Detection of isothermally amplified ostreid herpesvirus 1 DNA in Pacific oyster (Crassostrea gigas) using a miniaturised electrochemical biosensor
(Elsevier, 2019-09-02)
Given the threat that ostreid herpesvirus 1 (OsHV-1) poses to shellfish aquaculture, the need for rapid, user-friendly and cost-effective methods to detect this marine pathogen and minimise its impact ...
Digestive enzyme activities during pejerrey (Odontesthes bonariensis) ontogeny
(Elsevier, 2020-02-22)
The first step for assessing and refining the nutritional requirements during the larval and early juvenile stages of a fish is the study of the ontogeny of digestive system functionality. The combination ...
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 ...
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 ...
A re-evaluation of conflicting taxonomic structures of Eurasian Triaenophorus spp. (Cestoda, Bothriocephalidea: Triaenophoridae) based on partial cox1 mtDNA and 28S rRNA gene sequences
(Canadian Science Publishing, 2022-07-13)
Cestodes of the genus Triaenophorus Rudolphi, 1793 are widely distributed parasites of Esocidae, Percidae, Salmonidae, Thimallidae, Cobitidae, Osmeridae, Cyprinidae, Cottiidae, Lotidae, and several ...
Vibrio eleionomae sp. nov., isolated from shrimp (Penaeus vannamei) pond water
(Microbiology Society, 2023-05-11)
A novel Vibrio strain (CAIM 722T=SW9T=DSM 24596T) was isolated in 2003 from water of a shrimp (Penaeus vannamei) culture pond located in Los Mochis, Sinaloa, Mexico, and taxonomically characterized using ...
Towards the standardization of brush border purification and intestinal alkaline phosphatase quantification in fish with notes on other digestive enzymes
(Elsevier, 2018-01-06)
Assessing the activity of digestive enzymes is a common procedure in many biological, physiological and nutritional studies. After reviewing the available literature on fish digestive tract maturation ...
