Abstract

Information on the catch composition and catchable size of lobsters in Lebak waters remains limited, posing challenges for effective fisheries management. This study aims to assess the technical performance of the lobster fishery and analyse catch composition. Data on technical performance were collected through interviews with fishers and lobster collectors using random sampling, while a census approach was applied to measure carapace length and weight for 589 lobsters. A descriptive quantitative analysis was conducted to evaluate the length-weight relationship of lobsters. The findings indicate that fishers predominantly use polyamide monofilament gillnets with a mesh size of 3.5–4.0 inches, operating traditional outrigger boats of 2–3 GT and 7 GT for single-day fishing trips in Lebak waters. Panulirus homarus was the dominant species in the catch. The sex ratio of lobsters was imbalanced, and their growth pattern exhibited negative allometry (b < 3). An assessment of catch sizes against the standards set by PERMEN-KP No. 16/2022 revealed a high proportion of undersized lobsters in the Binuangeun Estuary, including P. penicillatus (78–83%), P. homarus (80–100%), P. ornatus (23%), P. longipes (90–100%), and P. versicolor (65–100%). Similarly, in the Cibareno Estuary, the percentages of undersized lobsters were P. penicillatus (84–100%), P. homarus (98%), P. ornatus (0%), P. longipes (100%), and P. versicolor (92%). These findings highlight the need for stricter management measures to ensure sustainable lobster fisheries in the region. Keywords: catchable, Lebak Banten waters, length weight, lobster, sex ratio

Abstract

The high level of fishing activity with small fishing vessels has resulted in relatively high utilization of marine space in coastal areas, manifesting changes in fishing grounds. Thus, this research aimed to analyze water quality, fishing intensity and to determine the level of degradation of fishing grounds in the northern waters of Banten Province. This research was conducted from June to August 2023 in the northern waters of Banten Province. Data collection was carried out using survey, remote sensing, and interview methods. Water quality data consisting of sea surface temperature, brightness, salinity, light attenuation coefficient, total suspended solids, and chlorophyll-a were analyzed descriptively. Eco-friendly capture fisheries data were taken directly from 120 fishermen and analyzed based on the CCRF criteria. Degradation status was determined by combining weight of water quality conditions and eco-friendly capture fisheries. Based on the research results, the northern waters of Banten Province is in good condition for biota life. Fishing equipment is dominated by eco-friendly fishing gear. Nevertheless, several parts of northern waters in Banten Province have experienced light degradation of fishing areas (18.28%) and the heavy degradation (7.71%). The use of marine space for capture fisheries in the northern waters of Banten Province is relatively high, around 50 units of fishing gear for 1 hectare of water.Keywords:EnvironmentFishing intensityFishing gearSpatial mappingWater quality

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. Key words: biomass models, fish stocks, precision fishing, sustainable potency, TAC

Abstract

The use of hydroacoustic surveys simultaneously with trawl swept area is expected to complement and increase the accuracy each other in estimation of the fish stock resources, especially demersal fish. Therefore, advantages and disadvantages of each method will be disclosed. The purpose of this study was to compare the density of demersal fish from detection of hydroacoustic surveys toward catches of bottom trawl, and to determine the factors that influence differences in fish density estimated of swept area and acoustic method. The study was conducted on May, August and November 2012 around Tarakan waters, North Borneo, using echo sounder Simrad EY60-120 kHz and bottom trawl simultaneously to measure density of demersal fish. Demersal fish density estimation of the two methods showed a highly significant difference. Difference in the estimation of fish density was affected by catchability, dead zone area of trawling, and fish behavior.

Abstract

The Saleh Bay is one of the bays in West Nusa Tenggara utilized as the grouper fishing ground. However, in the previous spawning potential ratio study, some grouper species have been overexploited in Saleh Bay. This study aimed to estimate the status of grouper utilization with a catch per unit effort (CPUE) approach and the spatio-temporal fishing intensity of grouper in fishing grounds in Saleh Bay. Data were gathered using the fish landing data and geo-reference of fishing ground grouper in Saleh Bay. This study used several methods: descriptive analysis, catch per unit effort, and spatial-temporal analysis. The result showed that the catch unit effort positively impacts production, with the increasing trend of grouper fishing in Saleh Bay waters. The CPUE value in 2016 was 2.82 kg/trip, while in 2020, it increased to 3.99 kg/trip. Spatially and temporally, fishers caught grouper around small islands such as Liang Island, Dempu Island, Lipan Island, Takat Nusa Pudu, and Rakit Island. The highest intensity of grouper fishing around the marine protected area, namely Rakit Island, Liang Island, and Ngali Island. Keywords: catch per unit effort, fishing ground, grouper, Saleh Bay

Abstract

The ratified countries of PSMA 2009 are mandated to determine their implementing port without specifying any particular standards. The presence of port standards will ensure the effectiveness of services in preventing and eradicating IUU Fishing. Therefore, standards are needed to optimize the main objectives of the 2009 PSMA, especially in Indonesia, an archipelagic country with diverse fishing port classes and different management systems between general cargo ports and fishing ports. The objectives of this research are (1) to develop service standards for ports implementing PSMA 2009 and (2) to examine the readiness of ports implementing PSMA 2009 to prevent IUU fishing. This research uses content analysis and literature review methods. The results of this study reveal that Indonesia has legally adopted the 2009 PSMA, but there are two port state regimes that prevent and reduce IUU fishing such as Port State Measures and Port State Control. The service standards that must be met by ports designated to implement PSMA 2009 are (1) application services, including service officers receiving application letters and risk analysis officers, and (2) inspection services, including trained officers, authorized officers, English-speaking officers, inter-agency coordination mechanisms, and officer identity. While Benoa General Cargo/Public Port is ready to implement PSMA 2009, its fishing port still needs improvement.

Abstract

Squid jigging fisheries in Indonesia have developed rapidly, leading to a substantial increase in energy consumption due to the growing number of squid jigging units. Traditionally, metal halide (MH) lamps with electrical power ranging from 24 to 30 kW are used as light attractors. This study aimed to design a LED (light-emitting diode) lamp for squid fishing with a light distribution pattern comparable to that of MH lamps and to evaluate its fuel consumption. The research involved the design and construction of an LED-based squid lamp, measurement of light intensity in air, and comparison of fuel consumption between LED and MH lamps under laboratory conditions. Underwater light intensity was measured in the waters of Banten Bay. The electronic system employed components with total LED power of 450 watts. Results showed that the average light intensity of the LED lamp decreased by only 10.57% compared to the MH lamp. The Specific Fuel Consumption (SFC) of MH lamps ranged from 0.00162–0.00176 kg/hp·h, while that of LED lamps ranged from 0.00109–0.00119 kg/hp·h. The LED system achieved a fuel efficiency of 40.54%, indicating a 19.03% improvement compared MH lamps. Further field-scale experiments are required to validate effectiveness in actual squid fishing operations. Key words: intensity, light, measurement, squid
