Spawning, daily egg production, and spawning stock biomass estimation for common sardine (Strangomera bentincki) and anchovy (Engraulis ringens) off central southern Chile in 2002
Abstract In this paper, the first daily egg production method (DEPM) parameters were estimated for anchovy and common sardine stocks distributed in the central-south area off Chile (33–40°S). TheExpand

Is the spawning frequency dependent on female size? Empirical evidence in Sardinops sagax and Engraulis ringens off northern Chile
In this study, we review the relationship between female size and spawning frequency using information from Sardinops sagax and Engraulis ringens, two species which are important for the economy ofExpand

Egg trait variation in anchoveta Engraulis ringens: a maternal response to changing environmental conditions in contrasting spawning habitats
The Engraulis ringens distribution (4 to 42° S) covers a wide variety of environmental conditions. We assessed the coping mechanisms used by this anchoveta in different spawning habi- tats, reportingExpand

Variability in oocyte size and batch fecundity in anchoveta (Engraulis ringens, Jenyns 1842) from two spawning areas off the Chilean coast
Utilising histological preparations of ovaries from Engraulis ringens females collected in two contrasting spawning habitats along the Chilean coast, we assess the variability in oocyte size andExpand

Biochemical composition of seston in two upwelling sites within the Humboldt Current System (21°S to 23°S): Summer conditions
Abstract The biochemical composition of seston within the Humboldt Current System (HCS) in two bays off northern Chile (21°S–23°S) was assessed to estimate its chemical quality as potential foodExpand
