Abstract

Observations on pelagic fish catch activities using bagan Rambo in Makassar Strait had been conducted in 2005and 2006 to obtain physical, chemical, and biological data and their processes in the operation of bagan Rambo inthe observation sites. The objective of the study was to overcome the overfishing problems which have beenhappenning in Makassar Strait, using a model of the trophic level approaches. Nine observation stations were setin three transects perpendicular to the coast. The measurement of physical, chemical, and biological parameterswere conducted monthly. Biological parameters measured were chlorophyll-a, and the abundance of phytoplanktonand zooplankton. Phytoplankton primary productivity, grazing mortality of phytoplankton by zooplankton, numberof catch of fish, and fish feeding habit were also measured. Run of the built model based on the data obtainedshowed that with the present catch-pressure (assuming that this was the start of catching operation), there wouldbe an overfishing starting in the 26 th or 27th month onward. Meanwhile, if the catch were half of the present, thenthere would be an overfishing in the 31 st or 32nd month, but would back to the sustainable production months afterthat. The model is still being developed by finding and adding more accurate data and parameters.

Abstract

Tujuan penelitian ini adalah untuk membandingkan kandungan klorofil-a, kelimpahan fitoplankton, zooplankton, dan beberapa nilai parameter lingkungan berdasarkan bulan pengamatan selama periode Mei sampai dengan Agustus 2021. Manfaat penelitian diharapkan dapat memberikan informasi dasar tentang penyebaran klorofil-a, kelimpahan fitoplankton, kelimpahan zooplankton, dan parameter lingkungan untuk dijadikan pertimbangan dalam pengelolaan perikanan tangkap. Penelitian dilaksanakan mulai Mei sampai dengan Agustus 2021 di perairan Pantai Kabupaten Pinrang, Provinsi Sulawesi Selatan. Penelitian ini terbagi menjadi beberapa tahap yang meliputi tahap persiapan, penentuan stasiun, dan pengambilan sampel, pengukuran parameter fisika dan kimia perairan, identifikasi dan pencacahan fitoplankton, analisa data serta analisa stastistik. Analisis statistik yang digunakan adalah Analisis One Way Anova, Uji lanjut Post-Hoc Test menggunakan metode Tukey untuk membandingkan rata-rata kelimpahan antar stasiun. Hasil analisis menunjukkan bahwa pada Mei sampai dengan Agustus di perairan pesisir Kabupaten Pinrang kandungan klorofil-a relatif homogen, rata-rata kelimpahan fitoplankton pada Agustus lebih tinggi dibandingkan pada bulan Juni dan Juli, kelimpahan zooplankton relatif homogen selama bulan Mei sampai dengan Agustus. Rata-rata salinitas dan pH berbeda nyata antar bulan pengamatan, sedangkan suhu dan kadar DO tidak berbeda nyata antar bulan pengamatan.
