Abstract

Tinfoil barb, Barbonymus schwanenfeldii (Bleeker, 1854), is a potential freshwater fish for Indonesian aquaculture. Before widely used, the candidate needs to be evaluated. This research aimed to evaluate the reproductive performance of the first generation (G1) and larval performance of the second generation (G2) of domesticated tinfoil barb. A total of 68 female and 24 male broodstocks were selected for the artificial breeding program. The gonadal maturity test was carried out by canulating the eggs every month. Before spawning, GnRHa hormone was injected into the dorsal area (0.5 mL/kg for female and 0.2 mL/kg for male). Fecundity, fertility rate, hatching rate, embryogenesis, and larvae ontogeny were recorded. The results showed that the first matured G1 males of tinfoil barb were at the standard length of 16.01 ± 1.18 cm, while females at 15.79 ± 1.23 cm. The mature broodstock indicated by the gonad maturity stage III and IV confirming higher estradiol concentration (above 400 pg mL-1). The fecundity of two mature broodstock-sized of 217.2 g and 197.3 g were 12,495 and 15,782 eggs, respectively. The spawning season of G1 tinfoil barb was in October and November (rainy seasons). The fertilized eggs latency time was 10 hours 44 minutes at 25°C and hatched after 23 hours 7 minutes. The fertility rate was 96.96 % and the hatching rate was 95.16 %. The survival rate of G2 normal larvae was 100 % at three days of the rearing period. The G2 larvae production in this experiment provides an excellent opportunity for fish diversification both for aquaculture and restocking.

Abstract

Tingkat kelangsungan hidup yang sangat rendah pada larva merupakan faktor pembatas dalam produksi benih ikan tuna sirip kuning. Larva mengalami kematian massal pada hari ke sepuluh hingga juvenil, dengan nilai kelangsungan hidup kurang dari 0,05%. Faktor utama penyebab kematian larva ikan tuna adalah lingkaran arus air dalam bak pemeliharaan yang mengakibatkan terjadinya kematian karna tegangan permukaan dan larva yang tenggelam. Maksud dari penelitian ini yaitu untuk mengetahui apakah larva yellow fin tuna yang dipelihara dengan beberapa desain aerasi di dalam bak pemeliharaan memiliki dampak terhadap kelangsungan hidup larva. Penelitian dirancang menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan tiga ulangan: empat batu aerasi ditengah bak sebagai kontrol A, empat batu aerasi di bawah B dan gabungan dua batu aerasi di tengah dan dua batu aerasi di bagian bawah C. Pemeliharaan dengan desain aerasi pada bagian bawah dan gabungan memberikan pengaruh nyata pada kelangsungan hidup larva yellow fin tuna dengan sintasan 0,31±0,04% dan 0,30±0,06%.

Abstract

The recirculation system in the maintenance of tortoise will affect several water quality parameters, also known as water quality dynamics. Water quality such as temperature, DO, pH, turbidity, nitrate, nitrite, alkalinity, total hardness, TAN are parameters that are directly related to the physiological system of fish. The purpose of this study was to see the effect of various recirculation systems on water quality dynamics. This study used an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications and fish were kept for 20 days. The results obtained during the research include physical and chemical parameters. The temperature was between 24.5Co-27.6Co, the highest temperature measured in the current recirculation system treatment, the degree of acidity (pH) the average pH value ranged from 6.10-7.42. The value of nitrite ranged from 0.041-0.083 mg/L. Nitrate values ranged on average from 4.40 to 5.32. The average alkalinity value ranges from 44.02 to 77.30 alkalinity has a large effect on pH. Ammonia is produced from the excretory activity of fish, the average value of ammonia is 0.05 - 0.2 mg/L. In this study, the highest survival rate was found in the current recirculation treatment with a survival rate of 99%, and the lowest survival value was found in the non-recirculating treatment with a value of 53.5%. In this study, water quality is very influential on the survival of the jungle fish.Keywords: water quality; jurung fish; maintenance; recirculation; Dynamics system
