Snakehead (Channa striatus) belonging to the Channidae family is an indigenous freshwater fish of Malaysia that has carnivorous behavior. C. striatus command high prices since it has a strong demand and are sold alive. It is a commercially important species in Thailand, Philippines, Cambodia and Vietnam. Increased human activities destroyed the feeding and breeding grounds of this species, leading to decline in wild catches. C. striatus is considered as an endangered fish in Bangladesh. The research of C. striatus provides an account of current knowledge, especially on reproduction, culture and nutritional requirement of snakehead. The problems encountered in snakehead culture are discussed and suggestions made to overcome the problems are highlighted. |

The purpose of the study was to investigate the effect of broodfish sex ratio on seed production of red tilapia, Oreochromis sp. using hapa nets suspended in an earthen pond. Sex ratios used in the experiment were 1:1 and 1:3 (male: female) with three replicates per treatment. Eight broodfish were placed in the hapa, each with a combination of either 4 male: 4 female or 2 male: 6 female to maintain the treatment sex ratios. Tilapia seeds (free swimming fry, sac-fry and eggs) were harvested every 21-day post-stocking. The broodfish were fed 3% of their body weight with a diet that contained 28% crude protein and 4% crude fat. Seed production of both sex ratio treatments were analyzed using the t-test. There were no significant differences (p>0.05) in seed production and female broodfish performance between the two sex ratios tested. |

Twenty-five days feeding trial was conducted to evaluate the growth and survival
of Channa striatus fry fed with three types of fresh foods (bloodworm,
trash fish and Acetes shrimps). Ten fry were stocked in each aquarium
(46x46x37 cm) and fed ad libitum twice a day (1000 and 1700 h). All treatments
were triplicate. The fry fed trash fish showed a significantly (p<0.05) higher
weight gain percentage (376.50±20.74%) than those fed with Acetes
shrimp (233.05±10.18%) and bloodworm (199.08±17.25%). The final
mean total lengths of fry fed with trash fish, bloodworm and Acetes shrimps
were 7.91±0.23, 7.28±0.23 and 7.21±0.17 cm, respectively.
Fry fed with trash fish also showed the best Specific Growth Rate (SGR) value
(6.24±0.17% day-1) followed by Acetes shrimp (4.81±0.12%
day-1) and bloodworm (4.33±0.22% day-1). The best
Food Conversion Ratio (FCR) value (3.63±0.27) was found among fish fed
with trash fish compared to those fed Acetes shrimp (7.41±0.88)
and bloodworm (11.48±1.51). It could be concluded that trash fish was
an excellent feed for C. striatus fry in term of growth, weight gain
and FCR. |
