Percobaan ini bertujuan untuk mengetahui pemijahan ikan betutu di kolain tanah dan kolarn beton. Ikan betutu (125 - 500 g per ekor) dipelihara selarna musim hujan dan musim kemarau dan diberi makan ikan teri sebanyak 7% setiap hari. Pada musim penghujan, pada kolam tanah dan kolam beton terjadi masingmasing 31 dan 30 kali pemijahan ikan betutu, Oxyeleotris marmorata (Blkr.), per sarang. Pada musim kemarau, hanya ikan betutu yang di kolam tanah saja yang memijah sebanyak 36 kali dengan rata-rata 39.170 butir per tahun per sarang.
