Abstract

Effective fishery management is essential for sustaining fish resources, economic growth, and social well-being. Achieving optimal and sustainable exploitation levels requires determining key metrics: biomass, optimal effort, catch, and costs under various management regimes (sole owner/open access, MSY, MEY, and dynamic). This study aims to determine the optimal and sustainable management level of red snappers (Lutjanus spp.) in the waters of Makassar City. This research uses a quantitative analysis method with a bio-economic analysis technique. The research was conducted in the waters of Makassar City from June to December 2022. The bio-economic analysis indicates that red snapper production in Makassar waters can be further optimized, but current fishing efforts exceed the optimal limit, requiring improvements in the catch effectiveness and efficiency of the catch. The high fishing effort for red snapper in this area indicates inefficient fishing activities, which suggest the potential for fishing optimization. To reach the Maximum Sustainable Yield (MSY), the current fishing effort, which has reached 163,496 trips, must be reduced by 78,902 trips, or around 48.26%, to reach the optimal fishing point. Similarly, to achieve The Maximum Economic Yield (MEY), the fishing effort must be reduced by 90,925 trips, or approximately 55.61%.

Abstract

This study aimed to determine the morphometric performance of polled Bali cattle aged 12-15 months and the influence of the cows on the morphometrics of breeding cattle.The research material consisted of 120 head Bali cattle divided into 40 head polled cattle, 40 head with horns, and 40 cows with horns. The study was conducted in Barru District, South Sulawesi Province. The study parameters consisted of withers height, body length, and heart girth. The data were statistically analyzed using the independent sample t-test, and the effect of the morphometrics of the cows on the calves was analyzed using simple regression analysis. Measurement data were analyzed using the IBM SPSS Statistics application. The results showed a very significant difference in the body length of polled and horned males (p<0.01). Significant differences were also found in withers height and body length between polled and horned female calves (p<0.01). Polled Bali cattle aged 12-15 months have a larger morphometric size than those with horns. It is hoped that identifying the superiority of polled Bali cattle will continue at different age statuses to compile information as material for the Indonesian National Standard for hornless Bali cattle.
