Developmental RNA-Seq transcriptomics of haploid germ cells and spermatozoa uncovers novel pathways associated with teleost spermiogenesis
(Nature Research, 2022-08-19)
In non-mammalian vertebrates, the molecular mechanisms involved in the transformation of haploid germ cells (HGCs) into spermatozoa (spermiogenesis) are largely unknown. Here, we investigated this process ...
The gut microbiota of Cystidicola farionis parasitizing the swim bladder of the nosed charr morph Salvelinus malma complex in Lake Kronotskoe (Kamchatka, Russia)
(Society of Nematologists, 2021-12-15)
Using the approach of sequencing the V3–V4 region of the 16S rRNA gene, we have analyzed the bacterial diversity associated with the gut and “body” (other parts of nematode after dissection: cuticle, ...
Rapid detection of ciguatoxins in Gambierdiscus and Fukuyoa with immunosensing tools
(Elsevier, 2020-08-05)
Consumption of seafood contaminated with ciguatoxins (CTXs) leads to a foodborne disease known as ciguatera. Primary producers of CTXs are epibenthic dinoflagellates of the genera Gambierdiscus and ...
Lysine and methionine supplementation in high soy protein content diets for silvery-black porgy (Sparidentex hasta) juveniles
(Iranian Fisheries Science Research Institute, 2020-05-01)
A two-month feeding trial was conducted to evaluate the effect of partial replacement of fish meal (FM) by soybean protein (SP) alone or in combination with lysine (Lys) and methionine (Met) supplementation ...
Diet and other environmental factors shape the bacterial communities of fish gut in an eutrophic lake
(Wiley, 2018-08-09)
Aims
The aim of this work was to study the gut microbial diversity from eight species of wild fish with different feeding habits, digestive physiology (gastric vs agastric) and provide comparative ...
Physicochemical and Biochemical Properties of Trypsin-like Enzyme from Two Sturgeon Species
(MDPI, 2023-02-26)
This work aimed to determine the physicochemical and biochemical properties of trypsin from beluga Huso huso and sevruga Acipenser stellatus, two highly valuable sturgeon species. According to the results ...
Debaryomyces hansenii supplementation in low fish meal diets promotes growth, modulates microbiota and enhances intestinal condition in juvenile marine fish
(BMC, 2023-07-09)
Background
The development of a sustainable business model with social acceptance, makes necessary to develop new strategies to guarantee the growth, health, and well-being of farmed animals. Debaryomyces ...
The Lineage-Specific Evolution of Aquaporin Gene Clusters Facilitated Tetrapod Terrestrial Adaptation
(Public Library of Science, 2014-11-26)
A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant ...
Intraspecific structure of the Coregonus lavaretus complex in water bodies of Siberia: a case of postglacial allopatric origin of Yukagirian whitefish
(NRC Research (Canadian Science Publishing), 2021-11-05)
The results of morphological and genetic analyses of forms/species of the Coregonus lavaretus pidschian (Gmelin, 1789) complex from the Indigirka and Kolyma river basins are presented in the context of ...
Effect of short-term rotifer enrichment with marine phospholipids on growth, survival, and composition of meager (Argyrosomus regius) larvae
(Frontiers Media, 2020-12-09)
Larval rearing and ongrowing of meager have experienced a great advance during the last years and nowadays this species is considered as one of the most important new species in Mediterranean aquaculture. ...
