Report of Potato grouper and Cloudy grouper in fishery landings at Mumbai
Grouper fishery of Maharashtra is dominated by
Epinephelus diacanthus with occasional landing of
E. bleekeri, E. malabaricus, E.coioides, E.
areolatus, E. polylepis, E. morrhua, E. latifasciatus,
E. epistictus, E. radiatus and Cephalopholis
sonnerati. During the routine fishery survey at
Sassoon Dock on 9th October 2016 a single specimen
of Potato grouper Epinephelus tukula measuring 35
cm TL (1.7 kg) was observed in the landings of a
trawler operated at a depth of 40 off Ratnagiri.
Reports of E. tukula is rare from Indian coast and
other reports are from Lakshadweep, Vizhinjam
(Kerala), Grand Island (Goa), Muttom, Enayam
(Tamil Nadu) coasts (Sluka and Lazarus, 2010 Marine
Biodiversity Records 3:1-3). Potato grouper, is a
widely distributed Indo-Pacific species, but sparsely
known in their distribution range from Red Sea to
Kenya and Australia. The name refers to the potatoshaped
dark blotches on the body
The pressure-amorphized state in zirconium tungstate: a precursor to decomposition
In contrast to widely accepted view that pressure-induced amorphization arises due to kinetic hindrance of equilibrium phase transitions, here we provide evidence that the metastable pressure-amorphized state in zirconium tungstate is a precursor to decomposition of the compound into a mixture of simple oxides. This is from the volume collapse ╬ФV across amorphization, which is obtained for the first time by measuring linear dimensions of irreversibly amorphized samples during their recovery to the original cubic phase upon isochronal annealing up to 1000 K. The anomalously large ╬ФV of 25.7 ┬▒ 1.2% being the same as that expected for the decomposition indicates that this amorphous state is probably a precursor to kinetically hindered decomposition. A PтАУT diagram of the compound is also proposed
Artisanal longline fishing for high value fishes off Mumbai, Maharashtra
Sassoon Dock is one of oldest and a major landing
center located in Mumbai from where several
multiday and single day fishing vessels including
trawlers, dolnetters, gillnetters and hook and line
units operate. Marine fisheries of Maharashtra is
mostly dominated by trawlers and dolnetters while
line fishing is done by only a few fishers. The
artisanal fishers in Juhu, Colaba and nearby areas
of Mumbai are operating a few long line units in
small wooden boats (6 - 7 m OAL) or fibre boats
fitted with engines of 16 тАУ 24 hp from Sassoon Dock
landing centre
Report of dorsal fin abnormality in silver pomfret
During a routine sampling for silver pomfret
Pampus argenteus, specimens with dorsal fin
abnormality were collected from Ratnagiri and
Mumbai, Maharashtra. On 29th April, 2016 a single
silver pomfret with deformed dorsal region and a
deep pit in the dorsal region was observed in the
purse seine landings at Mirkarwada fish landing
centre, Ratnagir
Turtle conservation activities in Tambaldeg village, Sindhudurg district, Maharashtra
Tambaldeg village in Devgad taluka is a famous
tourist place in the Sindhudurg district. During a
field visit to Tambaldeg beach on 24th April 2017,
six carcasses of adult olive ridley turtle
Lepidochelys olivacea and one of green turtle
Chelonia mydas were observed in decomposed
state. This beach is a turtle nesting site and the
Forest department of Maharashtra with the support
of local fishers is undertaking awareness programs
for turtle conservation including hoardings
displayed on conservation of turtles along the
beach. Protection of nesting turtles and eggs is
also undertaken by the local communities
Deep-sea chondrichthyan composition and abundance in Andaman waters, Indian EEZ-preliminary results based on exploratory survey
Two deep-sea fishery surveys were conducted during 2015 to explore the fish diversity and fishing grounds. Seven deep sea bottom trawl operations were conducted using HOT and HSDT-IInets
Preliminary study on the length-weight relationship of Sacura boulengeri (Heemstra, 1973) from Indian waters
Sacura boulengeri (Heemstra, 1973) is a rare serranid fish (Subfamily: Anthiinae) having very distinct
distribution in the western Indian Ocean. The rarity of the species is evident from earlier reports and, so far, no related
studies on the species have been published except on taxonomy and distributional records. In the present investigation,
the length-weight relationship of Sacura boulengeri was estimated to be W = 0.0777 ├Ч L2.690 (with 95% confidence
intervals for b and r2). An analysis of the stomach contents revealed that sergestid shrimps and copepods were the major
food items of the diet
First record of the Garman's lanternfish Diaphus garmani (Family: Myctophidae) from Indian waters
The myctophid Diaphus garmani is recorded for the first time from Indian waters. Three specimens (54-59 mm standard length) were collected from deep sea shrimp trawlers off Quilon, southwest coast of India, between 80 -110 N and 740-760 E, at depths from 250 to 450 m
Blue whale washed ashore at Kuttayi Landing Centre, Malappuram, Kerala
On 27th February 2010, a blue whale,
Balaenoptera musculus, measuring 31 feet in total
length was washed ashore at Kuttayi Landing Centre
in Malappuram District of Kerala
