Abstract

The kissing gourami (Helostoma temminckii) is a freshwater species increasingly cultivated in controlled aquaculture systems. However, its production is hindered by the limited availability of broodstock and fry, which still heavily depend on natural catches that fluctuate seasonally. To address this challenge, controlled environment aquaculture offers a sustainable solution to boost the kissing gourami population. One effective method is semi-natural spawning through gonadotropin hormone induction using Ovaprim®, which promotes year-round reproductive readiness in broodstock. This study aims to apply and evaluate the semi-natural spawning technique of kissing gourami using Ovaprim® at UPR Doa Mandeh, Ogan Ilir. Conducted between August and September 2024, the research compared two treatments: natural spawning (P0) and semi-natural spawning (P1). The findings demonstrated promising results, with a fecundity of 9,619 eggs, a fertilization rate of 90.4%, a hatching rate of 94%, and a survival rate of 95%. Water quality parameters remained within optimal ranges, with broodstock pond temperatures between 30–30.6°C and pH levels of 7.27–7.53, while the rearing aquarium maintained a temperature of 31°C and a pH of 7.62–7.66. These results highlight the potential of semi-natural spawning using Ovaprim® as a viable approach for enhancing kissing gourami reproduction, reducing dependency on wild populations, and supporting sustainable aquaculture practices.

Abstract

Applying probiotics to the recirculation system can support successful catfish production. This study aims to apply an aquaponic cultivation method that combines catfish (Clarias sp.) and water spinach cultivation by adding Probio-7 probiotics as a digestive aid to accelerate growth and improve the survival rate of catfish. This study was carried out at UPR Doa Mandeh, using the experimental design that compared the effects of probiotic application on aquaculture performance, and aimed to evaluate the effectiveness of weekly probiotics administration in a controlled aquaculture setting. Probiotics are introduced at the start of the maintenance period and reapplied weekly, following a 30% water loss, and promptly replaced with clean water. This routine was designed to maintain optimal water quality and microbial balance, supporting healthier aquatic life. The consistent probiotic treatment, aligned with systematic water management, highlights a practical approach to improving fish health and growth performance in sustainable aquaculture practices. The treatments used were without probiotics (P0) and the addition of probiotics at a rate of 0.25 mL L- 1 water (P1). The results of the research activities in P1 showed absolute length growth of 16.71 cm, absolute weight of 16.44 g, feed efficiency of 84.3%, and fish survival rate of 79%. These values were higher than those in P0, which had an absolute length growth of 5 cm, absolute weight of 11.94 g, feed efficiency of 84.3%, and fish survival rate of 77%. Water quality during the study remained within the optimal range, supporting the growth and survival of catfish.

Abstract

Ikan lais (Kryptopterus palembangensis) merupakan salah satu ikan endemik yang ada di Sumatera Selatan. Ketersediaan ikan lais di alam mulai menurun karena penangkapan yang dilakukan oleh masyarakat secara terus menerus akan mengganggu kelestarian ikan lais. Diketahui nilai ekonomis yang tinggi menjadi penyebabnya. Oleh karena itu perlu dilakukan upaya untuk pengembangan budidaya ikan lais agar dapat diproduksi secara terkontrol. Metode penulisan yang digunakan yaitu studi pustaka. Adapun teknologi dan manajemen dari ikan lais diantaranya perbedaan padat tebar pada keramba jaring apung, pemberian jenis pakan berbeda, perendaman larva pada larutan probiotik, pengaruh perbedaan suhu dan pematangan gonad dengan mineral Fe. Kemudian untuk rata-rata kualitas air dalam pertumbuhan ikan lais adalah suhu 25,20-32,00 ºC, kisaran pH sebesar 4,70-7,90, DO 2,60-8,00 mg L-1 dan kandungan amonia berkisar 0,010-2,000 mg L-1. Ikan lais termasuk dalam kelompok ikan karnivora karena jenis makanan utamanya adalah ikan kecil, insekta dan udang. Pada ikan yang diteliti secara terkontrol, pakan menggunakan Tubifex sp. memberikan pertumbuhan dan kelangsungan hidup yang tertinggi. Pemijahan ikan lais baji satu kali dalam setahun dengan pola pemijahan total spawner di musim penghujan yang dimana pada saat permukan air mulai naik dan pemijahan dilakukan di dalam celah-celah bebatuan. Gambaran sel darah merupakan aspek pendukung dalam menentukan status kesehatan ikan. Kondisi fisiologis ikan yang sehat ditandai dengan adanya pertumbuhan yang meningkat. Fisiologis pertumbuhan ikan lais dalam keadaan sehat yaitu, total eritrosit 264,00 ± 3,00 x104 sel mm-3, hemoglobin 8,3±0,11 g/dL, hematokrit 26,66±0,57 %, total leukosit 2,53±0,01 x 104 sel mm-3 dan Glukosa darah 89,00 ± 1,00 mg/dL
