TWP Gita Nada is one of the water conservation areas in NTB Province whose reef fish resources are used by fishers around the area, especially in zones that are permitted for fishing activities. However, there are indications that the use of the area by fishers causes a decrease in the abundance and biomass of reef fish in TWP Gita Nada. Therefore, it is necessary to research the condition of reef fish stocks in TWP Gita Nada to know for certain about the availability of reef fish resources in the area. This study collected data at 11 fish landing sites around TWP Gita Nada from March 2017 to December 2021. Data were collected using a sampling technique on 35% of the total fish landing activity in TWP Gita Nada. Data consisted of fishing units, fishing operations, fishing areas, catches, fish species, and fish length. Data analysis in this study used a length-based stock assessment approach to identify the condition of reef fish stocks and their utilization status. The results indicated that 271 species of reef fish landed in the TWP Gita Nada waters conservation area were identified from 31 family groups dominated by fish of the species Lutjanus gibbus, Lethrinus ornatus, Acanthurus mata, Naso thynnoides, and Lethrinus rubrioperculatus. Among those four dominant reef fish species, Lutjanus gibbus is in fully exploited utilization status with an SPR value of 0.26 or 26%. Meanwhile, the other three types of reef fish are under-exploited with SPR values above 0.3 or 30%. Keywords: fishing, Lc, length-based approach, Lm, SPR.

Snapper is one of the economically important fish targeted by fishers in the island of Timor. Domestic and foreign markets for fillet and fresh snapper is considerably large. The export volume in 2021 was 4,172,056 kg, and the total value reached 12,452,211 USD. Along with the increasing snapper production in Kupang City and NTT, it is necessary to forecast the future snapper production. Thus, it can be a reference for policy makers in the region in designing fisheries development. This study aims to produce forecasting model for snapper catches at PPI Oeba Kupang. This research applied Autoregressive Integrated Moving Average (ARIMA) and Seasonal Autoregressive Integrated Moving Average (SARIMA), as a forecasting method. The data of snapper production analyzed in this study consisted of 72 months, started from January 2016 to December 2021. Data were obtained from the UPT of the Department of Marine and Fisheries of NTT Province at PPI Oeba Kupang. Data have a non-stationary pattern to the variance, hence a logarithmic transformation is needed, as well as seasonal differences analysis. However, there is no need for non-seasonal differences since the data are stationary with respect to the mean. The results of the identification of the Autocorrelation function and Partial Autucorrelation function Plots are ARIMA models with seasonal factor period 4, ARIMA (P,D,Q) = (1,0,1), while the SARIMA order (P, D, Q) = (2,1,1)4. Based on parameter testing, verification, examination, and testing of suitable models, the best model obtained was (0,0,1)(2,1,1)4. Keywords: Autoregressive Integrated Moving Average, focecasting model, Seasonal Autoregressive Integrated Moving Average, Snapper.

One of the challenges in managing small-scale fisheries with limited data is the need for indicators to estimate the stock status and the total allowable catch for sustainable utilization of fish resources. This study aims to estimate the stock status, catch, and optimal fishing effort of the grouper fishery in Saleh Bay, West Nusa Tenggara Province by using the Length-based Spawning Potential Ratio analysis, production surplus model, and bioeconomic approach. Based on the results of this study, it is known that Plectopomus leopardus and Epinephelus coioides are in overexploited condition, while Plectropomus maculatus is in fully exploited status. This study also shows that with a bioeconomic approach, optimal conditions for grouper fisheries in these waters are achieved when the catch is 3,862.1 tonnes per year. The results of this study underline the importance of maximum economic yield-based management as a framework for a fishing quota-based system as an additional instrument in implementing sustainable fishery management in the future. The success of applying the quota system and the total allowable effort is determined by the accuracy of the catch data of small vessels around Saleh Bay under regulatory provisions, supervision and effective law enforcement, the socio-cultural conditions of local communities and the level of compliance with regulations.Keywords: fishing effort, grouper, overfished, quota system.

Snappers (Lutjanus spp.) are the most common reef fish caught in Taka Bonerate National Park due to its high economic value and primarily targeted species. Without proper management measures, intensive fishing activities might result in unsustainable fish stocks. Therefore, in order to maintain sustainable utilization, it is important to understand the stock status of snapper fisheries. This study aimed to analyze the snappers' stock status in Taka Bonerate National Park's waters. Data were collected from January to December 2022 at three small-scale fisheries landing sites. The results showed that snappers are classified as slow-growing species with growth rates for species L. bohar, L. quinquelineatus, L. gibbus respectively 0,12, 0,39, and 0,35 per year to reach their respective asymptotic lengths of 83,41 cm, 29,5 cm, and 46,80 cm. The stock status of L. gibbus and L. bohar were indicated at overfished status where the exploitation rate (E) was > 0.5 and the SPR was < 0.3, hence a proper management measures is required. Furthermore, the species of L. quinquelineatus has a value of E is 0.5 and SPR is at 0.3, indicating that the utilization level of this species was at an optimal level.

Increasing of fishing pressure poses a serious threat to the sustainability of blue swimminng crab resources. Trap design modifications are needed to improve size selectivity and to release under size crabs. This study aimed to determine the type of wall modification of collapsible trap that is effective in excluding under size blue swimming crab. Laboratory observations were conducted using four escape vents treatments and three different mesh sizes. The escape gap used are rectangular, square, circular and oval respectively. Moreover, the mesh sizes used are 2.0 inches, 2.5 inches and 3.0 inches. Descriptive analysis and scoring were used to determine the most effective type of wall trap modification to be used in the blue swimming crab fishing. The results showed that the rectangular escape gap has better effectiveness than other shapes with the percentage of crabs that pass through at 86.7%. The wall modification using a 3.0-inch mesh size had better performance than the other modification types with a total score of 19. Collapsible trap with a 3.0-inch mesh wall was able to escape 86.7% of the crabs with an escape time of only 11.2 seconds and an average escaped crab carapace width of 78 mm.
