The 2021 summer upwelling season off the United States Pacific Northwest coast was unusually strong leading to widespread near-bottom, low-oxygen waters. During 2021, an unprecedented number of ship- and underwater glider-based measurements dissolved oxygen were made in this region. Near-bottom hypoxia, that is less than 61 µmol kg
Abstract In August 2007, as part of the NOAA National Marine Fisheries Service (NMFS) West Coast Groundfish Bottom Trawl Survey, we examined biomass demersal organisms in a known hypoxic area off Oregon coast. Although observed each summer, intensity hypoxia has varied annually (2002–2007) with greatest temporal and spatial extent noted 2006. 2007 identified geographic zone sampled 17 stations along two depth contours (50 70 m) within area. A Sea‐Bird SBE 19 plus equipped dissolved oxygen...
Abstract Various ocean‐climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen ( DO ) as result of greater stratification, reduced ventilation below the thermocline, decreased solubility at temperatures. Since spreading low waters is underway predicted to increase, understanding impacts on trophic levels essential. Within California Current System, shoaling minimum zone OMZ expected produce complex changes. Onshore movement...
Fish reproductive patterns are very diverse in terms of breeding frequency, mating system, sexual dimorphisms and selection, mate choice, spawning site courtship patterns, behaviors parental care. Here we have compared the behavior surface-dwelling cave-dwelling morphs characiform A. mexicanus, with goals documenting this emerging model organism, its possible evolution after cave colonization, sensory modalities involved. Using infrared video recordings, showed that surface Astyanax is...
Abstract Infrared (IR) light is widely accepted as a non‐intrusive lighting for discreet observation but relevant studies are scarce. The response of European seabass Dicentrarchus labrax (Linnaeus 1758) towards IR was tested during laboratory experiments alternating sequences and dark conditions. Swimming trajectories were extracted from hydroacoustic videos behavioural metrics (e.g. speed, bearings) quantified the D. movement patterns. showed no preference nor deterrence light, supporting...
Life in the darkness of caves is accompanied, throughout phyla, by striking phenotypic changes including loss or severe reduction eyes and pigmentation. On other hand, cave animals have undergone constructive changes, thought to be adaptive, survive this extreme environment. The present study addresses question evolution growth caves, taking advantage comparison between river-dwelling cave-dwelling morphs Mexican tetra, Astyanax mexicanus. A sclerochronology approach was undertaken document...
The use of microalgae as a sustainable source n-3 long-chain polyunsaturated fatty acids (LC-PUFA) an alternative to fish oils from small pelagic (e.g., anchovy, sardine) has received growing interest in the past few years. present study aimed to: (i) produce Aurantiochytrium mangrovei biomass by heterotrophic fermentation using medium containing anaerobic digestion liquid effluent, and (ii) evaluate rich LC-PUFA good quality proteins feed ingredient for sea bass juveniles larvae. Two 800 L...
Some have suggested that targeting conservation efforts on biodiversity hotspots—areas of exceptionally high diversity—is the most efficient way to use limited resources protect or rarest species. Moreover, preservation is a focus for resource management and because links between ecosystem function. However, there are many ways define plethora diversity indices. Do these indices agree where hotspots are, by extension, should take place? Here we habitat modeling approach map spatial temporal...
The morphogenesis of the vertebrate eye consists a complex choreography cell movements, tightly coupled to axial regionalization and type specification processes. Disturbances in these events can lead developmental defects blindness. Here, we have deciphered sequence defective leading coloboma embryonic blind cavefish species Astyanax mexicanus. Using comparative live imaging on targeted enhancer-trap Zic1:hsp70:GFP reporter lines both normal, river-dwelling morph cave species, identified...

The incubation of eggs on pleopods 13 female noble crayfish was controlled by means water temperature after CUKERZIS et al. (1978). Out-door 15 females monitored at ambient in an earthen storage pond. With eggs, the duration period shortened and earlier hatching resulted so-called advanced juveniles. They hatched 88 days than those normally during out-door egg incubation. These prolonged rearing juvenile 1st growing season. When were isolated, there a significantly lower number stage 2...
Cowcod (Sebastes levis) is a member of northeastern Pacific Ocean species flock that experienced extensive fishery exploitation. Factors could produce structure in cowcod include major biogeographic boundary within cowcod’s geographical distribution; severe declines abundance, potentially, resulting reductions effective population size and divergence owing to genetic drift; dependence on patchily distributed habitat. We examine the following two questions: (i) there subdivision present and,...

The mechanisms behind the beneficial effects of dietary peptides on fish skeletal development remain unrevealed. In present study, we evaluated effect 0% (C, Control), 6% (P6) and 12% (P12) levels small peptide incorporation European sea bass (Dicentrarchus labrax) early larval post-larval integrity against a swimming challenge test. Survival was not affected by diets, whereas P6 presented lowest growth rate. Larval quality control underlined advantageous P12 reducing frequency cephalic...
