Kerang hijau Perna viridis merupakan komoditas perikanan yang sudah lama dibudidayakan di Indonesia. Perubahan larva kerang hijau dari planktonik menjadi sesil merupakan masa kritis untuk hidup larva kerang hijau. Penempelan kerang hijau memerlukan substrat yang baik agar benih kerang hijau menempel dengan sempurna dan tidak terbawa oleh arus. Pada proses budidaya kerang hijau diperlukan jenis substrat yang sesuai dengan bissus kerang hijau. Penelitian ini untuk mengetahui tingkat penempelan benih pada substrat dan pertumbuhan panjang benih kerang hijau. Penelitian dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan yaitu jenis substrat (tali) yang berbeda (serat alami, serat sintetis dan serat nanas). Penempelan benih kerang hijau yang paling tinggi pada minggu ke 8 jenis serat alami yaitu 92%, selanjutnya serat sintetis 30% dan serat nanas 14%. Panjang rata-rata benih kerang hijau yang paling baik pada serat alami yaitu 1,0 cm. Panjang rata-rata yang baik benih kerang hijau pada serat alami dapat disebabkan karena serat alami memiliki tekstur yang lembut yaitu seratnya terbuat dari beberapa jenis tumbuhan sehingga kerang hijau dapat menempel dengan baik. Berdasarkan uji lanjut BNT menunjukkan bahwa penggunaan berbagai jenis tali menghasilkan tingkat penempelan yang berbeda nyata.

Leucaena leaves is a potential ingredient for raw material feed of catfish. The aim of this study is to evaluate the effects of dietary fermented leucaena leaf on digestibility and hematological parameters of catfish. Four treatments and 3 replicates, namely: A (reference feed 70% + leucaena leaves meal 30%), B (reference feed 70%+fermented leucaena leaves meal with A. niger 30%), C (reference feed 70%+fermented leucaena leaves meal with R. oligosporus 30%), and feed D (reference feed 70%+fermented leucaena leaves meal with S. cerevisiae 30%) were used in this study. The juvenile catfish (initial weight was 5,45±0,16 g) are randomly distributed into eighteen tanks with 40 fish per aquarium. Each diet is randomly assigned to the triplicate aquarium and fed to fish three times a day up to satiation for 4 weeks. The results showed that fermented leucaena leaves treatments were significantly higher (P<0.05) than that control in final weight and feed conversion rasio. Nutrients digestibility and final weight were significantly highest (P<0.05) in fermented leucaena leaves with A. niger compared to the other treatment. The value of protein digestibility was significantly highest (P<0.05) in fermented leucaena leaves with A. niger (76,04%), followed by fermented leucaena leaves S. cerevisiae with (69,71%), fermented leucaena leaves meal with R. oligosporus (68,24%), and control (65,18). Leucaena leaves had no effect on physiological processes in catfish, as shown by hematological parameter values that were within the normal range.

Anesthetic method is an important component to support the activities of transporting live fish from one place to another for a long period of time. Cost efficiency and effectiveness of anesthetic ingredients that not cause residues in fish are factors to beconsidered as an anesthetic. Aim of this research is to study the effect of subletal concentration of amethyst leaf extract on the hematological conditions of tilapia fry after transporting on wet transportation systems. The research procedure was through the amethyst leaf extract toxicity test series (LC50-96 hours) to determine its sublethal concentration by 20% (0,297 ml/l), 30% (0,445 ml/l) and 40% (0,594 ml/l) of the LC50 value. The measured parameters are clinical symptoms, period of fainting and conscious recovery, hematological analysis, survival rate, and water quality. The results showed the concentration of amethyst leaf extract had an effect (P<0,05) on the period of fainting and the hematological component after transportation simulation. Results of water quality measurement showed the parameters of pH at 6 and ammonia 0,04 mg/l are not at the optimum value when fish transportation occur. The recommended concentration of amethyst leaf extract for use as an anesthetic agent is 0,445 ml/l
