The assembly and annotation of a genome is valuable resource for species, with applications ranging from conservation genomics to gene discovery. Genomic development especially important species in culture, such as the California Yellowtail (Seriola dorsalis), likely candidate establishment commercial offshore aquaculture production southern California. this will improve understanding sex other phenotypic traits, allow rapid increases genetic improvement economic gain culture production.

ABSTRACT The silky shark ( Carcharhinus falciformis ) has the highest bycatch in gillnets, longlines, and purse seine globally. Its thermal depth preferences coincide with tropical tuna habitat, indicating a high capture vulnerability by these fisheries. present research seeks to determine environmental conditions that favor distribution identify areas probability of occurrence. data analyzed correspond records Eastern Pacific Ocean (EPO) published Inter‐American Tropical Tuna Commission...
Climate regime shifts in the Northeast Pacific appear to have forced population size changes associated with major geographical variations position of center distribution and bulk biomass sardine (Sardinops caeruleus). These findings help explain disappearance sardines around 60 years ago at northern part California Current System their return following 1980s. The spatial processes described here differ from those suggesting that environmental lead progressive increasedecrease stock...
The objective of the study was to identify key elements feeding ecology dolphinfish, which is a high tropic predator important for sport and artisanal fishing in Mexican Pacific. Feeding habits were investigated during years 2000–2003. This species seasonal southern Gulf California probably remains there because abundant prey. contents 232 dolphinfish stomachs analyzed, identifying 98 prey species, although only eight these well-represented diet. most by weight fish Hemiramphus saltator,...
Abstract Determining what animals eat is simultaneously challenging and yet also critical for ecologists, fisheries scientists, resource managers. The tools of trophic ecology have expanded considerably in the last half century pursuit this goal. In study, we combined stomach contents, stable isotope, fatty acid analyses to investigate patterns three species highly mobile, pelagic predators: striped marlin (Kajikia audax), blue (Makaira nigricans), common dolphinfish (Coryphaena hippurus)....
Stable isotope values of Kajikia audax (Philippi, 1887) and Makaira nigricans (Lacepede, 1802) were analyzed to detect differences associated with trophic segregation influenced by their feeding habits in the southern Gulf California, Mexico. We sampled dorsal white muscle 47 M. 35 K. collected from 2005 2007. No relationship was found between billfish body size isotopic values.

Abstract Using data from analyses of stomach contents and stable isotopes, we examined high‐resolution variations in the feeding habits trophic position Dolphinfish Coryphaena hippurus during 2005–2007. In total, 418 specimens were collected off southern Baja California peninsula, Mexico. Based on analysis (% index relative importance [%IRI]), consumed mainly epipelagic prey, with red crab Pleuroncodes planipes as most abundant prey species. The diet was highly similar between sexes but...
Oceanic mesoscale events such as eddies, coastal upwelling, filaments and fronts created by water mass intrusion present properties allowing them to concentrate, transport disperse salt, nutrients plankton, among other important constituents in the ocean. The use of satellite images enables continuous monitoring ocean dynamics at different temporal spatial scales, aiding study its variability. This focuses on identification these Gulf California (GC) means sea surface temperature (SST)...
Dolphinfish (Mahimahi) are a high-demand resource for sport and coastal fisheries, mainly in the Pacific Ocean. Due to their economic ecological importance, studies of biology very important understand function ecosystems. We used stable isotope stomach content analyses determine most prey common dolphinfish, as well trophic level this species two areas southern Gulf California. Stomach contents 445 specimens were analysed. Using both techniques, we found that dolphinfish California three...
Cabo San Lucas, Baja California Sur, Mexico, is the main sportfishing location for striped marlin, with a mean annual catch rate of 0.6 fish per fishing trip. In present study, interannual and seasonal variation rates from 1990 to 1999, their relationship monthly sea surface temperatures were analysed. Although was not significant, effect showed significant differences, highest average in winter, lowest summer (0.9 0.3 respectively). An difference decreasing tendency length analysis....
Catch data of the yellowfin tuna (YFT) fishery were used to study relationship between seasonal and spatial variations YFT with or without presence mesoscale structures at entrance Gulf California (19º–24º N, 104º–112º W). The catches distributed mainly over continental shelf around islands seamounts. High concentration sets occurred throughout year Marías Cabo Corrientes, particularly in March June. A warm (>28ºC) coastal jet a width 1.5 Rossby radius (~20.6 km) was observed off...
Abstract In this study we investigate the reproductive dynamics of common dolphinfish (Coryphaena hippurus), using gonads obtained from four locations in Baja California Sur. From August 2004 to November 2006, 2839 were collected (1399 males and 1440 females), ranging size 42 155 cm fork length (FL). The sampling revealed a marked seasonality abundance with 65% samples summer–autumn. Histological analyses 320 (84 236 females) showed maximal activity during months increased abundance, which...
