Abstract

The thyroxin hormone plays an important role in the process of metabolism, yolk sac absorbsion, and growth of fish. The aims of this research were to observe the effect of various concentration of thyroxin (T4) on the absolute growth weight, total length, survival rate, and pigment development of pink zebra fish larvae (Brachydanio reiro ) after being reared 42 days. The pink zebra fish larvae at 4 day age with the average weight of  0,002 – 0,003g and average length of ± 3.10 – 3.43 mm were immersed at various concentration of T4 for 24 hours. Prior the treatment fish larvae were dipped into 1 ppt salinity for 2 minutes then transferred into 1 Liter, 1ppt saline and various T4 in plastic bags. The thyroxin concentrations were A (0 mg / L); B (0.05 mg / L); C (0.10 mg / L) and D (0.15 mg / L) respectively. The stocking density was 40 fish/L. After that they were transferred into aquariums and reared for 42 days. Completely Randomized Design (RAL) with four treatments and three replications were used. The variables observed were absolute and specific growth, total length, survival rate and hue degree. The results showed that the thyroxin hormone had significant effect on absolute growth weight, total length and specific growth rate.  The dosage 0.1 mg/L was the best treatment on absolute growth, total length, and specific growth rate. Whilee the survival rate showed no significant differences across the treatments. Treatment C also demonstrated the best ppigment development (14.60 + 0.36º hue) compared to others.

Abstract

Anesthesia of fish with citronella oil in a closed transportation system has never been tested on prospective tilapia broodstock. The broodstocks transportation activities are to ensure survival and keep the reproductive stages undisturbed and safe to the destination. This study aims to determine the effect and the best dose on anesthesia with citronella oil for prospective tilapia broodstock in closed transportation systems. The research was conducted on 27 April – 4 May 2021 at Fish Seed Hall Potrobangsan, Magelang. The test material used citronella oil with a fish density of 10 fish/6 liters per bag. The experimental design used was a completely randomized design with five treatments and three replications with doses of citronella oil, namely A (0 mL/L as control); B (0,05 mL/L), C (0,10 mL/L); D (0,15 mL/L); and E (0,20 mL/L). Fish were transported for 13 hours with artificial simulation. Parameters observed were fish behavior during anesthesia, time to faint and recover, survival, water quality, blood glucose, blood profile (erythrocytes, leukocytes and hemoglobin), Hepatosomatic Index and Gonadosomatic Index. Behavior during anesthesia showed that the operculum slowed down, response weakened and swimming balance was lost. Different dose of citronella oil had a significant effect on survival, blood glucose, erythrocytes, and leukocytes, but had no significant effect on hemoglobin, Hepatosomatic Index (HSI) and Gonadosomatic Index (GSI). The best dose of citronella oil was 0.10 mL/L with an average survival of 93.33%.Keywords: anesthesia, citronella, tilapia, broodstock, transportation
