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

Dalam kegiatan budidaya perikanan banyak menggunakan pakan alami yaitu fitoplankton untuk memacu pertumbuhan organisme budidaya. Diatom adalah jenis fitoplankton yang sangat penting pada ekosistem perairan budidaya karena memiliki kandungan nutrisi yang baik, tidak menyebabkan penurunan kualitas air, dan keberadaannya tidak berdampak negatif pada lingkungan. Untuk pertumbuhan diatom skeletonema costatum dibutuhkan nutrien yang mengandung  silikon (Si) dan nitrogen (N). Penelitian ini bertujuan mengeksplorasi rasio optimum kebutuhan Si dan N untuk pertumbuhan diatom. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dengan masing-masing 3 ulangan yaitu  perlakuan A (kontrol) = rasio Si/N = 1:1, B = rasio Si/N = 2:1, C = rasio Si/N = 1: 2, dan D = rasio Si/N = 1: 4. Variabel yang diamati adalah kualitas air yakni pH, suhu, salinitas DO, nitrogen (NH3-N; NO3-N; NO2-N), silika (SiO2), fosfat (PO4), dan kepadatan sel diatom serta kandungan nutrisi (analisis proksimat) yang meliputi protein, karbohidrat, dan lemak. Hasil analisis ANOVA menunjukkan perbedaan pengaruh perlakukan rasio Si/N terhadap padat sel skeletonema costatum yang terjadi sejak hari ke-1 hingga hari ke-8. Perubahan kualitas air sangat jelas khususnya untuk parameter NH3-N dan NO3-N pada perlakuan C dan D.  Rasio di mana Si ditemukan sebagai faktor pembatas didapatkan pada Si/N = 1:4 dan rasio optimum dan efisien pada perlakuan Si/N= 1:1. Dari hasil ini diharapkan dapat memperkaya informasi khususnya peran rasio Si/N untuk pertumbuhan diatom pada skala laboratorium maupun dalam manajemen lingkungan untuk kegiatan budidaya. In aquaqulture activity, many use natural foods such as phytoplankton to stimulate the growth of culutured organism. Diatom is a type of phytoplankton that is very important in aquatic ecosystem because it has good nutritional content. It does not cause a decrese in water quality and its presence doesn not have a negative impact on the environment. For diatom growth skeletonema costatu, it requires nutrients containing Silicon (Si) and nitrogen (N). This study aimed to explore the optimum ratio of Si and N requirements for diatom growth. The study employed a Completely Randomized Design (CRD) with 4 treatments, each replicated 3 times: Treatment A (control) = Si/N ratio of 1:1, B = Si/N ratio of 2:1, C = Si/N ratio of 1:2, and D = Si/N ratio of 1:4. The variables observed were water quality including pH, temperature, salinity, dissolved oxygen (DO), nitrogen (NH3-N; NO3-N; NO2-N), silicate (SiO2), phosphate (PO4), diatom cell density, also nutrient content (proximate analysis) including protein, carbohydrate, and fat. ANOVA analysis result showed differences in the influence of treatment Si/N  ratio on the cell density of skeletonema costatum from day 1 to day 8. Clear changes in water quality were observed, especially for NH3-N and NO3-N parameters in treatments C and D. The limiting factor for growth was observed at Si/N = 1:4, while the optimum and efficient ratio was found in treatment Si/N = 1:1. This result  expected to enrich information, especially regarding the role of the Si/N ratio for diatom growth on a laboratory also in environmental management for cultivation.
