On the equisummability of Hermite and Fourier expansions
We prove an equisummability result for the Fourier expansions and Hermite expansions as well as special Hermite expansions. We also prove the uniform boundedness of the Bochner-Riesz means associated to the Hermite expansions for polyradial functions
Status of Bioprospecting of Marine Molluscs in India
Continuous pressure on the environment arising inevitably or otherwise out of technological progress and human
population growth has made it necessary to place a commodity value on biodiversity (Randall, 1991)
Record landings of cephalopods by trawlers at Veraval during first quarter of 2009
Cephalopods represent one of the most
important exploited marine fishery resources at
Veraval. The cephalopod landings in Gujarat
increased by more than two folds from 0.234 lakh t
in 2002 to 0.49 lakh t in 2006 (Mohanraj et al., 2009),
with a concomitant increase in catch rate from 5.05
kg h-1 in 2003 to 14.74 kg h-1 in 2006. The cephalopod
resource was constituted mainly by Loligo duvauceli,
Sepia pharaonis and S. aculeat

By-catch of the gastropod Tibia spp. in gillnets operated along Gujarat coast
The rocky coastal belt of Gujarat possesses an
enormous potential resource of lobsters. Gillnets are
regularly operated for lobster along the coast of
Mangrol, Porbunder and Muldwarka. Gastropods
such as Tibia maculata and Tibia curta occurred in
large quantities as by-catch along with lobsters.
Other gastropods such as Archipecten sp. and
Murex sp. also make their occurrence in small
quantities
