The effect of diet on the structure of gut bacterial community of sympatric pair of whitefishes (Coregonus lavaretus): one story more
(PeerJ, 2019-12-03)
In the Coregonus lavaretus complex may be found lacustrine sympatric pairs, which serves as an intriguing model for studying different aspects of fish evolutionary biology. One such sympatric whitefish ...
Zebrafish as a Model to Screen the Potential of Fatty Acids in Reproduction
(Mary Ann Liebert, 2019-01-31)
Sperm quality is an important topic in general health, chemotherapy, and gamete preservation technology. Fatty acid (FA) composition of membranes, which is influenced by the diet, plays key roles in ...
Breeding, planktonic and settlement factors shape recruitment patterns of one of the last remaining major population of Pinna nobilis within Spanish waters
(Springer, 2019-11-27)
The pen shell, Pinna nobilis L., is a critically endangered bivalve threatened by mass mortality events throughout the Mediterranean, but the Alfacs Bay (Ebro Delta) still hosts many healthy individuals. ...
Dynamics of the Pacific Oyster Pathobiota during mortality episodes in Europe assessed by 16S rRNA gene profiling and a new target enrichment next‐generation sequencing strategy
(Wiley, 2019-07-20)
Infectious agents such as the bacteria Vibrio aestuarianus or Ostreid herpesvirus 1 (OsHV‐1) have been repeatedly associated with dramatic disease outbreaks of Crassostrea gigas beds in Europe. Beside ...
Gene expression analysis of the innate immune system during early rearing and weaning of meagre (Argyrosomus regius)
(Elsevier, 2019-10-06)
The present study is the first report of some representative innate immune genes in meagre (Argyrosomus regius) larvae. This study has specifically focused on the growth period from hatching to the ...
The impacts of ostreid herpesvirus 1 microvariants on Pacific oyster aquaculture in the Northern and Southern Hemispheres since 2008
(Office International des Épizooties (OIE), 2019-09-01)
Mollusc farming is the third most productive aquaculture activity in the world, and the Pacific oyster (Crassostrea gigas) is one of the most important farmed species. Since 2008, mass mortalities in ...
Composition of the microbial communities in the gastrointestinal tract of perch (Perca fluviatilis L. 1758) and cestodes parasitizing the perch digestive tract
(Wiley, 2019-10-29)
Using the approach of sequencing the V3‐V4 region of the 16S rRNA gene, we have analysed the bacterial diversity associated with the distinct compartments of the gastrointestinal tract of perch (Perca ...
Sperm contamination by urine in Senegalese sole (Solea senegalensis) and the use of extender solutions for short-term chilled storage
(Elsevier, 2019-11-01)
Methods are needed to manage the sperm of Senegalese sole (Solea senegalensis), which will enable the industry to use artificial fertilisation to reproduce hatchery raised sole and implement breeding ...
Linking stocking densities and feeding strategies with social and individual stress responses on gilthead seabream (Sparus aurata)
(Elsevier, 2019-10-24)
Intensive aquaculture and poor management practices can cause stress and compromise welfare of farmed fish. This study aimed to assess the potential links between stocking densities and feeding methods ...
Ontogeny of the digestive enzyme activity of the Amazonian pimelodid catfish Pseudoplatystoma punctifer (Castelnau, 1855)
(Elsevier, 2019-01-30)
The aim of the study was to evaluate the functional ontogeny of the digestive system of Pseudoplatystoma punctifer through the analysis of the activity of the main intestinal (alkaline phosphatase, ...
