Characterization of Myoglobin from Sardine (sardinella Gibbosa) Dark Muscle
Myoglobin from the dark muscle of sardine (Sardinella gibbosa) with the molecular weight of 15.3 kDa was isolated and characterized. The different myoglobin derivatives exhibited varying thermal unfolding characteristics. Deoxymyoglobin showed a single distinct endothermic peak at 74.5°C, whereas two transition temperatures were noticeable for oxymyoglobin (64.5°C and 78.4°C) and metmyoglobin (...
متن کاملSpatial variability of Spanish sardine (Sardinella aurita) abundance as related to the upwelling cycle off the southeastern Caribbean Sea
The Sardinella aurita fishery off northeastern Venezuela, region of seasonal wind-driven coastal-upwelling, accounts for 90% of the Caribbean Sea small pelagic catch. This law-protected artisanal fishery takes place up to ~10 km offshore. The spatial distribution, number of schools, and biomass of S. aurita were studied using eight hydro-acoustic surveys (1995-1998). The study included the anal...
متن کاملPopulation genetic structure of Indian oil sardine, Sardinella longiceps along Indian coast.
Genetic stock structure and historical demography of Indian oil sardine, a commercially and ecologically important small pelagic fish, was studied using mitochondrial control region and Cytochrome C Oxidase I (COI) sequences. A 758 bp portion of the control region in 287 individuals and a 576 bp portion of the COI gene in 291 individuals from 10 locations along the distribution range were ampli...
متن کاملGenetic Variability of Apolipoprotein E in Different Populations from Venezuela
The genetic variation at the Apolipoprotein E locus (APOE) is an important determinant of plasma lipids and has been implicated in various human pathological conditions. The objective of the present study was to estimate the distribution of APOE alleles in five Venezuelan communities: two Amerindian tribes (Bari and Yucpa), one Negroid population from Curiepe, one Caucasoid population from Colo...
متن کاملAge and growth of Sind sardine (Sardinella sindensis) using otolith from Qeshm Island (Persian Gulf)
This is the first study of growth and age of Sardinella sindensis from coastal waters of Qeshm Island (Persian Gulf) based on the sectioned otolith reading method. In total, 128 fishes were collected randomly from purse seine commercial nets during March 2011 to February 2012. The annual formation of the growth rings were determined by counting the opaque and translucent zones occurrence at the...
