Abstract

Perairan Samudra Hindia Timur memiliki keanekaragaman lobster yang tinggi, di mana Indonesia menjadi habitat bagi 6 dari 19 spesies Panulirus yang ada di dunia. Wilayah barat Pulau Sumatra, yang termasuk dalam kawasan ini, memiliki potensi besar dalam perikanan lobster. Penelitian ini bertujuan untuk mengkaji komposisi spesies, distribusi panjang karapas dan berat lobster beserta pola pertumbuhannya, serta menilai kesesuaian hasil tangkapan dengan ketentuan PERMEN KP No. 16 Tahun 2022 di perairan Sumatra Barat dan Pulau Tello, Sumatra Utara. Analisis yang digunakan meliputi identifikasi spesies, komposisi, distribusi frekuensi, chi-square, ANOVA satu arah, dan regresi. Hasil menunjukkan bahwa di perairan Sumatra Barat ditemukan enam spesies lobster, dengan Panulirus homarus (lobster pasir) sebagai spesies dominan, sedangkan di Pulau Tello ditemukan empat spesies, dengan dominasi P. versicolor (lobster bambu). Distribusi panjang karapas tertinggi di Sumatra Barat terdapat pada kisaran 8–9 cm (442 ekor), dan berat pada 220–360 gram (529 ekor), dengan pola pertumbuhan alometrik negatif. Di Pulau Tello, panjang karapas terbanyak berada pada kisaran 12–13 cm (30 ekor), dan berat pada 500–640 gram (25 ekor), juga menunjukkan pertumbuhan alometrik negatif. Seluruh komposisi lobster yang tertangkap di kedua lokasi dinilai layak tangkap berdasarkan ketentuan regulasi yang berlaku.   The East Indian Ocean holds significant potential for lobster diversity, and Indonesia is home to 6 of the 19 Panulirus species found globally. West Sumatra, located within this region, has promising lobster resources. This study aimed to assess species composition, carapace length and weight distribution, growth patterns, and compliance with fishing regulations (PERMEN-KP No. 16/2022) in the waters of West Sumatra and Tello Island, North Sumatra. Analytical methods included species identification, composition analysis, frequency distribution, chi-square testing, one-way ANOVA, and regression analysis. Findings revealed that six lobster species were identified in West Sumatra, dominated by scalloped spiny lobster (P. homarus), while four species were found on Tello Island, with painted spiny lobster (P. versicolor) being most abundant. In West Sumatra, the dominant carapace length class was 8–9 cm (442 individuals), and the most common weight class was 220–360 g (529 individuals), both exhibiting a negative allometric growth pattern. Meanwhile, Tello Island lobsters showed a dominant carapace length of 12–13 cm (30 individuals) and weight range of 500–640 g (25 individuals), also with negative allometric growth. Overall, the lobster catch composition from both locations was found to comply with the sustainable capture guidelines outlined in PERMEN-KP No. 16/2022.

Abstract

Jatigede Reservoir is one of the multi-functional reservoirs located in Sumedang Regency, West Java, Indonesia. The utilization of Jatigede Reservoir by the community caused ecological pressures that have resulted in a decrease in water quality and fisheries sustainability. The purpose of this study was to evaluate water quality parameters in Jatigede Reservoir to support a sustainable fisheries ecosystem. Sampling was done using purposive sampling and analysis using comparative descriptive. The results showed that the water temperature ranged from 26-29oC, pH 7.9-8.4, and dissolved oxygen 4-5.3 mg/L which still supports fisheries activities. The parameters of light transparency ranged from 0.19-1.1 m, total phosphorus 0.047 - 0.161, and chlorophyll-a 11 - 116 mg/m3 which exceeded the established quality standards. So it is necessary to manage and control pollution in Jatigede Reservoir to improve water quality and support the sustainability of the fisheries ecosystem.

Abstract

Perubahan kualitas perairan Sungai Kresek dipengaruhi oleh masukan berupa limbah industri, kegiatan domestik ataupun kegiatan pertanian. Limbah yang dihasilkan teridentifikasi sebagai limbah logam berat Cu dan Cr total. Sudut pandang toksikologi menyebutkan bahwa Cu dan Cr total dapat mempengaruhi fungsi organ pada organisme ikan.  Paparan logam berat Cu dan Cr terhadap insang secara terus menerus menyebabkan terjadinya pendarahan dan pemecahan pada sel insang. Kerusakan jaringan insang ikan dapat dianalisis sebagai proses biomonitoring kesehatan lingkungan perairan. Agen biomonitoring yang dilakukan dalam proses analisis adalah G. affinis. Penelitian ini bertujuan untuk menganalisis kerusakan jaringan insang G. affinis sebagai akibat adanya pencemaran logam berat Cu dan Cr total di Sungai kresek. Metode penelitian yang digunakan adalah metode deskriptif dengan pendekatan survei. Hasil analisis menunjukkan bahwa konsentrasi logam berat Cu pada sampel air didapatkan kisaran 0,13-0,24 ppm. Sedangkan nilai konsentrasi logam berat Cr total pada sampel air didapatkan kisaran 0,16-0,32 ppm. Berdasarkan konsentrasi tersebut, analisis jaringan insang G. affinis ditemukan jenis kerusakan berupa edema, hiperplasia dan fusi lamela. Hasil analisis parameter kualitas air, ditemukan nilai parameter suhu dan BOD berada di atas nilai baku mutu yang sudah ditentukan. Kesimpulan dari hasil penelitian menunjukkan bahwa Sungai kresek mengalami pencemaran logam berat Cu dan Cr total sehingga menyebabkan kerusakan jaringan insang G. affinis.   Inputs influence changes in the quality of the waters of the Kresek River in the form of industrial waste, domestic activities, or agricultural activities. The resulting waste was identified as Cu and Cr total heavy metal waste. The toxicological point of view states that Cu and total Cr can affect organ function in fish organisms. Continuous exposure to the heavy metals Cu and Cr in the gills causes bleeding and breakdown of the gill cells. Damage to fish gill tissue can be analyzed as a process of biomonitoring the health of the aquatic environment. The biomonitoring agent used in the analysis process is G. affinis. This study aims to investigate the damage to the gill tissue of G. affinis due to Cu and total Cr heavy metal contamination in the Kresek River. The research method used is a descriptive method with a survey approach. The analysis results showed that the heavy metal Cu concentration in the water samples was in the range of 0.13-0.24 ppm. Meanwhile, the total Cr heavy metal concentration value in water samples was found in the 0.16-0.32 ppm range. Based on these concentrations, analysis of the gill tissue of G. affinis found types of damage in the form of edema, hyperplasia, and lamella fusion. The results of the study of water quality parameters, it was found that the parameter values for temperature and BOD were above the predetermined quality standard values. The research results concluded that the Kresek River was polluted by heavy metals Cu and total Cr, which caused damage to the gill tissue of G. affinis.
