Three different doses of PG were tested, viz. 17, 15 and 13 mg PG\/kg body weight for female and 14, 12 and 10 mg PG\/kg body weight for male with maintaining (1:1) male and female ratio. The hormone doses 13 mg\/kg for female and 10 mg\/kg for male provided the best result i.e. 91.33\u00b12.08% fertilization and 85.00\u00b12% hatching rates. Mean survival percentage of the spawns up to 21 days was 8.00\u00b11%.\u00a0 The fertilized eggs were found to be transparent, demersal, spherical, adhesive and brownish in colour and first cleavage took place within 35-40 min post-fertilization at 29.56\u00b1 0.25oC. Hatching took place at 24 h. after fertilization. Newly hatched larvae were 3-4 mm in length and slender, transparent and the yolk sac oval in shape. Anus was situated at almost mid ventrally. Larvae started to feed at 48-72 h post-hatching.<\/p>\n<p><strong>Key words: <\/strong><em>Mystus vitttus, <\/em>Induced breeding, Larvae fertilization<\/p>\n<p>[\/showhide]<\/p>\n<p><strong><a style=\"color: #800000;\" href=\"http:\/\/agroaid-bd.org\/ralf\/wp-content\/uploads\/sites\/2\/2014\/12\/2.-Milton.pdf\">Download Full Article PDF<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author:\u00a0Rabeya Yesmin, Salina Akhter Sume, Md.
