Abstract/ Executive Summary:

A study was carried out on the quality assessment of fish feed used in different shing (Heteropneustes fossilis) farms of Muktagacha Upazila in Mymensingh District. A total of 10 shing feeds viz. as C.P, Nourish, Arab, Quality Feed, New Hope, Paragon, Chamok, Mega, Cherish and a Farm made feed were collected at monthly interval during February to April 2014. The samples were analyzed for proximate composition in the Fish Nutrition Laboratory, Department of Aquaculture, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh. Growth data were collected from farms record book and analyzed later on. The moisture content of feeds varied from 13.96 to 10.57%. Lipid content varied from 10.38 to 2.69%. The highest 33.60% protein was observed in Quality feed and the lowest (25.9%) observed in Arab feed. The highest ash (14.09%) was observed in farm made feed and the lowest ash (8.50%) observed in New Hope feed. Crude fibre content ranged between 6.60 to 4.20%. The carbohydrate varied from 40.45 to 24.84%. The maximum final weight 68.96g was observed in C.P feed while the lowest 21.05g for Arab feed. The highest weight gain (63.63g) exhibited by C.P feed whereas the lowest (19.11g) for Arab feed. The highest SGR (70.43%) exhibited by C.P feed and lowest SGR (20.55%) exhibited by Cherish feed. The maximum Production 57.99kg/dec./90 days exhibited by Chamok feed while the lowest 26.25kg/dec./90 days exhibited by Arab feed. The best FCR observed was 2.97 by feeding C.P feed and the lowest FCR observed in 4.12 by feeding Mega feed. Survival rate was varied from 96.39 to 78.36%. The maximum Benefit Cost Ratio (BCR) 2.81 and the minimum 0.89 was found with Abu Suffian Khan farm and Sabuj farm respectively. The results of the present work will be very much helpful to fish farmers for feed selection and bargain with the feed traders to select suitable feed for their fish to ensure profitable aquaculture operation.

Location: Basati and Kheruajani Union of Muktagacha Upazila of Mymensingh district.

Start Date: 00-02-2014

End Date: 00-04-2014

Program Area: Quality and Nutrition

Commodity: Feed, Fish

Objectives:

The study was undertaken to determine the proximate composition of aqua feed used by selected farmers at different shing farms of Muktagacha Upazila in Mymensingh district and to assess the growth performance of the shing, FCR and economic return by feeding different feeds.

Methodology:

Study area: Many shing fish farms have been constructed in the Muktagacha Upazila with in last decade. Therefore the study was conducted at Basati and Kheruajani Union of Muktagacha Upazila of Mymensingh district. Collection of feed samples Quality assessment of commercial and farm made feed used in different shing farms was conducted for the period of three months from February to April, 2014 to determine the nutrient availability in the feed to have sustainable fish production. Feed samples were collected from 10 catfish farms owned by Abu Sufian Khan, Kamarujjaman, Shahin Talukdar, Rabi, Abul Miah, Salim Hossain, Abu Hanif, Saddam Ali, Sabuj, Munjurul Islam Khan. The farm owners used C.P, Nourish, Arab, Quality Feeds, New Hope, Paragon, Chamok, Mega, Cherish, and a Farm made feeds respectively. Collected samples were kept in a refrigerator in the laboratory, then the samples were analyzed for proximate composition on a later date. Before starting the experiment farmers were motivated to keep a registrar, recording all about farm activities like growth performance data of fish and economic input-output data. The growth performance data as well as input-output data were collected from the farm’s record book.

Sample preparation and analysis The samples were taken from the refrigerator and kept to the room temperature for few hours. Then the required amount of samples was finely ground by a small mortar and kept it airtight container for subsequent chemical analysis. The analysis of feed was carried out in the Fish Nutrition Laboratory of the Department of Aquaculture in the Faculty of Fisheries, Bangladesh Agricultural University (BAU). The proximate composition of different fish feeds were analyzed in duplicate according to the standard procedure given in Association of Official Analytical Chemists (AOAC, 2000). Growth parameters and economic analysis Every month interval, growth in weight (g) was measured. The weight gain (g), specific growth rate (SGR % day), feed conversion ratio and production (Kg/dec/90days) was measured to evaluate the growth of fish. Feed conversion ratio (FCR), Survival rate, Production/ yield and economic analysis including fixed cost, operating cost, total cost, revenue income and net profit were calculated and evaluated.

Achievement/Findings:

Sometimes farmers use low quality feed of some feed companies or they use their own made feed of unknown quality, result in low growth and production of fishes. The research work is very helpful for determining the quality of feed that farmer use (both commercial and farm made), the findings will certainly help farmers to adjust formulation of feed towards balanced diet for getting more quality production also getting acceptable profit margin.
