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

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 1: ToRs1-3. [PDF]

EFSA J
Abstract Surveillance data published since 2010, although limited, showed that there is no evidence of zoonotic parasite infection in market quality Atlantic salmon, marine rainbow trout, gilthead seabream, turbot, meagre, Atlantic halibut, common carp and European catfish.

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.

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.

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

Fisheries 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.

High inter‐ and intraspecific niche overlap among three sympatrically breeding, closely related seabird species: Generalist foraging as an adaptation to a highly variable environment?

Journal of Animal Ecology, Volume 89, Issue 1, Page 104-119, January 2020., 2020
This article shows a striking case of closely related and sympatrically breeding species overlapping in their resource use across multiple dimensions. The very unusual results are best explained by high food availability in combination with spatio‐temporal environmental variability and mobile prey fields, requiring predators to respond ...

Sex‐biased survival contributes to population decline in a long‐lived seabird, the Magellanic Penguin

Ecological Applications, Volume 29, Issue 1, January 2019., 2019
Abstract We developed a Hidden Markov mark–recapture model (R package marked) to examine sex‐specific demography in Magellanic Penguins (Spheniscus magellanicus). Our model was based on 33 yr of resightings at Punta Tombo, Argentina, where we banded ~44,000 chicks from 1983 to 2010.

Histological Features of the Gastrointestinal Tract of Wild Indonesian Shortfin Eel, Anguilla bicolor bicolor (McClelland, 1844), Captured in Peninsular Malaysia

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
This study was conducted to record the histological features of the gastrointestinal tract of wild Indonesian shortfin eel, Anguilla bicolor bicolor (McClelland, 1844), captured in Peninsular Malaysia. The gastrointestinal tract was segmented into the oesophagus, stomach, and intestine.

Comparative Histomorphological and Histochemical Studies on the Oesophagus of Nile Tilapia Oreochromis niloticus and African Catfish Clarias gariepinus

Journal of Histology, Volume 2014, Issue 1, 2014., 2014
The present work aimed to describe and compare both gross and microscopic structure of the oesophagus of Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus). For this purpose, 60 specimens of oesophagus of Nile tilapia (omnivorous fish) and African catfish (carnivorous fish) were collected and processed.
