Seasonal variations in the growth of anchovy larvae (Engraulis anchoita) on the Argentine coastal shelf

open access: yesScientia Marina, 2010
Age and growth rates of the anchovy larvae (Engraulis anchoita) in Argentine waters were estimated by analysing daily growth increments in sagittal otoliths under light microscope.

Analysis of the reproductive potential of two stocks of Engraulis anchoita in the Argentine Sea

open access: yesCiencias Marinas, 2011
Relative batch fecundity, spawning frequency, size at 50% maturity, sex ratio, and egg production were estimated for the Bonaerense and Patagonian Engraulis anchoita stocks.

Reproductive success of the Argentine anchovy, Engraulis anchoita, in relation to environmental variability at a mid‐shelf front (Southwestern Atlantic Ocean)

open access: yesFisheries Oceanography, 2013
The mid-shelf front (MSF) of the Buenos Aires province continental shelf in the Southwestern Atlantic Ocean plays a central role in the pelagic ecosystem of the region acting as the main spring reproductive area for the northern population of the ...

Trophic ecology of Patagonian flounder Paralichthys patagonicus (Jordan, 1889) in the Argentine-Uruguayan Coastal Ecosystem

open access: yesMarine and Fishery Sciences, 2021
Food habits and diet composition of Patagonian flounder Paralichthys patagonicus (Jordan, 1889) were studied on the basis of stomach content analyses from 828 specimens (512 females, 304 males, 12 unsexed) collected during 16 commercial cruises between ...

How consistent is the advice from stock assessments? Empirical estimates of inter‐assessment bias and uncertainty for marine fish and invertebrate stocks

open access: yesFish and Fisheries, Volume 24, Issue 1, Page 126-141, January 2023., 2023
Abstract Fishery management frequently involves precautionary buffering for scientific uncertainty. For example, a precautionary buffer that scales with scientific uncertainty is used to calculate the acceptable biological catch downward from the overfishing limit in the US federal fishery management system.

Effects of formalin preservation on egg size of small pelagic fish as major target species in ichthyoplankton surveys

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 3, Page 208-215, June 2022., 2022
Effects of formalin preservation on egg size for Japanese sardine Sardinops melanostictus, chub mackerel Scomber japonicus, and Japanese anchovy Engraulis japonicus over a long period (30 or 36 months). Overall, the egg sizes slightly decreased in a couple of months after preservation but then recovered to be at a similar level to the live eggs.

Temporal variations in hatch date and early survival of Japanese anchovy (Engraulis japonicus) in response to environmental factors in the central Seto Inland Sea, Japan

open access: yesFisheries Oceanography, Volume 30, Issue 5, Page 527-541, September 2021., 2021
Abstract Reproductive success can be influenced by the match or mismatch between the spawning season and optimal environmental conditions for larval survival. However, it is challenging to understand how temporal factors affect population dynamics.
