Analysis of sex-specific spawning biomass per recruit of the sailfish (Istiophorus platypterus) in the waters off eastern Taiwan.(Report)
Jul 01, 2009; Chiang, Wei-Chuan ... Abstract--Analyses of sex-specific yield per recruit and spawning stock biomass per recruit were conducted to evaluate the current status of the sailfish (Istiophorus platypterus) fishery in the waters off eastern Taiwan. Natural mortality rates estimated from Pauly's empirical equation ...
Abundance, condition, and diet of juvenile Pacific ocean perch (Sebastes alutus) in the Aleutian Islands.(Report)
Jul 01, 2009; Boldt, Jennifer L. ... Abstract--The relative value of pelagic habitat for three size classes of juvenile Pacific ocean perch (Sebastes alutus) was investigated by comparing their abundance and condition in two areas of the Aleutian Islands. Diet, zooplankton biomass, and water column temperatures were examined ...
Modified sorting technique to mitigate the collateral mortality of trawled school prawns (Metapenaeus macleayi).(Report)
Jul 01, 2009; Broadhurst, Matt K. ... Abstract--The potential for changes to onboard handling practices in order to improve the fate of juvenile school prawns (Metapenaeus macleayi) discarded during trawling were investigated in two Australian rivers (Clarence and Hunter) by comparing a purpose-built, water-filled sorting tray ...
The repulsive and feeding-deterrent effects of electropositive metals on juvenile sandbar sharks (Carcharhinus plumbeus).(Report)
Jul 01, 2009; Brill, Richard ... Abstract--Reducing shark bycatch and depredation (i.e., damage caused by sharks to gear, bait, and desired fish species) in pelagic longline fisheries targeting tunas and swordfish is a priority. Electropositive metals (i.e., a mixture of the lanthanide elements lanthanum, cerium, ...
Effects of a large fishing closure on benthic communities in the western Gulf of Maine: recovery from the effects of gillnets and otter trawls.(Report)
Jul 01, 2009; Grizzle, Raymond E. ... Abstract--The recovery of benthic communities inside the western Gulf of Maine fishing closure area was evaluated by comparing invertebrate assemblages at sites inside and outside of the closure four to six years after the closure was established. The major restriction imposed by the ...
Development and growth of hatchery-reared larval Florida pompano (Trachinotus carolinus).(Report)
Jul 01, 2009; Riley, Kenneth L. ... Abstract--Although the Florida pompano (Trachinotus carolinus) is a prime candidate for aquaculture, the problematic production of juveniles remains a major impediment to commercial culture of this species. In order to improve the understanding of larval development and to refine hatchery ...
Use of non-natal estuaries by migratory striped bass (Morone saxatilis) in summer.(Report)
Jul 01, 2009; Mather, Martha E. ... Abstract--For most migratory fish, little is known about the location and size of foraging areas or how long individuals remain in foraging areas, even though these attributes may affect their growth, survival, and impact on local prey. We tested whether striped bass (Morone saxatilis ...
Surface mucous as a source of genomic DNA from Atlantic billfishes (Istiophoridae) and swordfish (Xiphiidae).(Report)
Jul 01, 2009; Hoolihan, John P. ... Abstract--Procedures for sampling genomic DNA from live billfishes involve manual restraint and tissue excision that can be difficult to carry (mr and may produce stresses that affect fish survival. We examined the collection of surface mucous as a less invasive alternative method for ...
Assessment of habitat quality for juvenile California halibut (Paralichthys californicus) in a seasonally arid estuary.(Report)
Jul 01, 2009; Lopez-Rasgado, Francisco Javier ... Abstract--We evaluated habitat quality for juvenile California halibut (Paralichthys californicus) in a Pacific Coast estuary lacking in strong salinity gradients by examining density, recent otolith growth rates, and gut fullness levels of wild-caught and caged juveniles for one year ....
Spatial and seasonal relationships between Pacific harbor seals (Phoca vitulina richardii) and their prey, at multiple scales.(Report)
Jul 01, 2009; Grigg, Emma K. ... Abstract--Knowing where pinnipeds forage is vital to managing and protecting their populations, and for assessing potential interactions with fisheries. We assessed the spatial relationship between the seasonal distribution of Pacific harbor seals (Phoca vitulina richardii) outfitted with ...
Use of pop-up satellite archival tag technology to study postrelease survival of and habitat use by estuarine and coastal fishes: an application to striped bass (Morone saxatilis).(Report)
Jul 01, 2009; Graves, John E. ... Abstract--Pop-up satellite archival tags (PSATs) have been used to study movements, habitat use, and postrelease survival of large pelagic vertebrates, but the size of these tags has historically precluded their use on smaller coastal species. To evaluate a new generation of smaller PSATs ...
Food habits of Atlantic white-sided dolphins (Lagenorhynchus acutus) off the coast of New England.(Report)
Jul 01, 2009; Craddock, James E. ... Abstract--Although the Atlantic white-sided dolphin (Lagenorhynchus acutus) is one of the most common dolphins off New England, little has been documented about its diet in the western North Atlantic Ocean. Current federal protection of marine mammals limits the supply of animals for ...
Reflex impairment as a measure of vitality and survival potential of Atlantic cod (Gadus morhua).(Report)
Jul 01, 2009; Humborstad, Odd-Borre ... Abstract--Assuring the vitality and survival potential of live-caught Atlantic cod (Gadus morhua) is important for improving the sorting of fish before net penning operations designed to hold fish for growth and later market. When Atlantic cod are captured by Danish seine, the most ...
