Abstract/ Executive Summary:

Preliminary success on local pangus seed production showed gonadal development determined by observing secondary sex characters and carp pituitary gland extract (cPGE) was used as inducing agent. A total of 6 pairs of spawners were injected and ovulation occurred successfully. Fertilized eggs did not hatch out after 24 hours. Indiscriminate killing of immature pangas from the Meghna and other river is a burning issue now a day. Therefore a study was conducted to asses the impact of indiscriminate killing of pangus seed. Data was collected through In Situ observation in 15 days interval on the much availability of pangas fry/fingerlings and indiscriminate killing of pangas by different gear from some pre-selected points of upper and lower Meghna river Viz.

Program Area: Variety and Species

Commodity: Pangus

Objectives:

Optimization of induced breeding techniques of P. pangasius; study of indiscriminate killing of pangus seed in riverine habitat.

Methodology:

Mass seed production of threatened fish pangus, P. pangasius was included brood selection in mid June-August, induced spawning with selected brood, observation on ovulation, fertilization rate, hatching rate and spawn survival rate. Fingerlings were stocked @ 5-15/dec. and commercial Mega feed (pallet) was supplied @ 4-6% of body weight.
