Mitochondrial DNA analysis of North Pacific sword-fish Xiphias gladius population structure

Population Structure of Australian Swordfish, Xiphias gladius

An oceanographic characterization of swordfish (Xiphias gladius) longline fishing grounds in the springtime subtropical North Pacific

During January–May, surface manifestation of multiple, individual basin-scale fronts accentuate the central North Pacific Subtropical Frontal Zone (STFZ) system. The most prominent of these fronts are climatologically located at 32 )34 N and at 28 )30 N latitudes [herein nominally referred to as the ‘Subtropical Front’ (STF) and the ‘South Subtropical Front’ (SSTF), respectively], although cons...

A 1 lozyme variability in two samples of swordfish , Xiphias gladius L . , in the North Pacific Ocean

The swordfish, Xiphias gladius L., is a cosmopolitan species found in all tropical and temperate oceans (Nakamura, 1983). It is an esteemed food fish and subject to a multinational fishery throughout its range of distribution (Sakagawa, 1989). In 1991 the Pacific catch was 29,245 metric tons (t) or about 44% of the total global catch of 67,142 t (FAO, 1993). A variety ofpopulation structures ha...

Structure and migration corridors in Paci®c populations of the Sword®sh Xiphius gladius, as inferred through analyses of mitochondrial DNA Abstract The sword®sh Xiphias gladius is a migratory oceanic species distributed in subtropical and temperate waters worldwide. Studies utilizing mitochondrial DNA (mtDNA) have demonstrated genetic subdivision between ocean basins, as well as within the Atla...

Nuclear and mitochondrial patterns of population structure in North Pacific false killer whales (Pseudorca crassidens).

False killer whales (Pseudorca crassidens) are large delphinids typically found in deep water far offshore. However, in the Hawaiian Archipelago, there are 2 resident island-associated populations of false killer whales, one in the waters around the main Hawaiian Islands (MHI) and one in the waters around the Northwestern Hawaiian Islands (NWHI). We use mitochondrial DNA (mtDNA) control region ...
