“…According to Nuraini and Hartati (2006), the operation of pots at coastal water fewer than 15 m catches 60% of the size of the fry. Grouper in immature gonad conditions caught in fishing ground pots of 62.5% is influenced by the depth of the waters because, in general, young groupers live in coral coastal waters with a depth of 0.5-3 m while stepping on adults migrate to the waters, which is 7-40 m deep (Tadjuddah et al 2013). Catching with pot fishing gear or pot contributes quite a lot to catching the average grouper a size below the adult (Agustina et al 2018).…”

Pot fisheries are one of the dominant activities of capture fisheries in the Penaah waters of Lingga, Riau Archipelago. This study aims to determine the effect of red LED lamp attractors on the fish catches of pots and identify the fish species. This study was conducted in the waters of Pena'ah Village, Senayang District, Lingga Regency, Riau Islands, using an experimental method. Data were collected from 18 pots for 18 days. There were three treatments, namely pot without using bait as a control, pot with red LEDs light, and pot with red LEDs light and bait, in which a total of six units of pots on each treatment. The pots caught 18 groupers during the study, of which nine individuals were captured by the pot with a red LED and bait, five individuals by the pot with a red LED pot, and four individuals without bait. The effectiveness analysis showed that the pot with red LED and bait was the highest (50%), the pot with red LED had a value of 28%, and the lowest was trapped without bait with an effectiveness value of 22%. The total catches of the pot based on the economic fish showed that adding a red LED attractor gave more types of catch than control. The red LED attractor is expected to be a solution to increase the effectiveness of the pot.

“…Perairan Wangi-Wangi dan Kaledupa merupakan salah satu perairan zona pemanfaatan bahari Taman Nasional Wakatobi (TNW). Sumber daya perikanan kerapu di perairan ini merupakan target utama penangkapan, termasuk kedua jenis tersebut (Tadjuddah et al, 2013). Ukuran ikan yang ditangkap umumnya disesuaikan dengan permintaan pasar yaitu ikan dengan bobot antara 500-˃1000 gram.…”

Abstrak : Penelitian ini bertujuan untuk mengeksplorasi hubungan panjang berat dua spesies ikan kerapu hermafrodit, yaitu kerapu sunu (Plectropomus leopardus) dan kerapu macan (Ephinephelus fuscoguttatus). Sebanyak 1.263 individu ikan yang terdiri dari 609 dan 654 spesies pertama dan kedua, masing-masing dikumpulkan dari perairan Wangi-Wangi dan Karang Kaledupa Taman Nasional Wakatobi selama September 2018 hingga Februari 2019. Ikan dikumpulkan secara acak yang merupakan hasil tangkapan pancing dan tombak. Hasil kedua spesies menunjukkan pola pertumbuhan alometrik (p <0,01 untuk keduanya) di mana nilai b masing-masing adalah 2,46 dan 2,73. Berdasarkan koefisien korelasi (R2), ditemukan bahwa variasi berat mampu menjelaskan 90% lebih panjang tubuh ikan. Berdasarkan panjang ikan saat tertangkap dan panjang pertama kali matang gonad, ditemukan bahwa betina P. leopardus sebagian besar ditangkap sebelum matang gonad (> 70%), sedangkan E. fuscoguttatus untuk kategori yang sama berada pada persentase yang lebih rendah (<50%). Langkah-langkah pengelolaan pada spesies hermafrodit dapat difokuskan pada proporsionalitas antara betina dan jantan terhadap keberhasilan reproduksi.Kata Kunci : Panjang Berat, E. fuscoguttatus, P. leopardusAbstract : The present research was aimed to explore the length-weight relationship-based growth of two hermaphrodite groupers, leopard coral grouper (Plectropomus leopardus) and tiger grouper (Ephinephelus fuscoguttatus). A total of 1,263 individual fishes comprising 609 and 654 individuals of these two species respectively, were collected from Wangi-Wangi and Kaledupa reef in Wakatobi National Park from September 2018 to February 2019. Fish were randomly sampled from catches that used hook-and-lines and spears. The results found that both species follow allometric growth patterns (p<0,01 for both) of which b values were, respectively, 2,46 and 2,73. Based on coefficient correlation (R2), it was found that weight variability is able to explain more than 90% of length. By comparing length at catch and length at first maturity, it was found that females of P. leopardus were largely caught at pre-mature stage (>70%), while for E. fuscoguttatus <50% of females were pre-mature. We suggest that management measures for hermaphrodite species should focus on the proportionality between females and males towards their reproductive success.Keywords : Length-weight relationship, E. fuscoguttatus, P. leopardus
