Pearly hairtail, Trichiurus auriga Klunzinger: A prospective non-conventional deep-sea resource

Indian coastal waters, though hugely productive and, despite bearing the major share of total marine fish landing over the past many years of the country, provide only limited scope for further production augmentation. Taking cues from the increasing demand for fishes from domestic as well as international markets that include reduction fish industry, opportunities for spatial expansion targeting non-conventional resources of the deep seas have never been abrogated by the trawler fleet across the maritime states. Thus, they have often encountered lantern fish (myctophids), unicorn leather jacket (Aluterus monoceros), smooth blaasop (Lagocephalus inermis) red toothed triggerfish (Odonus niger) etc., which added to enhance economic benefits from deep sea fishin

Bioengineered\ua0braided micro-nano (multiscale) fibrous scaffolds for tendon reconstruction

A braided multiscale fibrous scaffold consisting of aligned PCL micro/collagen-bFGFnano fibers was fabricated (mPCL-nCol-bFGF) to mimic native tendon tissue architecture which was further coated with alginate to aid in prevention of peritendinous adhesion. The bFGF release kinetics showed a sustained release of growth factors for a period of 20 days. Further, in vitro cell viability, attachment, and proliferation were performed using rabbit tenocytes under static and dynamic conditions. mPCL-nCol-bFGF showed a higher cell proliferation and enhanced expression of tenogenic markers compared to mPCL-nCol (braided scaffold without bFGF). When subjected to dynamic stimulation in a bioreactor, mPCL-nCol-bFGF-DS (braided scaffold with bFGF after dynamic stimulation) showed enhanced cellular proliferation and tenogenic marker expression, compared to mPCL-nCol-bFGF. The in vivo studies of the cell seeded scaffold after dynamic stimulation in Achilles tendon defect model showed tendon tissue regeneration with aligned collagen morphology within 12 weeks of implantation

Fishery status of large pelagic resources of Andaman and Nicobar Islands

The Andaman and Nicobar with an aggregate coastline of 1,912 km has an estimated annual harvestable potential of marine fish around 2.4 lakh tons. The fish landing data obtained from Dept. of Fisheries, UT of Andaman & Nicobar Islands was used for analysis
