Abstract/ Executive Summary:

The present study was conducted to assess the feed quality and fish health status of farmed fishes in Mithapukur and Kaunia upazila of Rangpur district of Bangladesh. The data were collected from 10 fish farms through well-structured questionnaire from the selected area from July 2013 to April 2014. The survey revealed that average pond size was 0.14 ha with a depth of 1.73 m. Indian major carps and exotic carps were mainly cultured using different aquaculture inputs like fertilizer, feed, seed, and chemicals. The average stocking density was found 13,480 fry/ha with an The Length gain (cm) and weight gain (g) of the farmed fishes varied between 14.56 to 26.67 cm and 228.34 to 634.82 (g) respectively. The specific growth rate (SGR% day) ranged between 1.51 to 2.24% and survival rate ranged between 48 to 73%. The average annual yield of 1432.00 Kg/ha. The average profit/ha from fish culture was found to be Tk. 76301.5/yr with an average benefit-cost-ratio (BCR) of 1.83. Investigation on health conditions of farmed fishes were performed through clinical observations of the fishes to find out any kind of abnormalities. Among the water quality factors, water temperature was found at unfavourable level for fish during the colder months. Clinically, it was observed that the fishes were more affected from December and January and almost normal in appearance during June, September and March. Different clinical symptoms like rough skin, scale loss, red spots and dermal lesions were noticed in December. Pathological condition of fish gradually reduced in February. The feed quality was assessed through analysis of proximate composition of some selected fish feeds. Moisture, protein, lipid, ash, crude fiber and carbohydrate content of wheat bran, rice bran, mustard oil cake and mega feed varied between 9.79% to 17.46%, 16.22% to 29.81%, 7.77% to 9.80%, 7.08% to 18.91%, 3.30% to 7.40% and 28.84%to 45.45% respectively. The present research findings suggested that quality feed would be essential for feed formulation through which increased growth and production could be achieved. The growth performance and health status of farmed fishes in Nischintopur Fish Farm was higher than Bondhu Fish Farm due to proper management practices such as proper stoking density, proper use of organic fertilizer, quality diet and regular monitoring. Fish disease, non-availability of fish fry, pouching, insufficient water in dry season, poor technical knowledge, lack of quality feed and lack of money for fish farming were identified as the major constraints. If the suggested constraints could be solved, fish production in the study area would possibly be increased tremendously.

Keywords: Feed quality, Fish health, Farmed fishes, Rangpur district

Location: Mithapukur and Kaunia upazila, Rangpur district

Start Date: 00-07-2013

End Date: 00-04-2014

Program Area: Animal Health and Management

Commodity: Fish

Objectives:

To identify the quality of artificial feed for carps.
To study the growth performance and survival rate after using artificial feed.
To evaluate the health status of the cultured farmed fishes.

Methodology:

Period of data collection: The present investigation was imposed for a period of 10 months from July, 2013 to April, 2014 to find out the feed quality and fish health status of farmed fishes of two Upazila of Rangpur district namely Mithapukur and Kaunia in Bangladesh. Selection of Study sites: Ten fish ponds, five from Mithapukur Upazila (village Nischintopur, 10 km to the southern side of Rangpur) and five from Kaunia Upazila (village Modamodon, 12 km to the northern side of Rangpur District) under two fish farms were selected for present study. Preparation of the survey schedule: According to the objectives of the study, a survey schedule was prepared to collect the expected data. Before collecting the primary data, a draft questionnaire was developed which was pre-tested with a few pond fish farmer to verify the relevance of the questions and the nature of the sample producers. In the pre-testing, much attention was given to any new information in the draft questionnaire in order to reach the objectives of the study. According to the experience gained in pre-testing, necessary adjustments were done and the final set of questionnaire was improved, rearranged and modified based on their feedback. The questionnaire covered a wide range of questions and divided into several sections. The first section focused on general farming and farmer’s information, the second section on pre-stocking pond management, the third one covered information related to fish stocking and culture strategy, the fourth one covered fish farming issues relating to sources of farm water, fry management, feeding management, waste management, Disinfection facilities and the fourth section focused on fish health and disease problems, their economic loss, management interventions used to control disease. This section was used only when the farmers reported health problems in their ponds. The final section covered about production and marketing facilities of aquaculture. Selection of sample producers: Simple random sampling method was followed for the interview. It was not possible to include all the farms under the study because of limitation of time and resources. A responsible size of sample to achieve the objectives of the study was considered. Considering these aspects 10 sample ponds of the two farms were selected randomly for the study. Collection of data: The study was based on collection of primary data. Primary data were collected with pre-tested structured questionnaires by direct interview method. With a set of interview schedule designed for this study, each respondent was given a brief introduction about the nature and purpose the study during the interview. Besides, the researchers asked the questions systematically in a very systemic manner with explanations wherever it was felt necessary and the information were recorded. At the time of interview the physical conditions of the ponds and many parts of fish cultivation methods like pond repair, application of food and fertilizers, harvesting, etc. were observed as a result there was scope to well understand the fish production technology in the study area. Time required for each interview was about 30 minutes to an hour. After collecting the data through questionnaire interview, it was necessary to check the information for justification of the collected data. If there were such items, which had been contradictory, then information was collected from key informants. Cross check interviews were conducted with key informants such as District Fisheries Officer, Upazila Fisheries Officer (UFO) and NGOs working in aquaculture. Key informants were interviewed at their office or houses. Estimation of growth, survival and production: Regular random sampling of fish was carried out at every 3 months interval by using a cast net and l0% fishes of each species from each pond were caught and health and growth were monitored and finally after harvested survival rate and production was estimated. Estimation of Economic Return (EER): Finally calculation has been made to estimate the economic return deducting the production costs per hectare, from the value of the production fish per hectare in different treatments' cost- benefit ratio was calculated. Processing and analysis of data: All the collected information was accumulated, coded and entered into a database. The collected data were scrutinized and summarized carefully before the actual tabulation. The processed data were transferred to a master sheet from which classified tables were prepared revealing the findings of the study. Then the data were tabulated into a preliminary data sheet of a computer and compared with computer spread sheets to ensure the accuracy of the data entered. After data entry, the data were analyzed with computer programs, Microsoft Excel.
