Post-release horizontal and vertical behavior and philopatry of deepwater longtail red snapper Etelis coruscans around a bank

Autor: Takeshi Hayashibara, Junichi Okuyama, Hirotoshi Shishidou

Publikováno v: Fisheries Science. 85:361-368

Little is known about the behavior and migration of deep-sea snappers, as observation of their deep-sea habitats is difficult. Manual acoustic tracking of deepwater longtail red snappers Etelis coruscans was conducted at the Ojika Se Bank, in the wat

Release of captively-bred individuals into the wild is one of the most popular tools in fisheries, forestry, and wildlife management, and introgression of hatchery-reared animals into wild populations is of global concern. However, research and monit

Floating seaweeds play important ecological roles in offshore waters. Recently, large amounts of rafting seaweed have been observed in the East China Sea. In early spring, juveniles of commercially important fish such as yellowtail accompany these se

Genetic effects of hatchery fish on wild populations in red sea bream Pagrus major (Perciformes, Sparidae) inferred from a partial sequence of mitochondrial DNA

Autor: Shuichi Kitada, S. Toriya, Katsuyuki Hamasaki, Takuma Sugaya, Hirotoshi Shishidou

Publikováno v: Journal of Fish Biology. 77:2123-2136

Variation in the mitochondrial DNA transcriptional control region sequence was investigated in wild and hatchery-released red sea bream Pagrus major from Kagoshima Bay, where an extensive hatchery-release programme has been conducted for >30 years. T

Publikováno v: Aquaculture. 290:69-79

Since the 1980s, there has been growing concern about the deleterious genetic effects of hatchery fish on wild populations. The general awareness of the loss of genetic variation in hatchery-produced juveniles has increased. However, the genetic effe
