Daftar Isi:
- Respons fisiologi mata ikan selar (Selaroides leptolepis) dan ikan kembung (Rastroliger brachysoma) berbeda untuk setiap warna cahaya. Respons fisiologi mata ikan bisa dijadikan indikator dalam menentukan tingkat ketertarikan ikan terhadap warna cahaya tertentu. Penelitian ini bertujuan untuk mengidentifikasi tingkat ketertarikan ikan selar dan ikan kembung terhadap cahaya warna putih, kuning, hijau dan biru. Metode penelitian menggunakan metode percobaan yang dilakukan di bagan tancap. Sepuluh ekor ikan selar dan ikan kembung yang dibatasi dengan jaring diberi cahaya selama 30 menit. Sampel ikan yang telah diberi perlakuan cahaya diambil matanya dan dilakukan analisis histologi. Analisis data yang digunakan dalam penelitian ini adalah analisis regresi ukuran ikan, indeks sel kon dan kecepatan pergerakan sel kon. Hasil penelitian menunjukkan bahwa ikan selar sangat tertarik terhadap cahaya LED warna hijau dan biru, sedangkan ikan kembung tertarik terhadap cahaya warna biru. Rata-rata indeks sel kon ikan selar pada cahaya warna biru dan hijau adalah 77,3±7,4% dan 70,7±6,8%, sedangkan rata-rata indeks sel kon ikan kembung yang diberi cahaya warna biru adalah 79,9±2,0%. Kecepatan rata-rata pergerakan sel kon ikan selar yang diberi cahaya biru mencapai 0,0180±0,0028 μm/det, sedangkan ikan kembung dengan cahaya hijau adalah 0,0157±0,0018 μm/det. Berdasarkan hasil penelitian dapat disimpulkan bahwa ikan selar sangat tertarik terhadap cahaya warna hijau dan biru, sedangkan ikan kembung sangat tertarik terhadap cahaya warna biru.
- The physiological response of the eye yellow-striped scad (Selaroides leptolepis) and short mackerel (Rastreliger brachysoma) are different for each color of light. The physiological response of the eye fish can be used as an indicator to determine the level of attraction of fish to specific colors of light. This study aims to identify the level of attraction of yellow-striped scad and short mackerel to light white, yellow, green and blue. The research was performed by experiment on lift net. Ten individual yellow-striped scad and short mackerel caged with a net. The fish lighted for 30 minutes. Then the fish was taken the eye, and histological analysis carried out. Data analysis used in this research were regression of fish size, con cells index and speed of con cells movement. The results showed that yellow-striped scad was very responsive to green and blue light. The short mackerel was more responsive to blue light. The average con cells index of yellow-striped scad for blue and green light were 77.3±7.4% and 70.7±6.8%, respectively. On the other hand, the average con cells index of short mackerel for blue light was 79.9±2.0%. The average speed of con cells movement of yellow-striped scad for blue light was 0.0180±0.0028 μm/sec, and the short mackerel for green light was 0.0157±0.0018 μm/sec. Based on the result of study can be conclouded that the yellow-striped scad was very attracted in green and blue light, while short mackerel was very attracted to blue light.
