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 ...
Mating behaviour and gamete release in gilthead seabream (Sparus aurata, Linnaeus 1758) held in captivity
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2015-02-11)
The present study aimed to describe the reproductive behaviour of gilthead seabream (Sparus aurata) in captivity. Twenty-four mature gilthead seabream, divided in two tanks, were utilized for the present ...
Meta‐analysis approach to the effects of live prey on the growth of Octopus vulgaris paralarvae under culture conditions
(Wiley, 2016-02-14)
The common octopus (Octopus vulgaris, Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during the first life stage is the main bottleneck for its commercial ...
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 ...
The Use of a DNA-Intercalating Dye for Quantitative Detection of Viable Arcobacter spp. Cells (v-qPCR) in Shellfish
(Frontiers, 2019-02-28)
The genus Arcobacter (Vandamme et al., 1991), comprised of Campylobacter-related species, are considered zoonotic emergent pathogens. The presence of Arcobacter in food products like shellfish, has an ...
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 ...
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. ...
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 ...
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 ...
