Fry production and its marketing system of North-West fisheries extension project at Parbatipur, Dinajpur, Bangladesh

Abstract

Abstract:In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur-a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel.

Efficacy of dry and wet carp pituitary gland (CPG) in the induced breeding of Cyprinus carpio var. specularis (Lacepède, 1803)

“…Aquaculture practices in Bangladesh started with natural seed but now it is almost entirely (99.55%) replaced by hatchery produced seed, while supply of fingerlings is considered as a prerequisite for the development of aquaculture (Al-Asif et al, 2014;Ali et al, 2018;Faruk et al, 2018;Islam et al, 2017;Webber and Riordan, 1976). Since 1975, artificial fish breeding techniques and low cost hatchery designs have been successfully adapted in Bangladesh (Islam et al, 2016(Islam et al, , 2017. Mirror carp (C. carpio var.…”

Growth and economic performance of different supplementary feed on female mud crab (Scylla olivacea) fattening in plastic box

“…Subsequently, there is a great potential of crab culture throughout the coastal area in Bangladesh. Millions of poor fishers, traders and transporters are directly or indirectly dependent on crab fishery in Bangladesh (Zafar and Ahsan, 2006;Hossain et al, 2018;Hossain et al, 2015;Asif et al, 2014;Rahaman et al, 2015;Islam et al, 2017;Leela et al, 2018;). The mud crab was first exported in 1977-78 fiscal year and become a stable business in 1982.…”

Comparative analysis of nutritional quality of different fish feed available in greater Noakhali region, Bangladesh

“…The analyzed mean moisture content of fish feed varied from 7.43% to 15.33%. Dry feeds contain 8-10% moisture while the water content of moist feed ranges from 17 to 40% or more (Lall, 1991;Zaman et al, 2017;Islam et al, 2017b;Haq et al, 2017;Rahman et al, 2018;Rahman et al, 2019;Biswas et al, 2018 andYeasmin et al, 2018). Roy (2002) reported that a diet containing 9.8% moisture appears to be more suitable for GIFT tilapia.…”
