Abstract

ABSTRACTThe introduced freshwater ornamental fish commodity which is a favorite in the international market with relatively stable prices in the market is the koi fish Cyprinus rubrofuscus. The average increase in koi fish production is 11,6% every year. The koi fish observed were showa. The broodstock of koi fish are fed in the form of Shoori Superior Koi Food Spirulina variant with the ad satiation method. The average eggs produced in spawning were 288,300 eggs with FR 78,3%, and HR 87,98%. Koi fish hatchery activities produce 2-3 cm larvae in 14 days and produce 5-10 cm in 45 days. Mina Karya Koi is able to produce quality larvae and seeds as many as 147,000 tail of fish for a year with an SR (Survival Rate) produced for 45 days of 85,6%. This hatchery activity has an R/C ratio of 2,5 with a selling price of larvae of Rp150 000 per kg and a selling price of seeds of Rp3 000 per tail of fish.Key words : Koi Fish, Cyprinus rubrofuscus, Hatchery ABSTRAKKomoditas ikan hias air tawar introduksi yang menjadi favorit di pasar internasional dengan harga relatif stabil di pasar adalah ikan koi Cyprinus rubrofuscus. Kenaikan rata-rata produksi ikan koi sebesar 11,6% per tahun. Ikan koi yang diamati adalah ikan koi jenis showa. Induk ikan koi diberikan pakan berupa Shoori Superior Koi Food varian Spirulina dengan metode ad satiation atau sekenyangnya. Rata-rata telur yang dihasilkan dalam pemijahan yaitu sekitar 288.300 butir telur dengan FR 78,3%, dan HR 87,98%.

Abstract

Aquaponics is the cultivation of fish and plants in a series of systems, either in one container or in separate containers, by paying attention to the balance between fish, plants, and aquatic microorganisms. One of the obstacles in aquaponic activities is that vegetable growth is not optimal due to a lack of dissolved nutrients, so further research is needed to make better plant growth. This study aimed to evaluate catfish and water spinach growth performance in an aquaponic system by adding AB mix nutrients at different fish stocking densities. This study used a completely randomized design with three differences in stocking densities of catfish (150 fish/m3, 200 fish/m3, and 250 fish/m3) as test animals with four replications where AB mix was added to each treatment. The growth performance of catfish is better in control with a stocking density of 250 fish/m3 and without adding nutrients. The growth performance of catfish decreased with the addition of AB mix nutrients, while the growth of water spinach was better. The growth rate of catfish without adding AB mix nutrients was higher than in other treatments. In contrast, all treatments with the addition of AB mix increased the growth performance of water spinach, with the stocking density of catfish not affecting the growth of water spinach plants. Keywords: aquaponics, water spinach, catfish, growth ABSTRAK Akuaponik merupakan budidaya ikan dan tanaman dalam satu rangkaian sistem, baik dalam satu wadah maupun dalam wadah terpisah dengan memperhatikan keseimbangan antara ikan, tanaman dan mikroorganisme perairan. Salah satu kendala sistem akuaponik adalah pertumbuhan sayuran yang tidak optimal karena kurangnya nutrisi terlarut. Tujuan dari penelitian ini untuk mengevaluasi performa pertumbuhan lele dan kangkung dalam sistem akuaponik dengan penambahan nutrisi AB mix dan pada padat tebar ikan yang berbeda. Penelitian menggunakan rancangan acak lengkap dengan tiga perbedaan padat tebar ikan lele (150 ekor/m3, 200 ekor/m3, dan 250 ekor/m3) sebagai hewan uji sebanyak empat ulangan di mana nutrien AB mix ditambahkan disetiap perlakuan. Kinerja pertumbuhan ikan lele lebih baik pada perlakuan kontrol dengan padat tebar 250 ekor/m3 dan tanpa penambahan nutrisi AB mix. Performa pertumbuhan ikan lele menurun dengan adanya penambahan nutrisi AB mix, sedangkan pertumbuhan tanaman kangkung lebih baik. Laju pertumbuhan ikan lele dengan tanpa penambahan nutrisi AB mix lebih tinggi dibandingkan perlakuan lainnya, sedangkan semua perlakuan dengan penambahan AB mix meningkatkan performa pertumbuhan tanaman kangkung dengan jumlah padat tebar ikan lele tidak berpengaruh pada pertumbuhan tanaman kangkung.

Abstract

Pond bottom sediment conditions influence shrimp culture. As benthic organisms, shrimp are mainly on the surface of the pond bottom, so cultivation preparations related to improving sediment quality are essential. Pond bottom practice, such as drying, liming, and fertilizing, is common. However, in bottom pond conditions where total drying cannot be carried out, other treatments are needed, such as the addition of hydrogen peroxide. The purpose of this study was to determine the effect of adding hydrogen peroxide in pond sediments on the performance of shrimp growth and water quality. The study was conducted with five doses of hydrogen peroxide (0.25 mL, 0.5 mL, 1 mL, 2 mL) mixed with 350 g of pond soil sediment. Ten shrimps with an average weight of 0,27±0,03 g were put into the rearing container, which had been given pond bottom sediment according to the treatment. The results showed that the 2 mL hydrogen peroxide treatment gave the best results on the growth rate and average weight of Pacific whiteleg shrimp at the end of rearing. Water quality such as pH value, dissolved oxygen, and temperature were not significantly different between treatments. Hydrogen peroxide treatment can improve shrimp growth performance without affecting water quality during rearing.
