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

Abstract

The Government of Indonesia is implementing a Measured Fishing policy to ensure the sustainable utilization of fishery resources. However, 88% of fish stocks are currently in fully fished (35%) or overfished (53%) condition, which hinders the attainment of maximum sustainable yield (MSY). This study aims to examine the influence of initial biomass (B₀) and annual harvest rate (Yₜ) on the sustainability of annual catch (Cₜ) and remaining biomass (Bₜ) using a logistic differential equation (LDE) model. Simulations were conducted across nine fishery models, combining three levels of B₀ and three levels of Yₜ, under assumptions of carrying capacity (K) of 1000 tons and a hipothetical fish biomass with intrinsic growth rate (r) of 0.05. Results indicate that the ratio of Yₜ to the current sustainable yield (SYₜ) is the primary determinant of stock sustainability and fishery longevity, regardless of B₀. This finding suggests that total allowable catch (TAC) should not be based solely on MSY, but rather adjusted according to SYₜ, while also incorporating precautionary principles and stock recovery strategies. This approach offers a more adaptive and realistic policy framework aligned with current stock conditions and supports the long-term sustainability of capture fisheries.

Abstract

Narrow-barred Spanish mackerel (Scomberomorus commerson) is one of the high-value commercial fish species exported from the Riau Archipelago. To meet export standards, this species must fulfill specific quality criteria to be considered suitable for export. This study aims to analyze the fishing season pattern and size structure of catchable Spanish mackerel (Scomberomorus commerson) in the waters of the Riau Archipelago. Data were collected through field surveys, direct observation of catches, and analysis of gillnet vessel logbook records from 2018 to 2022. Fishing productivity was calculated using catch per unit effort (CPUE), and the seasonal pattern was identified using the Simple Moving Average (SMA) method and monthly fishing season index (Mt,b). The results showed that the fishing season for Spanish mackerel occurs from January to May, with the peak season in February. The size structure analysis revealed that 87.6% of the sampled fish were larger than 61 cm, indicating that they had reached first maturity (catchable size). Nevertheless, a portion of smaller fish was still caught, highlighting the need for improved management of fishing gear and fishing grounds to support resource sustainability. These findings, once implemented, are expected to significantly improve the sustainability of Spanish mackerel populations, offering hope for the future of this species. These findings are expected to contribute to the implementation of precision fisheries management in Fisheries Management Area (FMA) 711. Key words: catchable size, catch per uni effort, fishing season pattern, precision fisheries, Spanish mackerel

Abstract

Sharks is the dominant bycatch of purse seine and bottom longline vessels that landed in Kutaraja ocean fishing port, particularly pelagic thresher shark species (Alopias pelagicus). The management of shark fisheries in Aceh water is not well implemented. According to the IUCN red list, the pelagic thresher shark has been classified as an endangered species. The capture and trade of pelagic thresher sharks are regulated by CITES (Appendix II). So that Indonesia has to comply with the procedures of CITES due to it has been adopted through the Decree of Minister of Marine Affairs and Fisheries of the Republic of Indonesia Number 61/PERMEN-KP/2018. However, the exploitation and trading of the A. pelagicus continues and is not properly managed. It will threaten the extinction of the pelagic thresher shark population and in terms of a negative image of fisheries management in Indonesia, in particular. Thus, integrated management such as the ecosystem approach to fisheries management (EAFM) is needed to solve this problem. This study aims to evaluate the fisheries management status of the pelagic thresher shark based on EAFM indicator of fish resources domain, focusing in the Kutaraja ocean fishing port. This research was conducted by field measurement and interviews with key stakeholders. Data were analyzed using a multi-criteria analysis (MCA) approach through development of a composite index. The results showed that the trend of CPUE tends to fluctuate in the last 5 years. The total length of the sharks was relatively constant. The proportion of juvenile pelagic thresher sharks was 16% male, and 28% (female), and the shark was bycatch (1%) of the purse seine fishery, the fishing ground was getting further away and seemed to go close to the shark habitat. Based on this assessment, one could conclude that shark's fishery resources were in 'good' category, however, some indicators need to improve through better fisheries management actions.Keywords: EAFM; Alopias pelagicus; pelagic thresher shark; Kutaraja ocean fishing port

Abstract

The active operation of a trammel net by a sweeping technique is commonly used by fishermen in Cilacap, which are often referred as ciker nets. They are operated by lowering the net in a straight line and pulling the tail end from a ship moving in a full circle, while the other end functions as a circular axis. The effect of active operation allows for changes in performance with time, such as easy lifting or less buoyancy, and the unstable display of gears. This makes it necessary to perform design engineering, especially on buoys, sinkers, and high nets. However, the suitable quantity of these components for ciker net has never been ascertained. Calculations about how many buoys, sinkers, and net height to add need to be done to enhance ciker net construction for active operation. This research aimed to determine the optimum configuration of buoys, sinkers, and net height, and determine the engineering design of ciker nets based on the optimum ratio of buoyancy force to the sinking force of the trammel net. Therefore, the parameters measured include hanging ratio, stretched net length, buoyancy force, and sinking force. The results showed that the optimum configuration of buoys, sinkers, and net height was 59 pieces, 341 pieces, and 1.5 m respectively. Changes in the design of ciker nets, especially in the three components that affect the addition of buoyancy and sinking force ratio were based on the comparison of the trammel nets which was 1:5 greater than the design owned by fishermen at 1:4.Keywords:Bouyancy forceSinking forceCiker netTrammel netShrimp
