“…Beberapa faktor yang mendukung nilai jual ikan nila secara komersial antara lain keunggulannya antara lain dapat tumbuh di tambak udang yang sudah lama dengan salinitas tinggi (0,5-30 ppt), mudah dibudidayakan, mudah beradaptasi, pertumbuhan cepat, mampu memakan segala jenis pakan (omnivora), dan memiliki kemampuan beradaptasi yang tinggi terhadap berbagai kondisi (Rachmawati et al, 2018). Budidaya ikan nila saline, sama seperti budidaya udang vannemi, menghasilkan keuntungan yang lebih tinggi dibandingkan dengan budidaya pada media air tawar (Scabra et al, 2023).…”

Keberhasilan kegiatan budidaya ikan nila harus dibantu dengan bahan pendukung. Salah satu bahan yang potensial adalah daun mangrove Api-api. Tujuan penelitian adalah mengetahui dosis yang optimal dan pengaruh pemberian ekstrak daun mangrove api-api terhadap laju pertumbuhan dan tingkat pemanfaatan pakan ikan nila. Hewan uji yang digunakan adalah ikan nila salin dengan ukuran 4-6 cm ± 0,72. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 ulangan dengan dosis penambahan ekstrak daun mangrove yaitu, 0 ppm/ kg pakan (A), 150 ppm/ kg pakan (B), 250 ppm/ kg pakan (C), 350 ppm/ kg pakan (D). Parameter yang diamati adalah SGR, EPP, SR dan kualitas air. Ikan nila salin diberikan pakan sebanyak 7% dari biomassa ikan per hari dan frekuensi pakan sebanyak 3 kali sehari selama 35 hari. Hasil penelitian menunjukkan bahwa ikan nila salin yang diberi pakan dengan penambahan ekstrak daun mangrove api-api 150 ppm/ kg pakan menghasilkan Laju pertumbuhan tertinggi pada perlakuan B sebesar 4,66%, EPP 80,00%. SR 100%. Kualitas air suhu 27.3-28,6 0C, pH 5,5-6,3, salinitas 14-15 ppt dan DO 6,8-7,9 ppm.

“…The WG in the body might be due to digestive enzymes, which are also responsible for protein and lipid digestibility and making more P available from phytate. Relative growth, PER, FI, and FCR increased after the addition of phytase 53,66,80 . Besides, the supplementation of feed with phytase has shown improvement in the growth performance of several fish such as African catfish ( Clarias gariepinus ), 57 L .…”

Fishmeal is the most preferred protein source in aquafeed industry due to its balanced amino acid and fatty acid profile, but its limited global supply and high price value, necessitates researchers to focus on sustainable alternative sources of protein and plant‐based feed, to meet the growing demand of fish feed. Phytate is a reservoir of phosphorus present in the plants; however, its chelating ability makes it anti‐nutritional. Phytate forms complexes with minerals, proteins, lipids and carbohydrates, confining their accessibility in fish feeds, hence, additional dietary nutrients are required in the fish feed to overcome nutritional deficiencies. The elimination of phytate‐phosphorus through animal faeces and its pass on to aquatic bodies leads to enrichment of nutrients, eutrophication and algal blooms. Microbial phytase segregates phosphorus, minerals, proteins and lower inositol phosphates from phytate. The supplementation of fish feed with microbial phytase enhances the digestibility of minerals, due to which less nutrients are excreted in the faeces; therefore, minimizing pollution in water bodies. Monogastric and agastric animals inherently exhibit the deficiency of phytase; hence, supplementation of dietary material with phytase has been an emerging choice to make dietary nutrients available for fish. Moreover, microbial phytases have a broad pH range and are thermostable, which makes them an excellent choice for commercial fish feed production. Additionally, microbial phytase improves fish growth as these enzymes enhance nutrients bioavailability and their digestion. This review article presents the application of microbial phytases as a feed additive, and their role in enhancing fish growth.

“…S. cerevisiae was purchased from Indrasari Chemical Store, Semarang, Central Java, Indonesia. The standard fish feed was a pellet containing 35% protein, 5% fat, 6-8% fiber, 13% ash, 12% water content, and 272.56 Kcal DE/kg (Rachmawati et al, 2018). The standard feed was supplemented with S. cerevisiae in various doses, including 0 g/kg feed (A), 5 g/kg feed (B), 10 g/kg feed (C), 15 g/kg feed (D), and 20 g/kg feed (E).…”

The availability of good feeding on fish performance is needed to improve the poor aquaculture condition. The study examines the effects of Saccharomyces cerevisiae supplementation on the growth, survival rate, and blood profile of saline red tilapia in the semi-intensive culture. Sixty saline red tilapia (4.58 ± 0.09 g) were divided into five groups and received standard feed with supplementation of S. cerevisiae at different doses: (A-E) 0, 5, 10, 15, and 20 g/kg feed. S. cerevisiae was sprayed onto the feed and given to fish three times/day for 49 days. The efficiency of feed utilization (EFU), feed conversion ratio (FCR), the protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR), and blood profiles were examined. The water quality parameters were also evaluated, including temperature, pH, dissolved oxygen, NH<sub>3</sub>, and salinity. Data were analyzed using ANOVA followed by the Duncan test. The supplementation of 10 g/kg S. cerevisiae could significantly (p<0.05) increase EFU (85.13%), PER (3.76), RGR (4.53%), and survival rate (97.53%), and decrease FCR (1.42) of the saline red tilapia. All doses of S. cerevisiae significantly (p<0.05) increased the number of hematocytes (34.68, 35.96, 34.14, and 34.52%, respectively) and hemoglobin (12.98, 13.58, 12.73, and 12.67%, respectively) of fish. The highest number of erythrocytes and leucocytes was found in dose 10 g/kg feed. All water parameters were stable during the study. Therefore, S. cerevisiae can be used as a feed supplement for red tilapia fish to increase the growth, survival rate, and blood profile of the saline red tilapia.
