Evidence of dispersal between the Yenisei and the Lena river basins during the late Pleistocene within the whitefish (Coregonus lavaretus pidschian) complex
(NRC Research Press (Canadian Science Publishing), 2021-11-05)
The Coregonus lavaretus (Linnaeus, 1758) complex is a morphologically and genetically diverse group of whitefish. Its taxonomic structure has been controversial for almost a century. At least 25 forms ...
Isolation, identification, and gene expression analysis of the main digestive enzymes during ontogeny of the Neotropical catfish Pseudoplatystoma punctifer (Castelnau, 1855)
(Elsevier, 2021-06-09)
The ontogeny of the digestive capacities in fish is species-specific and its knowledge is essential for understanding the nutritional requirements of fish larvae. While the Amazon basin contains the ...
High genetic variability of Alexandrium catenella directly detected in environmental samples from the Southern Austral Ecosystem of Chile
(Elsevier, 2017-12-21)
Chilean waters are often affected by Alexandrium catenella, one of the leading organisms behind Harmful Algae Blooms (HABs). Genetic variability for this species are commonly carried out from cultured ...
Temperature effects on the growth and survival of tdh positive Vibrio parahaemolyticus in tissues of postharvest Manila clam (Ruditapes philippinarum)
(Elsevier, 2017-10-31)
Bivalve storage at inadequate temperatures contains greater densities of Vibrio parahaemolyticus. The objective of the present study was to determine if there were any differences in growth and survival ...
Presence of Vibrio mediterranei associated to major mortality in stabled individuals of Pinna nobilis L.
(Elsevier, 2019-12-20)
A major epizootic event attributed to Haplosporidium pinnae leading to 100% mortality of Pinna nobilis L. populations along Mediterranean coastlines started in the fall of 2016. As a result, a project ...
Reproductive success of a marine teleost was correlated with proactive and reactive stress‐coping styles
(Wiley, 2019-01-23)
The present study investigated the relationship between reproductive success and stress‐coping styles in gilthead seabream Sparus aurata in captivity. To characterise stress‐coping styles, a total of ...
Physiological processes modulate acute and chronic responses to dietary protein/energy ratio fluctuations in individuals and families of Manila clam (Ruditapes philippinarum) selected for variable growth rates
(Elsevier, 2020-01-31)
A range of phenotypes differing in growth rate were designed in the Manila clam by combining separate breeding families with size segregation within each family to constitute fast and slow growing groups. ...
Effects of rearing density on growth, digestive conditions, welfare indicators and gut bacterial community of gilthead sea bream (Sparus aurata, L. 1758) fed different fishmeal and fish oil dietary levels
(Elsevier, 2019-12-13)
In Mediterranean aquaculture, significant advances have been made towards a reduction of marine-derived ingredients in aquafeed formulation, as well as in defining the effect on how environmental factors ...
Ontogeny of lymphoid organs and mucosal associated lymphoid tissues in meagre (Argyrosomus regius)
(Elsevier, 2018-09-15)
This study investigates the development of lymphoid organs and mucosal tissues in larval and juvenile meagre, Argyrosomus regius. For this purpose, meagre larvae were reared from hatch to the juvenile ...
Emergence and clonal expansion of Vibrio aestuarianus lineages pathogenic for oysters in Europe
(Wiley, 2023-03-01)
Crassostrea gigas oysters represent a significant global food source with 4.7 million tons harvested per year. In 2001, the bacterium Vibrio aestuarianus subsp. francensis emerged as a pathogen that ...
