Fisheries activities red snapper in Pinrang waters is considered to be a small scale and caught with that variety of types instrument catch fish (multi gears) one of them is bubu fishing gear. Now, the level of the utilization of red snapper is believed to have been experience symptoms of over fishing due to the high pressure in the area. The study aims to analyze the size structure and length-weight correlation of red snapper (Lutjanus sp). The study was conducted during 5 months of period, starting from March to July 2019 in Pinrang waters, Pinrang District. The sample of the fish obtained by fishermen using ‘Bubu’ fishing gear. The results showed that the total length structure of males and females of the red snapper was ranging from 32 - 57 cm, while the weight structure of males and females of the red snapper had a wide range from 500 to 2500 grams. The total sample of the red snapper is 163 divided into 68 males and 95 females. The growth pattern of red snapper can be categorized in a negative allometric type with a value of b = 2.3328 which means that the length increased faster than the weight gain.

Macrozoobenthos are bottom animals that play an important role in the productivity of waters in seagrass beds. This study aims to determine the species composition, density of macrozoobenthos, community structure of macrozoobenthos and the relationship between seagrass density and density of macrozoobenthos. The research method used is purposive sampling method, this method is taken based on certain reasons and criteria. This research was conducted in June-July 2022 on Barrang Lompo Island. Sangkarrang District, Makassar City. There were 26 species found consisting of 4 classes namely Bivalvia, Gastropods, Chepalopods and Crustacea with a total of 283 ind and dominated by the Gastropod class, both from the number of species and individual density. Macrozoobenthos community structure on Barrang Lompo Island at station I and II with a moderate diversity index (H'), moderate uniformity index (E') and low dominance index (D). The types of seagrass found at stations I and II were Enhalus acoroides, Thalassia hemprichii, and Cymodocea rotundata. The regression results of the relationship between seagrass density and macrozoobenthos density on Barrang Lompo Island show a weak relationship, which means that seagrass density has no relationship with macrozoobenthos density but macrozoobenthos density is influenced by physical and chemical factors of the waters and the type of sandy substrate.

Seagrass beds in the waters of Barrang Lompo Island and Kodingareng Lompo have their own characteristics, especially for the type of Thalassia hemprichii. The purpose of this study was to determine the morphometric characteristics of seagrass Thalassia hemprichii and the environmental conditions of the waters on Barrang Lompo Island and Kodingareng Lompo Island. This research was conducted in June-July 2022 in the waters of Barrang Lompo Island and Kodingareng Lompo Island. The research method used was purposive sampling. Morphometrics of seagrass Thalassia hemprichii on Barrang Lompo Island at station 1 average leaf length 10.88 cm, leaf width 1 cm, rhizome length 5 cm, root length 6.46 cm, number of roots 8. At station 2 leaf length measures 7.5 cm, leaf width 1 cm, rhizome length 7.84 cm, root length 6.64 cm and number of roots 5. Meanwhile on Kodingareng Lompo Island at station 1 the size of leaf length was 10.33 cm, leaf width 1 cm, rhizome length 4 cm , root length 4.33 cm and number of roots 5. At station 2 the size of leaf length was 9.63 cm, leaf width 1 cm, rhizome length 4.85 cm, root length 4 cm, number of roots 5. Morphometrics of seagrass Thalassia hemprichii on islands Barrang Lompo and Kodingareng Lompo islands did not show a significant difference. The environmental conditions of the waters on both islands are still in optimum conditions for seagrass growth for the parameters of current speed and brightness.

Ikan kakap merah Lutjanus malabaricus merupakan jenis ikan dari family Lutjanidae yang memiliki daerah  penyebaran cukup luas termasuk perairan Pinrang dan dapat tertangkap dengan berbagai jenis alat tangkap seperti rawai dasar, pancing ulur, dan bubu. Penelitian ini bertujuan untuk menganalisis hasil tangkapan kakap merah pada umpan yang berbeda sehingga upaya penangkapan kakap merah dapat lebih efektif dan efisien. Total 852 ekor kakap merah yang dikumpulkan secara acak dari alat tangkap rawai dasar, pancing ulur dan bubu di perairan Pinrang. Parameter yang diamati meliputi komposisi hasil tangkapan dan sebaran frekuensi panjang dengan menggunakan empat jenis umpan yaitu ikan teri, layang, tembang dan udang. Data yang diperoleh dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa hasil tangkapan kakap merah terbanyak diperoleh dari umpan udang sebanyak 305 ekor (36%)  dan paling sedikit dari umpan ikan layang yaitu sebanyak 143  ekor (16%). Begitupula dengan sebaran ukuran panjang kakap merah yang berkisar antara 17-67 cm dengan frekuensi tertinggi sebanyak 89 ekor pada kisaran ukuran panjang 57-67 cm dari umpan udang dan terendah 9 ekor berada pada kisaran ukuran panjang 17-26 cm dari umpan ikan layang. Penggunaan umpan udang dapat meningkatkan hasil tangkapan Ikan kakap merah Lutjanus malabaricus.

Terumbu karang mempunyai nilai dan arti yang sangat penting dari segi sosial, ekonomi maupun budaya, pemantauan tutupan terumbu karang penting dilakukan untuk mengetahui tingkat kesehatan ekosistem karang tujuan pengelolaan. Tanakeke merupakan salah satu gugusan kepulauan sebagian besar perairannya dikelilingi oleh ekosistem terumbu karang yang dimanfaatkan oleh nelayan sebagai area Fishing Ground  untuk menangkap ikan dan sebagai alur pelayaran transportasi kapal. Namun beberapa penelitian yang telah terpublikasikan sebelumnya lebih fokus pada komunitas ikan di sekitar terumbu karang. Penelitian ini bertujuan untuk mengetahui kondisi tutupan karang dengan menggunakan Metode Point Intercept Transect (PIT), metode ini merupakan salah satu metode yang dikembangkan untuk memantau kondisi karang hidup dengan cara menghitung persen tutupan substrat dasar secara acak. Penelitian ini dilakukan pada Bulan Oktober 2021. Hasil penelitian menunjukkan bahwa ekosistem terumbu karang yang berada di Perairan Kepulauan Tanakeke khususnya di sebelah timur-timur laut, di sebelah barat laut, dan di sebelah timur laut Kecamatan Kepulauan tergolong karang rusak, karang baik, dan karang sedang. Pada stasiun 1, tutupan karang jenis Acropora sebesar 18% dan tutupan karang jenis Non-Acropora sebesar 22%.  Pada stasiun 2, tutupan karang jenis Acropora sebesar 70% dan tutupan karang jenis Non-Acropora sebesar 18%.  Sedangkan pada stasiun 3, tutupan karang jenis Acropora sebesar 28% dan tutupan karang jenis Non-Acropora sebesar 48%.
