Using head, pectoral girdle bones and otoliths to estimate length and weight of Argentine anchovy (Engraulis anchoita), a key species in Patagonian marine ecosystem [PDF]

Marine and Fishery Sciences, 2023
The Argentine anchovy, Engraulis anchoita, plays a vital role as a key prey species for several marine predators in the north Patagonian marine ecosystem of the Atlantic Ocean.

Crecimiento y condición otoñal de larvas de anchoíta en la Zona Común de Pesca Argentino-Uruguaya [PDF]

Marine and Fishery Sciences, 2019
Se determinó el crecimiento y la condición nutricional de larvas de Engraulis anchoita en la Zona Común de Pesca Argentino-Uruguaya (ZCPAU). La condición se estimó a partir de la relación ARN/ADN estandarizada (RDs) del tronco muscular. El crecimiento se

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

Scientia 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.

The nutritional quality and contents of heavy elements due to thermal processing and storage in canned Thunnus tonggol fish change compared to fresh fish. [PDF]

Food Sci Nutr, 2023
The results of the statistical analysis of the samples showed that canning and sterilization by autoclave increased the contents of elements except mercury to a significant level (p < .05). The results showed that the amount of fat significantly increased in all samples after processing (p < .05), but the amount of ash and protein significantly ...

Molecular analyses of carangid fish diets reveal inter-predation, dietary overlap, and the importance of early life stages in trophic ecology. [PDF]

Ecol Evol
Metabarcoding of fish stomach contents is a modern approach that can help resolve marine food webs and assist in management of fisheries. Analysis of the diet of seven carangid fish species in the southwest Atlantic using this technique identified principal links that can influence the pelagic sardine fisheries. The contribution of early life stages of

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

Fish 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.

ARN/ADN e índices de condición derivados de larvas de anchoíta y merluza como información relevante para la gestión integral de las pesquerías [PDF]

, 2022
The nutritional condition of anchovy and Argentine hake larvae in the Northern Patagonian Frontal System (NPFS) area was studied in the austral spring of 2018. We hypothesized that this area provides adequate features for larval growth and survival.

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

Aquaculture, 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.
