Abstract/ Executive Summary:

This study was performed in Fulpur upazila under Mymensingh district for the period of 13 months from August 2010 to August 2011 to know the socio-economic and aquaculture status of fish farm owners and to assess the nutritive value of commercial fish feed available at Fulpur upazila of Mymensingh district. Fish farm owners were prominent in the study area and majority was illiterate but had the ability of signature. The monoculture and polyculture farm in the studied area were established in ranged from 1995 to 2005, respectively. Most of the fish farm owners followed polyculture system and had small farm area. Majority of fish farm owners leased water body for aquaculture. The minimum size of the farm was 0.162 ha and maximum size of the farm was 3.722 ha. The average depth of the water body in winter season was 1.61 meter and in summer season was 2.32 meter. Majority of fish farm owners followed proper pre-stocking and post stocking management with maintaining high stocking density of fish and using either commercial or farm made fish feed. Among the commercial fish feed tested the highest value of moisture was found in Aftab feed, protein in Nourish feed, lipid in CP feed, ash in Aftab feed, fiber in ACI feed and carbohydrate in ACI feed. Most of the commercial fish feed maintain standard level of chemical composition.

Objectives:

A questionnaire survey to observe the quality of fish feed at Fulpur area

Methodology:

Study area: This experiment was performed in Fulpur upazila under Mymensingh district. Duration of the study: The present study was undertaken for the period of 13 months from August 2010 to August 2011. Preparation of questionnaire: The questionnaire was prepared in accordance with the objectives of study. The questionnaire has two parts, one includes personal information and the other includes farm information. Analytical methods: The proximate composition of different commercial fish feeds were analyzed in duplicate according to standard procedure given in Association of Official Analytical Chemists (AOAC. 2000). Crude Protein: Crude protein of the samples was estimated by using Kjeltec 2020 digestor. A sample of 0.5 g and a blank was estimated in the digestion tube. For digestion at high temperature, 10 ml of concentrated sulfuric acid and 1.1 g digestion mixture were added in the tube. Then the digestion tubes were set in digestion chamber fixing at 420⁰C for 45 minutes ensuring water supply, easier gas outlets etc. After digestion the tubes were allowed to cool and 5 ml of sodium thio-sulphate (Na₂S₂O₃, 33%) and 30 ml sodium hydroxide (NaOH) solution was added in each tube. Then the distilled extraction was collected with 25 ml of Boric acid (4%) and titrated with standard hydrochloric acid (0.2N). The nitrogen values obtained was converted into percentage of crude protein by multiplying with a factor of 6.25 assuming that protein contains 16% nitrogen. Crude Lipid: Crude lipid was determined by extracting a weighed quantity (2-3 g) of samples with analytical grade acetone in ground joint Soxhlet apparatus. Extraction was allowed to continue by heating in the electric heater at the temperature of 70⁰C until clear acetone (without oil) was seen in siphon, which took about 3 hours. Then the round bottom flask of the apparatus was separated and the extract was transferred to a pre-weighed beaker and left for evaporation of acetone. After the evaporation of acetone, only the lipid was left in the beaker which was later calculated in percentage. Crude Fiber: A small amount of finely ground sample (1-2 g) was taken into a filter crucible and was inserted into the hot extraction unit (Hot Extractor, Model-1017). Sufficient amount of pre-heated 0.128M H₂SO₄ was added into the reagent heating system and few drops of octanol were added through the valves. The mixture was digested for 30 minutes. Acid was then removed from it by filtering and washing with boiling water. The residue in the flask was boiled with required amount of 0.223M KOH for 30 minutes and then filtered with subsequent washing in boiling water and acetone. The residual content was then dried in an oven at 105⁰C for a few hours and then ignited in muffle furnace at 550⁰C for 3 hours. The loss of weight represented the crude fiber.

Achievement/Findings:

During the study period it was found that about 90% farm used supplementary feed made by different companies and only 10% farm owners used homemade feed. Different types of factory feeds are used in Fulpur upazila. Most of these feeds are local ingredients of which were not known to farmers. Hasan and Ahmed (2001) reported that mediated feeds were often used indiscriminately during disease outbreaks in hatcheries, nurseries and farms. Among the commercial fish feed tested the highest value of moisture was found in Aftab feed, protein in Nourish feed, lipid in CP feed, ash in Aftab feed, fibre in ACI feed and carbohydrate in ACI feed. Most of the commercial fish feed maintain standard level of chemical composition. As the manufacture of aqua feeds is new to Bangladesh, no specific regulations are existent to control their processing or sale. Therefore, it is necessary to take additional steps to enforce regulatory laws for the products and marketing of fish feed for the safeguard of the fish farmers and fish production. Each manufactured productions must be tested and certified by the government authority before marketing under the regulations to be practiced.
