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

The freshwater lobster Cherax quadricarinatus is an aquaculture commodity with high economic value, yet it remains relatively unfamiliar to the general public. Nevertheless, market demand for this species has shown a significant upward trend, both domestically and internationally. In Indonesia, the increase of aquaculture production specially on freshwater lobster has not been sufficient to meet existing demand, primarily due to the limited availability of high-quality broodstock and the low reproductive capacity of female brood lobsters. One potential strategy to address this issue is the optimization of feed quality. This study aims to evaluate the effects of a dietary combination consisting of mung bean sprouts (Vigna radiata), white sweet potatoes (Ipomoea batatas), and commercial pellets enriched with vitamin E on the reproductive performance of female freshwater lobsters. The results indicated that the best feed formulation was observed in Treatment P3, which consisted of 25% mung bean sprouts, 50% Fengli 3 pellets + vitamin E, and 25% white sweet potatoes. This treatment accelerated gonadal maturation to 25 days and resulted in a fecundity of 467.33 eggs, a fertilization rate (FR) of 97.84%, a hatching rate (HR) of 92.70%, and a survival rate (SR) of 90.87%. The content of vitamins A, C, and E in mung bean sprouts is known to stimulate spawning and enhance embryo hatchability, while bioactive compounds in white sweet potatoes contribute to the synthesis of reproductive hormones such as estrogen and vitellogenin.
