Management of the eel fisheries of the River Shannon, Ireland’s largest river system, has involved van ous stock enhancement measures since 1959. Declining natural recruitmenr levels have limited the effecriveness of stocking programmes for nearly two decades. Observations on declining yellow eel stocks in several major lakes have been supported by the results of studies undertaken annually on ...

Among the various shark species that are captured as bycatch in commercial fishing operations, the group of pelagic sharks is still one of the least studied and known. Within those, the crocodile shark, Pseudocarcharias kamoharai, a small-sized lamnid shark, is occasionally caught by longline vessels in certain regions of the tropical oceans worldwide. However, the population dynamics of this s...

To estimate postrelease survival of white marlin (Tetrapturus albidus) caught incidentally in regular commercial pelagic longline fishing operations targeting swordfish and tunas, short-duration popup satellite archival tags (PSATs) were deployed on captured animals for periods of 5−43 days. Twenty (71.4%) of 28 tags transmitted data at the preprogrammed time, including one tag that separated f...

The establishment of marine protected areas (MPAs) can often lead to environmental differences between MPAs and fishing zones. To determine the effects on marine dispersal of environmental dissimilarity between an MPA and fishing zone, we examined the abundance and recruitment patterns of two anemonefishes (Amphiprion frenatus and A. perideraion) that inhabit sea anemones in different managemen...

The potential population and community level impacts of fishing have received considerable attention, but little is known about how fishing influences communities' functional diversity at regional scales. We examined how estimates of functional diversity differed among 25 regions of variable richness and investigated the functional consequences of removing species targeted by commercial fisheri...

Identification of active compounds from natural products is a critical and challenging task in drug discovery pipelines. Besides commonly used bio-guided screening approaches, affinity selection strategy coupled with liquid chromatography or mass spectrometry, known as ligand fishing, has been gaining increasing interest from researchers. In this review, we summarized this emerging strategy and...

The public perception of fisheries is that they are in crisis and have been for some time. Numerous scientific and popular articles have pointed to the failures of fisheries management that have caused this crisis. These are widely accepted to be overcapacity in fishing fleets, a failure to take the ecosystem effects of fishing into account, and a failure to enforce unpalatable but necessary re...

Illegal, unreported and unregulated (IUU) fishing activities continue to thrive in the northern region of Australia’s Fishing Zone (AFZ). Indonesian fishermen involved in IUU fishing in this area target specific marine species such as shark, reef fish, sea cucumber and trochus that are destined for the Asian market. Many of these marine species’ stocks are now at critical levels. Local communit...

A field trial was conducted to determine the effect of acoustic deterrent devices (ADDs, or pingers) on harbour porpoise (Phocoena phocoena) and seal (Phoca vitulina) bycatch in three Norwegian commercial gillnet fisheries targeting cod (Gadus morhua), saithe (Pollachius virens) monkfish (Lophius piscatorius). Catch data 3500 net-km-days were collected by 8 fishing vessels operating gillnets hi...

Sustainable marine fishing practices are often hindered by local-level factors in areas with high fishery potentials, such as Odisha, India. Scientific services to fishing, Marine Fishery Advisories (MFAs) on the Potential Fishing Zone (PFZ) and weather information form of Ocean State Forecast (OSF) advisories provided INCOIS, India, valuable knowledge products which can help fishers overcome s...
