Abstract

The research was conducted from March to May 2009, in the Laboratory ofAquaculture Technology of Fisheries and Marine Science Faculty, RiauUniversity. The aim of research was to investigate frequency of fish mealdistribution on growth and survival rate of Ompok hypophthalmus.In this research, 3 treatments with 4 replications was applied. Fish used inthis research were 4 to 4,5 cm in length. Stocking density of fish was 15fish/aquaria. Fish meal frequency applied was 3, 4 and 5 times/day. Fish diet usedin the research was commersial pellet with given doses of 10 % from fish bodyweight. Based on Anova analysis, results showed that the fish meal distribution of5 times/day gave the best result on growth of 13,42 g, fish diet efficiency 35,90 %and survival rate of 100 %.

Abstract

ABSTRACTThe research was conducted from 18 March until 16 May 2011 in Research Station of Fisheries and Marine Science Riau University. The objective of the research was to find out the suitable fish meal as long as domestication activities on the growth and survival rates of Thynnichthys thynnoides Blkr. The fish meal used in this research was shrimp pellet, snail meat, chicken intestines and vegetables. Fish were reared in the 0.5 m x 0.5 m x 0.5 cages for 60 days with stocking density of 25 fish/m3 cage. The method used in this research was completed randomized design method with four treatments and three replications. Results showed that the best absolute growth rate of 19.02 grams, daily growth rates of 2.304 % were obtained in the treatment of dried pellet combining with vegetables, while the worst performance was obtained in treatment of dried pellet combining with vegetables with growth rate of 12.39 grams and daily growth rate of 2.134 % respectively. Water quality parameters recorded in the research were water temperature, pH, dissolved oxygen and NH3 of 27 – 30 oC; 6 – 7; 4 – 4.6 ppm; 0.006 – 0.024 ppm respectively.Keywords : Domestication, Thynnichthys thynnoides Blkr, Fish meal.

Abstract

This research was conducted on April until June 2015, at Hatchery and Breeding Laboratory of Fisheries and Marine Science Faculty, University of Riau. The aim of the research was to determine the effect of ovaprim with different doses on sperm quality of signal barb (L. festivus, Heckel 1843) and for completion of this research then the best dosage obtained through observations on sperm quality will then be injected against gonads mature male brood and then spawned with the female injected with the best dose (0.7 ml/kg body weight). The results showed that ovaprim on doses 0.7 ml/kg body weight gives the best results for the cement volume (0,013 ml/g), concentration (878 x 107), motility (79,46%), viability (84,07 %). results for spawning resulted in average: fertility rate (40,39 %), hatching rate (14,85 %), and survival rate within 5 days (38,07 %).

Abstract

Information about stocking densities that are ideal for the cultivation of shellfish blood is still very limited. The aim of the study was to determine the stocking density in the rearing of blood clams. The benefits of this research was to provide information about the best stocking density for the growth of the blood clam and can be used as reference in the cultivation and further research. This study was conducted over 60 days from March to May 2013, in the village of Commander King, District Concong Affairs, Indragiri Hilir District, Riau Province. The method used was an experimental method with a completely randomized design (RAL) with three levels of the factor treatment. Treatment 1 (stocking density of 50 animals), treatment 2 (stocking density of 100 fish), Treatment 3 (stocking density of 150 fish) . Each treatment had 3 replication. Extensive research with size of each treatment area size was 50 x 50 cm (2500 cm2) fenced round with polyethylene net size of 0,5 inches. Seeds obtained from the blood clam catches directly in nature by local fishermen. Seeds stocked with as many as 900 tail with 2,33 cm and in length an average weight of 2,72 grams. The result showed that the growth length of the shellfish blood was 3,21 cm and the growth rates of 5,18 grams.Keywords: Shellfish blood, stocking density, seed, growth
