First report of four deep-sea chondrichthyans (Elasmobranchii and Holocephali) from Andaman waters, India with an updated checklist from the region
This paper confirms the new distributional records of four rare deep-water chondrichthyans viz. sharpnose sevengill shark, Heptranchias perlo (Bonnaterre, 1788); bluntnose sixgill shark, Hexanchus griseus (Bonnaterre, 1788); bramble shark, Echinorhinus brucus (Bonnaterre, 1788); and sicklefin chimaera, Neoharriotta pinnata (Schnakenbeck, 1931) from the Andaman waters in the Indian EEZ. The above-mentioned four fish species have not been reported earlier from this region. More exploratory surveys in the region are essential to understand the diversity and distribution pattern which is essential for critical management actions. An updated checklist of chondrichthyans known from Andaman and Nicobar waters of India is also presented

http://eprints.cmfri.org.in/id/eprint/10026 and official URL: http://biotaxa.org/Zootaxa/article/view/zootaxa.37...A new species of anthiine fish, Plectranthias alcocki n. sp. is described and illustrated based on two specimens, (63.7–72.5 mm SL), recently collected from deep-waters of the Arabian Sea, off Kollam, Kerala, India. The following combination of characters distinguishes it from all other congeners: Dorsal-fin rays X, 15; anal-fin rays III, 7; pectoral-fin rays 14, all unbranched; pelvic-fin rays I, 5; lateral-line complete, the pored lateral-line scales 28; scales above lateral line to origin of dorsal fin 1; scales dorsally on head extending to posterior nostrils; no scales on maxilla or chin; gill rakers 5 + 11 (2 + 7 developed); circumpeduncular scales 10; fourth dorsal spine longest, 2.8 (2.6) in head length (HL), longest dorsal-fin soft ray (second) 2.4 (2.7) in head length; body depth 34.4 (35)% SL; head length 46 (49.8)% SL; orbital length 8.6 in SL; margin of preopercle finely serrate, the serrae 33 (28), ventral edge without antrorse spines; dorsal fin continuous and notched; first anal-fin spine 4.9 (5.6) in HL, second anal-fin spine 2.2 (2.6) in HL; pelvic fins relatively short, 4.0–4.3 in SL; the dorsal fin with a black blotch at base of fourth to eighth spines, one at base of the last three spines, and two at base of soft portion of fin, the dark pigment extending onto adjacent body.Not Availabl
New biogeographic data and DNA barcodes for the Indian swellshark, Cephaloscyllium silasi (Talwar, 1974) (Elasmobranchii: Carcharhiniformes: Scyliorhinidae), from Andaman waters
Indian swellshark, Cephaloscyllium silasi (Talwar, 1974), is reported for the first time in Andaman waters, India which is a considerable extension of its known distribution range with more than 1000 km toward eastern Indian EEZ. This is the first confirmed geographic distributional record of poorly known deep-water Indian swellshark, C. silasi, in the Andaman waters and first outside its type locality. A detailed morphological description of C. silasi collected from Andaman waters and comparison with other known materials along with the molecular barcodes are provided
First report of <em>Tristomella laevis</em> (Verrill, 1875) Guiart, 1938 parasitic on <em>Istiophorus platypterus</em> (Shaw and Nodder, 1792) from Andaman Sea
1616-1619Tristomella laevis was recorded from the pectoral fins of Indo–Pacific sailfish, Istiophorus platypterus caught by the tuna longliner MFV Blue Marlin from Andaman Sea. The infested fish was of length 213 cm (Lower Jaw fork Length (LJFL) and weighed 45kg. All Six numbers of parasites were collected from the pectoral fins and they were in the length range of 9.1–12.5 mm. No gill damage was observed

Not AvailableAlthough the species is known to Western Pacific and
Indian ocean from Marshall island to Japan to southern
Africa and Red Sea; eastern Mediterranean from port
Said to Gulf of Sirda and Near Rhodes Islands (Ben- Tuvia
1966; Fischer & Bianchi 1984; Parin 1986), the present
study records a new geographic distribution of P. mento.
Hence the Andaman waters as mentioned previously
may harbour two Parexocoetus species, P. brachypterus
and P. mento, similar as per the conclusion of Fischer &
Bianchi (1984) from the Mediterranean Sea.
In Andaman & Nicobar Islands, both the species are
caught in selective lesser sardine gill nets as bycatch. The
present record on the species is an additional species to
biodiversity database of fishes of Andaman waters.Not Availabl

Journal of the Ocean Science Foundation
Not AvailableWe provide an updated checklist of fishes of the families Serranidae and Epinephelidae reported or listed from India, along with photographs. A total of 120 fishes in this group are listed as occurring in India based on published literature, of which 25 require further confirmation and validation. We confirm here the presence of at least 95 species in 22 genera occurring in Indian marine waters. The majority of the species belong to the grouper genus Epinephelus (41%), followed by Pseudanthias (15%) and Cephalopholis (13%). Most species (92%) found in India have been assessed globally either as Data Deficient (DD) or Least Concern (LC) on the IUCN Red List of Threatened Species. Since information on groupers from India is limited, there is an urgent need to document the diversity, ecology, life history, population status, and fisheries status of this group of fishes from the countr
