Ontogeny of the digestive enzyme activity of the Amazonian pimelodid catfish Pseudoplatystoma punctifer (Castelnau, 1855)
(Aquaculture, 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, aminopeptidase N, maltase ...
Lecithin-enriched Artemia combined with inert diet and its effects on reproduction and digestive enzymes of Aequidens rivulatus
(Aquaculture, 2019-06-27)
The present study investigated the effects of soybean lecithin bioencapsulated in adult Artemia franciscana and unenriched Artemia in combination with an inert diet on digestive enzymes activity and reproductive performance ...
Detection of isothermally amplified ostreid herpesvirus 1 DNA in Pacific oyster (Crassostrea gigas) using a miniaturised electrochemical biosensor
(Talanta, 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 is evident. In this ...
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
(Environmental Microbiology, 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 roles played by these ...
Gene expression analysis of the innate immune system during early rearing and weaning of meagre (Argyrosomus regius)
(Fish and Shellfish Immunology, 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 juvenile stage, a critical ...
Fast analysis of relevant contaminants mixture in commercial shellfish
(Talanta, 2019-05-04)
One of the major challenges currently faced is to develop systematic ways of addressing chemical mixtures in environmental assessment. With this purpose, a simple, rapid, and sensitive method for the detection and ...
Effects of soy protein base diet supplemented with lysine and methionine on digestive enzymes activity and hematological parameters in silvery-black porgy (Sparidentex hasta) juveniles
(Iranian Journal of Fisheries Sciences, 2019-03-06)
The effect of dietary partial replacement of fish meal (FM) by soybean protein (SP) alone or in combination with lysine (Lys) and methionine (Met) supplementation were tested in a 60-days feeding trial for silvery-black ...
Composition of the microbial communities in the gastrointestinal tract of perch (Perca fluviatilis L. 1758) and cestodes parasitizing the perch digestive tract
(Journal of Fish Diseases, 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 fluviatilis) and ...
Linking stocking densities and feeding strategies with social and individual stress responses on gilthead seabream (Sparus aurata)
(Physiology and Behavior, 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 with social and ...
Effects of taurine supplementation in soy-based diets on growth performance and fillet quality in European sea bass (Dicentrarchus labrax)
(Aquaculture, 2019-11-01)
This study evaluated the effects of taurine supplementation to diets containing a high dietary inclusion of soybean meal and soy protein concentrate on growth performance and fillet quality of juvenile European sea bass ...
