Compatibility of mulberry silk fabric with cow nappa leather for product development

The present work describes the application of silk fabric for leather garments and goods to support the leather products industry in identifying alternate raw material. The results show that the quilted silk fabric has the potential to be combined with cow nappa leather to make products with improved strength and enhanced aesthetic appeal. The major findings of this study also prove that on treatment with artificial alkaline perspiration, leather and silk-based samples behave inversely and this relation gives a clear direction to product designers and developers about the placement of leather and silk panels while making combination products. Apparently, this study helps the silk industry to attain the major share in the domestic and global market.

Amino acid and fatty acid compositions of Chanos chanos larvae

Not AvailableAmino acid (AA) and fatty acid (FA) composition of the fertilised eggs and different larval stages (at 0, 3, 6, 9, 12, 15 and 21 days post-hatch, dph) of Chanos chanos was investigated. The total indispensable amino acids (IAA) contributed to 55.62% of the total AA in the egg which reduced to 52.54% on 6 dph. The AA profile of C. chanos was found to be rich in valine (7.99%), leucine (7.51%) and lysine (6.98%) and poor in histidine (2.36%) and methionine (2.47%), indicating a high valine, leucine and lysine requirement. The docosahexaenoic acid (DHA) content recorded for egg, newly hatched larvae (NHL) and 21 dph larvae were 2.77, 1.36 and 1.94 mg g-1, respectively. The reduction of fatty acids (FAs) was found to be very high in newly hatched larvae (NHL), especially that of DHA (51%), ARA (26%) and EPA (24%), which indicates the significance of these FAs during the embryogenesis of milkfish egg. The trend observed during different stages of AAs and FAs content indicates their requirement during the larval period and those values are to be considered while formulating feeds for larval stages of milkfish.Not Availabl

Not AvailableIntegrated multi-trophic aquaculture (IMTA), farming of species from different trophic levels and with complimentary ecosystem function, is regarded as a suitable approach to develop a sustainable aquaculture system. In order to establish an IMTA system, a study was carried out in Sindhudurg District, Maharashtra, India for selected tropical brackish-water species. Two equal sized pens (250 m2) were constructed for IMTA and control respectively in each land based system and open water cages were set in the estuary. Different combinations of fed species (Chanos chanos, Etroplus suratensis, Mugil cephalus, Penaeus indicus) and an extractive crop (Crassostrea madrasensis) were stocked in IMTA experimental system whereas monoculture of P. indicus served as control. Water quality characteristics were found to be within the admissible limits. Soil organic carbon was found to be lesser in the IMTA system compared to control. The productivity of IMTA system was higher than control: 3250 kg h-1 vs 2000 kg ha-1. Further, income and benefit-cost ratio was found to be higher in IMTA pens. The present study concludes that IMTA is a possible option for system diversification as well as species diversification without compromising economic profitability of culture.Not Availabl
