Spawning of the southern hake Merluccius australis (Pisces: Merlucciidae) in Chilean fjords
Large patches of eggs with undeveloped embryos, eggs in late development and abundant southern hake larvae were observed inside Chilean fjords during austral spring season, and inter-annual variability in egg size was detected, despite the relatively constant seawater temperature.
Effects of temperature and lipid droplet adherence on mortality of hatchery-reared southern hake Merluccius australis larvae
This study provides the first data on the influence of the lipid droplet absorption on larval survival of cultured hake, and can be used as an early indication of the quality of the batch.
Distribution of carnivorous gelatinous zooplankton in the upwelling zone off central Chile (austral spring 2001)
The most abundant species occurred more frequently inwell-oxygenated waters; however, high abundances (10–100 ind. 100 m) nearshore, characteristics of upwelling conditions in eastern boundary regions, occurred throughout the cruise.
Larval distribution and growth of the rockfish, Sebastes capensis (Sebastidae, Pisces), in the fjords of southern Chile
Ontogenetic differences in distributions suggest that different habitats are utilized during the early life stages of S. capensis, and that they seem to be shared with several other Sebastes species, however, the mechanisms for transport in different areas vary widely, making the question of the evolutionary forces driving these ontogenetic changes in distribution even more intriguing.
Spring spawning and early nursery zone of the mesopelagic fish Maurolicus parvipinnis at the coastal upwelling zone off Talcahuano, central Chile
Coastal upwelling areas along eastern boundary currents have been recognized for having high planktonic production. In the Humboldt Current System off South America, little is known about the
Seasonal and annual variation in Chilean hake Merluccius gayi spawning locations and egg size off central Chile
Recent variations in Chilean hake reproductive tactics may reflect an indirect effect of declines in the parental population size, coinciding with variations in spawning locations (more coastward in early spring 2004 and 2005) and decline in egg size.
Spawning and early nursery areas of anchoveta Engraulis ringens Jenyns, 1842 in fjords of southern Chile
The spatial and temporal variability in the spawning of E. ringens in the fjord region of southern Chile between 1995 and 2005 was analysed and showed an increase in the mean abundance of anchoveta eggs, varying from mean values during October 1995 to >14,000 eggs per 10 m2 during November 2005.
Larval fish distribution, growth and feeding in Patagonian fjords: potential effects of freshwater discharge
Gut content analysis showed that large larvae collected near sources of freshwater had lower number of prey in its guts and preyed on different items than fish larvae collected in saltier waters, therefore, freshwater inputs from rivers and glaciers from Patagonia affected horizontal distribution, recent growth and feeding of larval fish in fjords and channels of southern Chile.
The effects of a parasitic copepod on the recent larval growth of a fish inhabiting rocky coasts
The infestation of pennellids on coastal fish larvae may induce an increase in the pelagic larval duration and potentially affect the settlement rates of this intertidal fish.
Effects of salinity gradients on larval growth and otolith asymmetry of austral hake Merluccius australis
Larval M. australis were larger-at-age, grew faster and showed more asymmetry in areas with more influence of freshwater runoff in south Pacific Patagonia, and positive and significant correlations with vertical salinity gradients showed.
