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 ...
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 ...
No hybridization and marked interspecific differences in individual growth rate in mixed cultures of Manila clam (Ruditapes philippinarum) and grooved carpet-shell clam (R. decussatus)
(Elsevier, 2021-04-24)
The Manila clam (Ruditapes philippinarum) was introduced in Europe in the 1970's and in the following years it became naturalized. Interactions with the native species include hybridization with the ...
Diet, Immunity, and Microbiota Interactions: An Integrative Analysis of the Intestine Transcriptional Response and Microbiota Modulation in Gilthead Seabream (Sparus aurata) Fed an Essential Oils-Based Functional Diet
(Frontiers Media, 2021-03-04)
Essential oils (EOs) are promising alternatives to chemotherapeutics in animal production due to their immunostimulant, antimicrobial, and antioxidant properties, without associated environmental or ...
The feasibility of using gas mixture to stun seabream (Sparus aurata) before slaughtering in aquaculture production
(Elsevier, 2021-07-10)
Current European Union regulation explicitly states that farmed fish should be spared any avoidable pain, distress or suffering at the time of slaughter. It has been shown that fish suffer when they are ...
Effects of Dietary Lipid Levels on Growth and Gonad Development of Onychostoma macrolepis Broodfish
(MDPI, 2022-10-18)
To assess the lipid requirements of O. macrolepis broodstock, five iso-nitrogenous diets (39 g kg−1) with five lipid levels, 50 (5 L), 70 (7 L), 90 (9 L),110 (11 L), and 130 (13 L; g kg−1), were made. ...
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 ...
Improving pikeperch larviculture by combining environmental, feeding and populational factors
(Elsevier, 2020-05-12)
Pikeperch (Sander lucioperca) has a high potential for inland aquaculture diversification in Europe. Bottlenecks (i.e. low survival, cannibalism and deformity rates) hamper further expansion of pikeperch ...
Growth performance of gilthead sea bream (Sparus aurata) fed a mixture of single cell ingredients for organic diets
(Elsevier, 2024-04-22)
The aim of this study was to investigate the growth performance of gilthead sea bream (Sparus aurata) fed with a mixture of a single cell ingredient (SCI) (bacterial protein, yeast protein and algae) ...
Dependence of element composition of bile of freshwater and marine fishes on some abiotic and biotic factors
(Frontiers, 2023-10-18)
Introduction: The elemental composition and physical properties of fish bile is a very important marker for ecotoxicological and physiological studies as bile is able to accumulate elements from ...
