A new species of spider crab is described from two male specimens collected from the southeastern Arabian Sea. This species differs from its congeners in the absence of uograstric granule on carapace, the presence of two granules along lateral margin of carapace at branchial region, the presence of granules on P2–P4 dactyli and the constricted distal tip of the male first gonopod.

A New Species

Newtoniellinae is a worldwide marine group of cold-water, deep-sea species, comprising the genera Cerithiella, Paramendax and Trituba. Prior to this study, the subfamily was represented in Brazil by four species of Cerithiella. The present contribution adds new Brazilian records of two of these species, Cerithiella amblytera and Cerithiella enode, in addition to new records of two species previously known only from Cuba and the south-eastern USA, respectively: Cerithiella sigsbeana comb. nov. and Cerithiella producta. Two new species of Cerithiella from Brazil are described: Cerithiella atali sp. nov. has a pointed protoconch identical to the species described in the previously synonymized genus Stilus; Cerithiella candela sp. nov. has the teleoconch very similar to Cerithiella pernambucoensis, but is differentiated by the protoconch morphology. Also, a new species of Trituba is described, Trituba anubis sp. nov., which is the second species of this genus recorded for the western Atlantic. Eumetula axicostulata comb. nov. and Eumetula vitrea comb. nov., both from the western Atlantic but not recorded from Brazil, are transferred from the genus Cerithiella. This study increases from four to nine the number of known species of Newtoniellinae from Brazil.

Moray Eel

A new species of white-spotted moray eel Gymnothorax smithi sp. nov. is described based on three specimens collected from the southeastern Arabian Sea, India. This is the first deep water report of a moray eel from Indian waters from 200 m depth. This new species is distinguishable from its congeners by the following combination of characters: greyish brown body overlain with white spots of irregular shape, dorsal-fin origin anterior to gill opening, anus positioned slightly behind the mid-point of the body, serrated teeth and a unique vertebral count 3–5 /57/130–132.

A New Species

Symphysanodon xanthopterygion, new species, reported herein from 15 specimens collected near Quilon, India, off the Kerala Coast in the southeastern Arabian Sea, becomes the twelfth described species in the genus. The following characters in combination distinguish S. xanthopterygion from its congeners: parapophyses present on first caudal vertebra, total number of gillrakers on first arch 38 to 42, tubed lateral-line scales 54 to 59, sum of lateral-line scales plus total number of gillrakers in individual specimens 94 to 101, head length 33 to 37% SL, head depth 18 to 21% SL, snout length 5 to 6% SL, body depth 24 to 27% SL, lower caudal-fin lobe bright yellow.

Abundant Population

Diet analysis of 1190 fishes belonging to 17 species of deep sea fishes were conducted. The samples were collected from the South-eastern Arabian Sea in bottom trawl by the research vessel FORV Sagar Sampada (cruise no. 322 and 345) during January 2014 and October 2015, between lat. 7- 150N and long. 78 - 720E in the depth range 200 - 1000 m. Diet composition, feeding strength, size range, depth range, distribution and index of preponderance were ascertained for all the species. It was observed that the deep sea fishes mainly feed on benthic and epibenthic organisms such as fishes, shrimps, crabs and squids, revealing their carnivorous nature. Deep sea shrimps are one of the major diet components of these fishes, which is an indication of the availability of good quantity of deep sea shrimps, along the South-eastern Arabian Sea and this abundant population can be commercially utilised in order to lessen the pressure of overexploitation being experienced in case of coastal shrimps.

Slow Growing

In the absence of direct consumption importance and considering as low value bycatch, many vulnerable non-target species, especially slow growing deep water fauna, are overlooked in tropical fisheries research and management. The bramble shark Echinorhinus cf. brucus (Bonnaterre, 1788) is one such species, subjected to a significant non-targeted deep water fishery off southern India. A length frequency based stock assessment of bramble shark caught in trawl fisheries from the south-eastern Arabian Sea suggests that, E. cf. brucus is a moderately slow growing (K=0.12 year-1) and moderately long lived shark species (Tmax = 25 years, L¥= 333 at corresponding age of 55 years) which is overexploited (M=0.17, Z=0.39) in the region. In view of resilience capacity and vulnerability of deep sea fisheries, improved research and monitoring programmes are urgently required to ensure a sustainable future for India’s expanding deep-sea and distant water fisheries.

The paper presents the first detailed study on systematics, otolith structure and biology of Diaphus coeruleus, from the south-eastern Arabian Sea. The closely related and co-inhabiting species D. coeruleus and D. watasei are distinguished on the basis of morphometric, meristic and otolith characters. Analysis of gut content revealed that these fishes mainly feed on deep sea squids and shrimps. Six maturation stages of gonads are identified in males (immature, quiescent, mature, ripe, spawning and spent) and five stages (immature, quiescent, mature, ripening and spawning stages) in females. Overall sex ratio deviated in favour of males (1 male: 0.2 female) and the mean fecundity was 2150 ± 353 eggs. The length-weight relationship shows an overall isometric growth in males with N = 76 and b = 3.13 and for females with N = 17 and suggests negative allometric growth (b = 1.719). Otolith length (LO) and otolith weight (WO) are positively correlated to standard body length (LS) and body weight (BW).
