Erroneous identification of the mussel, Mytilus galloprovincialis (Lamarck 1819) as the specie, Mytilus chilensis (Hupe 1854) in the Bay of Concepcion, Chile
Esta comunicacion informa que la presencia de Mytilus chilensis (Hupe 1854) citada en la literatura cientifica para la costa de la Bahia de Concepcion (Chile) no es correcta, siendo Mytilus
Latitudinal and seasonal egg-size variation of the anchoveta (Engraulis ringens) off the Chilean coast
TLDR
Changes in egg size throughout the anchoveta spawning season as well as for the peak months of the spawning season are reported and whether differences in larval length and yolksac volume occur in hatching larvae are evaluated.
Fatty acids in eggs of anchoveta Engraulis ringens during two contrasting winter spawning seasons
TLDR
The results suggest that the higher PUFA and lower DHA/EPA values for anchoveta eggs in 2007 may have resulted from increased consumption of larger herbivorous copepods or direct consumption of large phytoplankton, prey typical of cold upwelling conditions.
Food size selectivity and diet overlap in larvae of Clupeiform species from central Chile
TLDR
Le regime alimentaire des larves de quatre especes de Clupeiformes (Sardinops sagax, Strangomera bentincki, Ethmidium maculatum et Engraulis ringens) a ete etudie au cours des mois de septembre et novembre dans la Baie de Concepcion, Chili central.
Egg trait variation in anchoveta Engraulis ringens: a maternal response to changing environmental conditions in contrasting spawning habitats
TLDR
These egg characteristics are determined by the adult female reproductive system, representing a maternal influence on the early life-history traits of anchoveta that might enable rapid changes in population densities in some years of improved habitat conditions.
Inter-population differences in temperature effects on Engraulis ringens yolk-sac larvae
TLDR
The results suggest that anchoveta populations from Talcahuano compensate for their lower larval growth rates by increasing their initial egg and hatch sizes, as they are larger than Antofagasta larvae at the end of the yolk-sacstage, which is typical of the Anchoveta southern spawning area.
Malformations in the embryonic development of Engraulis ringens (Clupeiformes) in a spawning area off central–southern Chile: description and rates
TLDR
A relationship between egg size and malformation rates was detected among the samples from each sampling date, which suggests that malformations may be attributable to endogenous factors rather than to environmental factors acting directly on the eggs in the plankton.
A New Developmental Toxicity Test for Pelagic Fish Using Anchoveta (Engraulis ringens J.)
TLDR
The results demonstrated that the protocol and handling procedures implemented for the anchoveta embryo bioassays comply with international standards for intra-laboratory precision.
