Complete mitochondrial genome of the longfin mako shark, Isurus paucus (Chondrichthyes, Lamnidae).
Here we describe the complete mitochondrial genome sequence of the longfin mako, Isurus paucus, which is a pelagic shark found in temperate and tropical waters. The circle genome (16,704 bp) consists of 13 protein coding, 22 tRNA, 2 rRNA genes and 1 control region. It has the typical vertebrate mitochondrial gene arrangement.

متن کاملFatty acid profile and assessment of heavy metals content of Sardina pilchardus captured in the Algerian coast
Total lipids, fatty acid composition and heavy metal content of Sardina pilchardus fillet samples captured in February 2014 in Beni saf, Mostaganem, Ghazaouet, Algiers and Jijet coast were evaluated. Total lipid content was related to the five sites of catch (p < /em>< 0.05). Concerning the heavy metals, the levels of lead (Pb) ranged from 0.013mg to 0.024mg, however those of mercury (Hg) varie...
متن کاملHigh survivorship after catch-and-release fishing suggests physiological resilience in the endothermic shortfin mako shark (Isurus oxyrinchus)
The shortfin mako shark (Isurus oxyrinchus) is a species commonly targeted by commercial and recreational anglers in many parts of the developed world. In Australia, the species is targeted by recreational anglers only, under the assumption that most of the sharks are released and populations remain minimally impacted. If released sharks do not survive, the current management strategy will need...
متن کاملOxygen utilization and the branchial pressure gradient during ram ventilation of the shortfin mako, Isurus oxyrinchus: is lamnid shark-tuna convergence constrained by elasmobranch gill morphology?
Ram ventilation and gill function in a lamnid shark, the shortfin mako, Isurus oxyrinchus, were studied to assess how gill structure may affect the lamnid-tuna convergence for high-performance swimming. Despite differences in mako and tuna gill morphology, mouth gape and basal swimming speeds, measurements of mako O(2) utilization at the gills (53.4±4.2%) and the pressure gradient driving branc...
