livelihoods through collection and marketing of the The respondents were divided into groups on the
aqua-products. In view of this, an attempt was
made to evaluate the importance of various aqua-
products that come in the Khulna city markets. A
questionnaire survey was made on 50 selling
men/women of 8 different markets about the type
of plants and fishes collected, their season of
availability, volume of harvest, selling price and
the marketing channel of the products. A total of
10 different types of aquatic vegetables and 12 SIS
of fish were seen to be harvested and sold in the
markets of the metropolis. According to the seller,
most of the vegetables are available throughout the
year; however, the survey revealed that the peak
season was during August-December. Depending
upon the collection and demand in the market, on
an average, up to 12 Kg vegetable and 2 Kg fish
were sold daily. The supply of the peri-urban aqua- were decreased in post shrimp culture compared to
products to the urban markets was highly informal.
This production venture could be organized and
upgraded through motivation, training and credit
support to the collectors to make meaningful

landless (00.49 acre), marginal (0.5-1.0 acre),
small (1.01-2.49 acre), medium (2.5-7.49 acre) and
large (>7.5 acre). Collected data were compiled,
tabulated and analyzed by quantitative test. From
the result it was found that mean yield of rice, rice
