Abstract

The Ramirezi (Mikrogeophagus ramirezi) is an ornamental fish in high demand with significant economic value. The high demand for this commodity has yet to be met by the quantity of fry production generated by farmers. It is due to the Ramirezi's long maturation time and slow growth, which are influenced by factors such as the feed used. This study aimed to evaluate the effect of feeding with different feed types on the growth and development of the gonads of prospective Ramirezi broodstocks. The research design employed a completely randomized design (RAL) with four treatments and three replications, using a combined ratio of artificial feed to bloodworm (Chironomus sp.): (A) 3:0, (B) 0:3, (C) 2:1, and (D) 1:2, for 45 days of culture. The results showed that a combination of artificial feed and bloodworm in a 1:2 ratio increased the absolute body growth of Ramirezi by 1.267 g, with a positive allometric growth pattern. This ratio also affected the egg diameter, leading to a higher percentage of broodstock maturing more quickly and improving reproductive performance, as seen in the parameters of the number of eggs produced (ranging from 80-200 eggs), a 96.83% fertilization rate, and a 91.80% hatching rate. Therefore, researchers and farmers can combine artificial feed and bloodworms in a 1:2 ratio in Ramirezi cultivation activities.Ramirezi (Mikrogeophagus ramirezi) adalah salah satu ikan hias yang banyak diminati dengan nilai ekonomis tinggi. Tingginya permintaan terhadap komoditas ini belum diimbangi dengan jumlah produksi benih yang dihasilkan oleh pembudidaya. Hal tersebut karena secara biologis ramirezi memiliki waktu maturasi yang cukup lama dan pertumbuhan yang lambat. Salah satu factor, yang dipengaruhi oleh beberapa faktor seperti pakan yang digunakan. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian pakan dengan jenis pakan berbeda terhadap pertumbuhan dan perkembangan gonad calon induk ramirezi. Rancangan penelitian yang digunakan yaitu rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga ulangan, menggunakan rasio kombinasi pakan buatan dengan cacing sutra (Chironomus sp.): (A) 3:0, (B) 0:3, (C) 2:1, dan (D) 1:2, selama 45 hari pemeliharaan. Hasil penelitian menunjukkan bahwa pemberian kombinasi pakan buatan dan cacing sutra dengan rasio 1:2 mampu meningkatkan pertumbuhan bobot mutlak ramirezi sebesar 1,267 g, dengan pola pertumbuhan alometrik positif. Rasio ini memberikan pengaruh terhadap diameter telur, menghasilkan persentase induk yang lebih cepat matang gonad serta meningkatkan performa reproduksi, terlihat dari parameter jumlah telur yang dihasilkan (berkisar 80-200 butir), derajat pembuahan 96,83%, dan derajat penetasan sebesar 91,80%. Oleh karena itu, peneliti dan pembudidaya dapat mengombinasikan pakan buatan dan cacing sutra dengan rasio 1:2 pada kegiatan budidaya ramirezi.

Abstract

One way to increase the production of Nile tilapia (Oreochromis niloticus) is to breed dominant male monosex tilapia. Applying natural steroid hormones derived from plants such as Tribulus (Tribulus terrestris) is safe and environmentally friendly. This plant includes flavonoid compounds, steroid saponins, and aphrodisiacs. This study aims to evaluate the effect of Tribulus seed extract on early gonadal differentiation, sex ratio, and growth performance of tilapia juveniles. The study was conducted for 60 days at the Technical Implementation Unit of Freshwater Aquaculture Fisheries Service (UPTD PBAT) in the West Region of Kota Agung, Tanggamus. The study design used was a Completely Randomized Design (CRD) with 5 treatments: 17α-methyltestosterone 0.0005 g/L (P1), and different doses of Tribulus extract 0 g/L (P2); 0.005 g/L (P3), 0.01 g/L (P4), 0.02 g/L (P5) with three replications each. Ten-day-old larvae were immersed in the treatment solutions for 12 hours weekly, repeated three times, and water quality was monitored during the first month to ensure optimal conditions.  The larvae were initially fed Artemia four times per day for up to 20 days and then switched to a commercial diet until the end of the rearing period. Histological analysis of gonad sex differentiation was performed at different stages and sampled 10-60 days after hatching to determine the sex ratio of each treatment group. The results showed that the treatment significantly affected the early gonad development and sex ratio (P<0.05), while it did not significantly affect the growth performance and survival rate of tilapia juveniles (P>0.05). The best dose to increase the percentage of males in Nile tilapia was the treatment with Tribulus seed extract at 0.01 g/L.
