Abstract/ Executive Summary:

The present study was conducted in three seasonal beels in Gacha union under Gazipur sadar upazila in Gazipur district during the period from June 2015 to January 2016. The objectives of the study were to evaluate the impact of stocking common carp on the abundance and biodiversity of native fish species in seasonal beels. Three seasonal beels such as Baroholai, Makhna and Buridha which were connected with Turag River through different canals were selected to implement the study. Baroholai and Makhna beel were stocked with common carp fingerlings at 2500 per hectare. Buridha beel served as control. Necessary data were collected from the fishermen and lease holders of the concern beel through using structured questionnaire by survey method. A total of 42-43 species of fishes were recorded from stocked beel as against of 43 species in control beel. Shanon- Weiner diversity index averaged 2.58 in stocked beel as opposed to 2.68 for control beel. The studied beel had medium richness in terms of biodiversity and faunal abundances. Per hectare fish production was 522-577kg in stocked beels as compared to 365kg in control beel. Cyprinidae was the most abundant group contributing to the bulk of fishery yield. Surface feeder took a lead over other groups of fishes in stocked beel as opposed to bottom feeder in case of control beel. Bottom dwelling small catfishes seems to be affected in presence of common carp in the stocked beels. Control beel harboured increased number and quantity of catfishes. Fish productions in the seasonal beels were profitable. Per hectare total cost of fish production averaged tk 34976.67 as against of total gross return of tk 92683.67. Benefit cost ratio (BCR) was found to be 2.57-3.42 in stocked beel and 2.01 in control beel. Further researches are needed to precisely determine the possible consequences of stocking common carp in seasonal beels.

Commodity: Carp fish

Objectives:

The present research work has been undertaken to determine the yield performance of Common carp in this selected beels; to determine the effect of Common carp on Biodiversity of native species in the beels; and to assess the economic contribution of Common carp stocked in the beels.

Methodology:

Study period The present study was conducted during the period from May 2015 to January 2016. But data was collected from October to January in the studied beels. Study area The present study was conducted in three beels in Gacha union under Gazipur upazila in Gazipur district. Barohalai with coordinate, 23°56'08.5"N 90°21'57.8"E; Makhna with coordinate 23°56'30.7"N 90°21'56.8"E and Buridha with coordinate 23°56'15.9"N 90°22'11.6"E. Sampling procedure Data were collected twice in a month in order to determination of catch composition, amount of fish harvested and species assemblage in three beels. Grouping of indigenous species Indigenous fish species recorded during the period of investigation were arranged according to arbitrarily family guild, niche based tropho-tropic guild and tropho-spatial guild for the sake of result interpretation. Niche-based tropho-trophic fish guilds Niche-based tropho-trophic fish were grouped as, Planktivore, Detritivore, Omnivores, Predators, Larvivore, and Ovolarvivores. Niche based tropho-spatial fish guilds Niche based tropho-spatial fish guilds were grouped as, Surface feeder, column feeder and Bottom feeder. Species assemblage impact assessment Estimation of Shanon-Weiner Diversity Index The Shannon’s diversity index (H?) was used to measure the extent of diversity by combining aspects of species richness (S) and evenness (E). The formula for Shannon diversity index is: H = - pi Ln Pi Pi = proportional abundance of the I th species = ni /N ni = number of individual recorded in I th species N = total no. of individuals in the sample Ln = natural log. Species evenness (E) = H/Hmax Hmax = Log(S) S = Species richness Inferences can be drawn on the basis of the H? values calculated. The lesser values will be the lower diversity and vice-versa. Fish catch estimation Total catch of fish during sampling was calculated as follows: Total catch for a specific type of gear = N - f- CPUE N = No. of fishing days per year f = Mean number of individual fishing unit per day CPUE = Mean catch per unit effort Total catch for gears = Sum of catch by different gears Total catch from the ditches = average catch from a ditch × total no. of ditch. Total catch = total catch from all gears + total catch from all ditches. Data analysis The data were scrutinized and checked for possible inconsistencies. After thorough verification, the data were compiled in tabular form and entered into MS Excel sheet for performing necessary analysis. Statistical functions such as, range, mean, standard deviation and percentage were used to explain the data. Student’s t-test at 5% level of significance was employed to compare the treatment (common carp stocking) means with that of the control.

Achievement/Findings:

Stoking of common carp in seasonal beels appeared to be economically profitable in the context of Bangladesh. Though common carp exerts a little bit negative effect on the bottom dwelling fishes but its addition to the seasonal beels seems to be beneficial in terms of increased fish production and profit. Further studies should be conducted to precisely determine the consequences of stocking common carp in open water system.
