Abstract:
This thesis Entitled distribution ,diversity and biology of deep-sea fishes the indian Eez.Fishing rights and responsibilities it entails in the deep-sea sector has been a vexed issue since the mid-nineties and various stakeholders have different opinion on the modalities of harnessing the marine fisheries wealth, especially from the oceanic and deeper waters. The exploitation and utilization of these esources requires technology development and upgradation in harvest and post-harvest areas; besides shore infrastructure for berthing, handling, storing and processing facilities. At present, although deep-sea fishes don’t have any ready market in our country it can be converted into value added products.
Many problems have so far confronted the deep-sea fishing sector not allowing it to reach its full potential. Hence, there should be a sound deep-sea fishing policy revolving round the upgradation of the capabilities of small scale fishermen, who have the inherent skills but do not have adequate support to develop themselves and to acquire vessels having the capability to operate in farther and deeper waters. Prospects for the commercial exploitation and utilization of deep-sea fishes were analyzed using SWOL analysis.

Abstract:
Hepcidin is cysteine-rich short peptide of
innate immune system of fishes, equipped to perform prevention
and proliferation of invading pathogens like bacteria
and viruses by limiting iron availability and activating
intracellular cascades. Hepcidins are diverse in teleost
fishes, due to the varied aquatic environments including
exposure to pathogens, oxygenation and iron concentration.
In the present study, we report a 87-amino acid (aa)
preprohepcidin (Hepc-CB1) with a signal peptide of 24 aa,
a prodomain of 39 aa and a bioactive mature peptide of 24
aa from the gill mRNA transcripts of the deep-sea fish
spinyjaw greeneye, Chlorophthalmus bicornis. Molecular
characterisation and phylogenetic analysis categorised the
peptide to HAMP2-like group with a mature peptide of
2.53 kDa; a net positive charge (?3) and capacity to form
b-hairpin-like structure configured by 8 conserved cysteines.
The present work provides new insight into the mass
gene duplication events and adaptive evolution of hepcidin
isoforms with respect to environmental influences and
positive Darwinian selection. This work reports a novel
hepcidin isoform under the group HAMP2 from a nonacanthopterygian
deep-sea fish, C. bicornis
