. This study investigates the environmental impact of tuna transportation, focusing on emissions from fishing vessels and vehicles. Carbon footprint calculations for fishing vessels utilize the IPCC, 2006 formula as referenced in KLH, 2012. Smaller purse seiners (10-20 GT) emit 2.88 kg CO2per trip per kilogram of tuna, while those (20-30 GT) in PPS Kutaraja emit 3.58 kg CO2. Larger purse seiners exhibit higher emission rates: 7.3 kg CO2 (20-30 GT), 9.9 kg CO2 (30-40 GT), 8.6 kg CO2 (40-50 GT), and 8.4 kg CO2 (50-60 GT) per trip per kilogram of tuna. Vehicle emissions for tuna transport vary, with the Honda Blade FI 125 emitting 0.00625 kg CO2, Supra X 125 emitting 0.00450 kg CO2, Viar Tiga Roda emitting 0.00458 kg CO2, Revo Fit emitting 0.0007 kg CO2, Jupiter emitting 0.00063 kg CO2, and Vega ZR Yamaha emitting 0.0006 kg CO2 per kilogram of tuna.Keywords:Carbon FootprintEmissionFsihing VesselsGreen TransportationsSupply ChainFishing Activties
