TAILIEUCHUNG - Growth performance of giant eel (anguilla marmorata) at hoa my reservoir, Thua Thien Hue province, Vietnam

Growth performance of giant eel (anguilla marmorata) at hoa my reservoir, Thua Thien Hue province, Vietnam. Fingerlings’s Gianteel was selected for this research, starting from October 5, 2010 to February, 2012 at Hoa My reservoir. This fingerlings were stocked in four floating cages with drilled holes Ø cm, suspended by plastic buoys and the fingerling stocking density were 240 head/cage and during this adaptation period, the changes of weight were recorded 1 time/ 2 months. | BÀI BÁO KHOA HỌC GROWTH PERFORMANCE OF GIANT EEL (ANGUILLA MARMORATA) AT HOA MY RESERVOIR, THUA THIEN HUE PROVINCE, VIETNAM Luong Quang Tuong1,2, Nguyen Phi Nam2 Abstract: Fingerlings’s Giant eel (Anguilla marmorata) was selected for this research with average weight ± 6,98 g/head, starting from October 5, 2010 to February, 2012 at Hoa My reservoir. This fingerlings were stocked in four floating cages with drilled holes Ø cm, with size ( x x meter each), suspended by plastic buoys and the fingerling stocking density were 240 head/cage and during this adaptation period, the changes of weight were recorded 1 time/ 2 months. Objective of this research is to find the suitable selection of using fresh trash fish or industrial feed to culture Giant eel in fresh water. As a result, the findings show that Hoa My reservoir likes potential area with stability of pH ( – ), DO (4 – 6mg /l). The temperatures fluctuating from 0C - 30 0C in the tolerance limit of this fish, do not effect on their growth performance. Giant eel using fresh trash fish reached ± g/head, gaining an income of VND (320,000 VND/kg of fish) and Giant eel with industrial feeds only ± ( VND per/kg of fish), loss of than VND. This research suggest that farmer should use the fresh trash fish to culture the giant eel. Keywords: Hoa My reservoir, Giant eel, feed, economic efficiencies. 1. INTRODUCTION1 Aquaculture has an important role in providing food security employment as the fastest growing food-production sector (Lowe et al. 2012) in local areas and on the global scale, fish provide the potential for environmental impacts (Edwards 2013) because the advantage of fish characteristic which requires less than 2 kilograms of feed for providing per kg product and it makes them the most efficiently producing aquatic animals based on feed and an amount of water use (Verdegem, Bosma, and Verreth 2006).
