The main target species of Japanese purse seine operating in the tropical waters of the western Pacific Ocean is skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares), which account for nearly 98 % of their total catch in weight and the remaining is bigeye tuna (Thunnus obesus) according to the catch based on logbook data. The recent study of the vertical distribution of the...

With the decline of many exploited fish populations, catch and release has become an increasingly usedmanagement practice to allow sport fishing while reducing its impact on wild populations. However, survival and reproductive success can vary according to the catch and release technique and environmental conditions, suggesting a potential impact of this practice on prespawning behaviour. Here ...

Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...

—We present a population dynamics model based on the life history of anadromous Alosa. The model is built around a catch-at-age array to which we have added an additional dimension to include previous spawning history. The previous spawning history determines the number of times that a fish is exposed to riverine impacts that contribute to overall mortality rates. The model is designed to incor...

Chromosome 22ql1 fluorescence in situ hybridisation (FISH) studies were performed on 33 consecutive individuals attending a paediatric cardiology clinic with tetralogy of Fallot. Seven children had 22qll microdeletions but only four had other clinical features associated with the newly recognised chromosome 22 deletion syndrome (CATCH 22). Chromosome 22qll FISH studies should therefore be perfo...

"Three tribes of Babylonians," Herodotus wrote, "eat nothing but fish, which they catch and dry in the sun. They pound the dried fish in a mortar with a pestle and sift through a cloth then mix with liquid and bake like bread." Such are their customs, he reported, "Having no physicians, they bring the sick to the agora to receive advice from passers-by who have similar ailments."

The high price of flying fish eggs in Japan encourages South Sulawesi fishermen in Indonesia to harvest increasing quantities of eggs every year. Similarly, the increasing local demand for flying fish encourages Indonesian fishermen to use gill nets to catch more fish. As a consequence of this increasing quantity of eggs harvested and fish caught, Indonesia has become concerned about the overex...

Global change has generated challenges for oceans, from individuals to the entire ecosystem, and raised contemporary issues related ocean conservation management. Specifically, coral reef ecosystems have been exposed various environmental human disturbances. In this study, Ecopath with Ecosim model was used explore impacts of warming fishing on Xisha Islands ecosystem in South China Sea. The va...

Archer fish can shoot down insect prey with a sharp jet of water. Fish usually fire from positions that are not directly below their target so that a dislodged insect falls ballistically with a horizontal velocity component. Only 100 ms after the insect is on its path both the shooter and other school members can initiate a rapid turn and then head straight in the direction of the later point o...
