The present study has been undertaken to assess the training needs of employer on cleaner production in SAF leather industry at Jashore district in Bangladesh. Using Borich Need Assessment Model for training needs. A total 60 employers were surveyed including 20 employers from each group and data were collected on socioeconomic condition of responders, management activities in leather processing and environment pollution related issues through the questionnaire. The importance level, competence needs were analyzed and ranked using weighted discrepancy scores (WDS). The study revealed that the highest WDS score (15.38) was found for Beam house worker that indicated the training is strongly needed for them on identification of harmful chemicals and environmental pollution. Crust and fishing unit worker needed high training (WDS score= 15.10) on understanding the types and quantities wastewater discharged from industry during leather processing and its management. The WDS score 14.78 was estimated for administrative employers where they needed high training on controlling odor problem from the industry. Although they have an average knowledge about the environmental pollution, they did not have qualified level of capabilities on understanding how to use some environmental tools e.g. social impact assessment and environmental auditing. Therefore, majority of the respondents preferred training for reduction of environmental pollution.
An experiment was carried out to comparative analysis of nutritional quality of different fish feed from different feed dealers and industries in greater Noakhali region and to compare the values with those provided by the manufacturers. The feed samples were collected from different feed industries and dealer's shop of these region. Feed samples were collected during 10 August to 5 September, 2016. The collected feed samples were stored and analyzed in the Fish Nutrition Laboratory of the Department of Aquaculture in the Faculty of Fisheries, Bangladesh Agricultural University (BAU), Mymensingh for proximate composition (moisture, ash, crude protein, crude lipid, crude fiber, carbohydrate) following standard methods. Results showed that there was significant variation between analyzed and company provided nutritive values of different feeds. Some feed samples have low moisture level (difference 0.7 to 3.3%). Ash content of the experimental samples also show a variety of results compared to their labeled composition. Only some feed have more values to the company provided values, such as, Mega starter (12.13%) and Bengal grower (12.75) proportion with 12%. Some feed contains more difference range of 6.01% more than labeled values is RP feed (20.01%). Maximum feed samples had lower crude protein (difference 0.05 to 4.65%) than the company provided protein values. However, only crude protein of Bengal finisher (29.95%) and Aftab grower (28.07%) feeds were found to be almost same to the company provided nutritive values (30% and 28%). The lipid, ash and carbohydrates contents of the experimental samples also have a difference range. The highest lipid values are available in Provita starter (9.76%) and lowest values containing feed Setu grower (4.33%). The highest carbohydrates content in the feed Provita starter (36.84%). The findings of this study demonstrated that low quality commercial fish feeds were supplied to the fish farmers by majority of feed companies. Therefore, the study will generate some information to the farmers which will help to choose the best feed for their aquaculture production.
