The complete mitochondrial genome of the big-eye thresher shark, Alopias superciliosus (Chondrichthyes, Alopiidae).
The complete mitochondrial genome of the big-eye thresher shark was sequenced using a polymerase chain reaction (PCR)-based method. The total length of mitochondrial DNA is 16,719 bp and includes 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, 1 replication origin region and 1 control region. The mitochondrial gene arrangement of the big-eye thresher shark is the same as the on...
متن کاملAcoustic tracking of bigeye thresher shark Alopias superciliosus in the eastern Pacific Ocean
Acoustic telemetry was used to identify the short-term horizontal and vertical movement patterns of the bigeye thresher shark Alopias superciliosus in the eastern tropical Pacific Ocean during the summer of 1996. Two immature female sharks, 175 and 124 cm PCL (precaudal length), were tracked for 96 and 70 h, respectively, demonstrating very distinct crepuscular vertical migrations similar to th...
متن کاملAge and growth of the bigeye thresher shark, Alopias superciliosus, from the pelagic longline fisheries in the tropical northeastern Atlantic Ocean, determined by vertebral band counts
The bigeye thresher, Alopias supercilious, is commonly caught as bycatch in pelagic longline fisheries targeting swordfish. Little information is yet available on the biology of this species, however. As part of an ongoing study, observers sent aboard fishing vessels have been collecting set of information that includes samples of vertebrae, with the aim of investigating age and growth of A. su...
متن کاملFirst Report on Recruits of Bigeye Thresher Shark Alopias Superciliosus (Laminiformes: Alopidae) with Largest Birth Size from Indian Waters
Four embryonic bigeye thresher sharks Alopias superciliosus (126–158 cm total length) were collected from two females caught by bottom set gillnet and hook and line (operating in 120–800 m depth) caught from off Kanyakumari area and landed in Cochin Fisheries Harbour on 11-06-2012 . Detailed morphometric measurements are provided. The ratio of size at birth (Lb) and maximum observed length (L m...
