Abstract

West Sumatera has high fishery potential, particularly for macarel(Thunnus sp), whose presence is influenced by oceanographic factors such as sea surface temperature (SST), chlorophyll-a concentration, and ocean currents. This study aims to analyze the variability of SST, chlorophyll-a, and currents in West Sumatera waters, identify oceanographic indicators of upwelling events, and examine the relationship between upwelling and potential macarel fishing grounds. Using a qualitative survey approach and ArcGIS 10.8, spatial analysis was conducted to determine potential fishing zones. Results indicate SST fluctuated between 28.1°C (February 2023) and 30,4°C (July 2022), while chlorophyll-a showed seasonal variation, peaking at 0.40 mg/m³ in June 2022. Current patterns are influenced by monsoonal winds and global atmospheric phenomena, with stronger currents during the East season, promoting upwelling and marine productivity. Overlay analysis revealed weak to very weak upwelling occurring periodically. Despite the weak upwelling, West Sumatera remains a highly potential fishing area, supported by positive correlations between SST and chlorophyll-a with macarel fishing zones. Regression analysis shows SST and chlorophyll-a negatively affect macarelcatches, whereas currents have a positive influence. Overall, oceanographic variability significantly impacts fishing potential in West Sumatera.

Abstract

Natural feed plays a crucial role as a primary nutrient source that is easily digested and suitable for the physiological needs of larvae during early life stages. Nannochloropsis sp. is widely used as a main natural feed for larvae of various aquaculture commodities, making its stable and high-quality availability essential for hatchery success. This study aimed to evaluate Nannochloropsis sp. culture techniques at semi-mass and mass scales and to determine cell density as an indicator of feed quality. The study employed direct observation during the culture period and descriptive analysis of cell density and water quality. Culture procedures at both scales included tank preparation, seawater filling, inoculation, cell density measurement, and harvesting, with differences only in tank size and inoculum volume. Results showed that peak cell density on day five reached 42,326,000 cells/mL in the semi-mass scale and 39,400,000 cells/mL in the mass scale, followed by a decline on day six. The study concludes that the Nannochloropsis sp. culture technique applied at UPTD BPBALP Teluk Buo is effective in supporting phytoplankton supply for hatchery operations.

Abstract

This study determined the effects of dietary Rucah fish meal on the performance and protein efficiency ratio of local chickens. Two hundred day-old local chicks (initial BW: 42.4 g; CV: 7.48%) were raised for eight weeks and assigned to a completely randomized design (CRD) consisting of five dietary treatments with four replicates of 10 birds each. The treatments were as follows: T0 = diet containing 12% Rucah fish meal, T1 = diet containing 14% Rucah fish meal, T2 = diet containing 16% Rucah fish meal, T3 = diet containing 18% Rucah fish meal, and T4 = diet containing 20% Rucah fish meal. Feed intake, body weight gain, feed conversion ratio, protein intake, protein efficiency ratio, slaughter weight, and carcass percentage were also recorded. Data were analyzed using analysis of variance (ANOVA), and parameters showing significant effects were further analyzed using Duncan’s multiple range tests. The inclusion of Rucah fish meal from 12% to 20% did not significantly affect (P>0.05) any of the measured parameters, including feed intake, body weight gain, feed conversion ratio, protein intake, protein efficiency ratio, slaughter weight, and carcass percentage. Overall, the results of this study indicate that Rucah fish meal can be included in local chicken diets at levels up to 20% without any adverse effects on growth performance, protein utilization, or carcass yield, demonstrating its potential as a sustainable and locally available alternative protein source for poultry production.

Abstract

Boat seine gear is a fishing gear is classified as a purse seine that has high productivity, resulting in a high composition of catches. The composition of fish species in the body of water is used to predict species diversity to show the number of individuals or different types of fish due to differences in size, shape, and quantity. In addition to diversity, size distribution also functions to show the growth rate of fish based on length frequency in a body of water. The purpose of this study was to analyze the diversity and size distribution of catches from boat seines in the Carocok Tarusan Coastal Waters. A survei method was used in this study. A purposive sampling method was used for the sampling. The study showed that the total catch of boat seine was 433.904 fish weighing 899,86 kg, which was divided into main catch (HTU) and bycatch (HTS). The number of HTU catches of payang was higher (92.51%) than that bycatch of 7,49%. The diversity index value in the Carocok Tarusan Coastal Waters was 0,37, the uniformity index was 0,12 and the dominance index was 0,86. It can be concluded that the results of the diversity and uniformity index are relatively low while the dominance index value is relatively high. The distribution of anchovy size as the main result of payang, which is 64,74% is considered worthy of being caught

Abstract

Kerinci Lake is a type of tectonic lake located in the Kerinci Regency, Jambi Province. The fishing gear such as tangkul/ pesap, nets (trawls), and traps (lukah) are commonly used in Telago Village. This research aims to investigate the effect of soaking duration of trap fishing gear on the catch of freshwater lobster. This research was conducted from February 27 to March 18, 2024. An experimental fishing method was employed, comparing soaking durations of 24 hours and 12 hours. Quantitative data were analyzed using frequency of occurrence, followed by T-test analysis. The results showed that a 24-hour soaking period yielded 237 lobsters with an average weight of 34.75 grams, with the highest frequency of occurrence at 44% and the lowest at 24%, averaging 33.20%. In contrast, a 12-hour soaking period resulted in 119 lobsters with an average weight of 33.88 grams, with the highest frequency of occurrence at 32% and the lowest at 8%, averaging 17.60%. T-test analysis indicated no significant effect of soaking duration on the number of lobsters caught, average weight, or depth-related environmental parameters. However, significant effects were observed for environmental parameters such as temperature and pH. In conclusion, while soaking duration does not significantly affect the catch of freshwater lobster (Cherax quadricarinatus), the 24-hour soaking period resulted in a higher yield.

Abstract

Threadfin bream is a demersal fishery commodity landed at Belawan Ocean Fishing Port (PPS Belawan) and requires sustainable management due to fluctuations in fishing intensity. This study aimed to analyze the maximum sustainable yield, total allowable catch, utilization rate, and fishing effort rate of threadfin bream landed at PPS Belawan. The study was conducted from January 12 to 31, 2026, using secondary data on production and fishing effort from 2021 to 2025. The analysis included fishing gear standardization using the Fishing Power Index (FPI), Catch Per Unit Effort (CPUE) calculation, and maximum sustainable yield estimation using the Schaefer and Fox models. The results showed that bagged fish trawl (Jaring Hela Ikan Berkantong/JHIB) was selected as the standard fishing gear because it had the highest productivity. The Schaefer model estimated an MSY of 4,941.22 tons/year with an Fopt of 1,011.99 trips/year, while the Fox model estimated an MSY of 2,536.73 tons/year with an Fopt of 698.12 trips/year. The utilization rate ranged from 15% to 43%, with an average of 26%, indicating no production-based overfishing. However, fishing effort in 2024 and 2025 exceeded Fopt; therefore, fishing effort control is necessary.
