Abstract

ABSTRACT Snakehead fish (Channa striata) is a freshwater fish commodities that have high economic value, while their needs depend on natural catching. In general, hormonal induction commonly used for the efficiency of female parent utilization and enhancement quality and quantity of fish fry. One of the hormones that can be used is pregnant mare serum gonadotropin (PMSG) and antidopamine with trademark Oodev®. These hormones contain many elements follicle stimulating hormone (FSH) which can trigger the early stages of gonad maturity. The purpose of this research was to determine the effectiveness of hormone PMSG on gonadosomatic index (GSI) and hepatosomatic index (HSI). The size of female fish was 30−40 cm, weighing of 500−700 g, adapted in the aquarium and then induced with different doses of PMSG, namely: treatment A dose: 0.75 mL/kg; B: 1.0 mL/kg; C: 1.25 mL/kg; D: 1.5 mL/kg and be repeated three times. Fishes were then reared up to 72 hours to determine the development of GSI and HSI. The results showed that the best treatment was at dose of 1.25 mL/kg with GSI and HSI values of 1.37% and 3.35%, respectively. Keywords: PMSG, GSI, HSI, snakehead fish  ABSTRAK Ikan gabus (Channa striata) merupakan salah satu komoditas air tawar yang mempunyai nilai ekonomi tinggi. Saat ini pemenuhan kebutuhan hanya bergantung pada hasil penangkapan dari alam. Pada umumnya cara pemijahan buatan dengan induksi hormon dilakukan untuk efisiensi penggunaan induk serta peningkatan kualitas dan kuantitas benih ikan. Salah satu hormon yang dapat digunakan adalah pregnant mare serum gonadotropin (PMSG) dan antidopamin dengan merk dagang Oodev®. Hormon-hormon tersebut banyak mengandung unsur follicle stimulating hormon (FSH) yang dapat memicu kematangan gonad tahap awal. Tujuan dari penelitian ini adalah untuk menguji efektivitas hormon PMSG terhadap nilai indeks gonadosomatik (IGS) dan indeks hepatosomatik (IHS). Induk ikan gabus yang digunakan berukuran 30−40 cm dengan bobot 500–700 g, diaklimatisasikan di akuarium kemudian diinduksi hormon PMSG dengan perlakuan dosis A: 0,75 mL/kg; B: 1,0 mL/kg; C: 1,25 mL/kg; D: 1,5 mL/kg dan dilakukan pengulangan sebanyak tiga kali. Selanjutnya ditunggu hingga 72 jam untuk mengevaluasi perkembangan IGS dan IHS nya. Hasil penelitian menunjukkan bahwa perlakuan terbaik adalah dosis 1,25 ml/kg dengan nilai rata-rata IHS 1,37% dan IGS 3,35%, Kata kunci: PMSG, IGS, IHS, ikan gabus

Abstract

Channa marulioides is one of the species that is facing a population decrease due to high fishing activity. This study aims to determine the value of the length-weight relationship and condition factors of C. marulioides in the Kapuas River as a relevant conservation effort. Several sampling areas in this study were used to represent the Kapuas River, including Kapuas Hulu River in Kapuas Hulu Regency, Putussibau District; The central part of the waters area of "‹"‹Sintang Regency in Sintang Regency; and in the downstream waters of Pontianak City. The study carried out the sampling by analyzing the criteria for specimens with a dimension weight > 500 grams and length > 30 cm, with the same amount for each sex. The results showed that the growth type in the upper and middle waters was positive allometric with a value of b 3.1; however, it is negative allometric in the middle and upstream waters with b values "‹"‹of 2.5 and 1.7. After research, the condition factor of the upstream and middle waters was observed to be in good condition with a value of 1. However, in the downstream waters the condition of the fish was rather bad with a value below 1, namely 0.99. The study concludes there is a decrease in the quality of the aquatic environment and the food availability from the middle waters to the downstream. This is what underlines conservation efforts in the form of domestication activities within the scope of structured fish farming.
