    ABSTRACT: The growth promoting potential of fruits wastes, mango seed kernel, banana peel and papaya peel on the freshwater prawn, Macrobrachium rosenbergii post larvae (PL) was evaluated. Basal diet equated to 35% protein was prepared by using soybean meal, groundnut oilcake, horse gram and wheat flour. Each fruit waste powder was separately incorporated with basal diet at a proportion of 10%. Sunflower oil was used as lipid source. Egg albumin and tapioca flour were used as binding agents. Vitamin B-complex with Vitamin-C was also mixed. Feed without any fruit waste was served as control. M. rosenbergii PL (length: 1.2-1.4 cm; weight: 0.09-0.13 g) was fed with these feeds for a period of 90 days. Significant improvements in the nutritional indices (survival rate, weight gain, biomass index, specific growth rate and condition factor), concentrations of biochemical constituents (total protein, carbohydrate and lipid), levels of non-enzymatic antioxidants (vitamin-C and E), content of minerals (Na + and K +), activities of digestive enzymes (protease, amylase and lipase), and profiles of essential amino acids and fatty acids were recorded in fruits wastes incorporated feeds fed PL when compared with control (P< 0.003 – 0.878). The overall results indicated the fact that mango seed kernel incorporated feed was produced the best performance, followed by better performance of banana peel and good performance of papaya peel. These fruits wastes incorporated feeds enhance digestive enzymes activities and act as appetizer, which in turn enhances food utilization and ultimately yielded better survival and growth of M. rosenbergii PL. Therefore, these fruits wastes have considerable potentials in sustainable development of Macrobrachium culture.

    ABSTRACT: BACKGROUND: Certain crop-based waste materials have been recognized as cost-effective and highly efficient adsorbents for removal and recovery of different kind of heavy metals from aqueous solutions. The ability is strongly attributed to the carboxyl functional group of some pectin substances such as galacturonic acid often found in fruit peels. The present manuscript was aimed at assessing the potential applicability of banana peel for metal removal from contaminated waters. METHODS AND RESULTS: As revealed by laboratory investigations, banana peel contains pectin (10-21%), lignin (6-12%), cellulose (7.6-9.6%), and hemicelluloses (6.4-9.4%). The pectin extraction is reported to have glucose, galactose, arabinose, rhamnose, xylose, and galactouroninc acid. Several studies conducted under different conditions proved that banana peel is capable of adsorbing 5.71, 2.55, 28.00, 6.88, 7.97, and 5.80 mg/g of Cd2+, Co2+, Cu2+, Ni2+, Pb2+, and Zn2+, respectively, from aqueous solutions. Adsorption capacity is, however, dependent upon several factors including solution pH, dose of adsorbent and metal concentration, contact time and shaking speed. CONCLUSION(S): Since the annual world production of banana exceeds 100 million tons, about 40 million tons of banana peel (40% of total weight of the fresh fruit) remains vastly unused. Exploring a sound technology with banana peel would therefore, not only address the much needed sustainable tool for cleaning contaminated waters, but of course bring an additional value to the banana industry worldwide.
