The ecological role of species can vary among populations depending on local and regional differences in diet. This is particularly true for top predators such as the bottlenose dolphin (Tursiops truncatus), which exhibits a highly varied diet throughout its distribution range. Local dietary assessments are therefore critical to fully understand the role of this species within marine ecosystems...

A bioenergetics and population dynamics coupled model that includes a full life cycle size/growth-dependent mortality function was developed to better understand stock fluctuations. As an example, the applied chub mackerel ( Scomber japonicus ) as it shows large fluctuations in western North Pacific. The dependency parameters for growth/size were adjusted achieve realistic from 1998 2018. Two t...

To evaluate the importance of northern Satsunan area in southern Japan as a spawning and nursery ground for chub mackerel ( Scomber japonicus ), we investigated early life history characteristics (e.g., larval distribution, feeding habits, growth) S. over five successive years. This is considered main habitat congeneric species, australasicus . Using polymerase chain reaction-restriction fragme...

Anisakidae are nematodes that commonly parasitize in the coelomic cavity and viscera of several fish species. They can be found flesh, which is why they have an important economic public health impact. The aim current work was to assess presence prevalence Anisakis larvae species caught coastal area Karaburun Peninsula Vlora Bay (Albania). A total 856 wild teleosts 219 specimens farmed were col...

A Real Time-PCR method based on TaqMan technology for the 14 identification of Scomber Scombrus has been developed. A system of specific 15 primers and a Minor Groove Binding (MGB) TaqMan probe based on 16 sequences of the mitochondrial cytochrome b region was designed. The 17 method was successfully tested in 81 specimens of Scomber scombrus and 18 related species and validated in 26 different...

The oceanographic conditions in the north Pacific have shifted to a colder period, Pacific sardine (Sardinops sagax) biomass has declined precipitously in the California Current, the international sardine fishery is collapsing, and mackerel (Trachurus symmetricus and Scomber japonicus) are thriving. This situation occurred in the mid-1900s, but indices of current oceanographic conditions and th...
