Transgenerational Heat Exposure Triggers Unexpected Compensatory Sex Ratio Responses in a Temperature-Sensitive Fish Under Climate Warming. [PDF]

Glob Chang Biol
Rising temperatures can unbalance the number of males and females in species whose sex is influenced by the environment. In a decade‐long experiment with European sea bass, we found that heat during development produces more males, but the thermal history of parents—especially fathers—can unexpectedly push offspring sex ratios back in the opposite ...

<i>Lactobacillus</i>-Derived Biosurfactants: Emulsification and Antioxidant Properties in Oil Emulsions. [PDF]

Food Sci Nutr
Extracted biosurfactants from lactobacilli present in traditional yogurt had emulsifying performance in emulsions. Oxidation levels indicated that the emulsions prepared with biosurfactants were significantly less oxidized compared to the control sample. This research introduces the biosurfactants derived from L. plantarum and L.

The cellular basis of compensatory muscle growth in the teleostOdontesthes bonariensis

Journal of Experimental Biology, 2022
ABSTRACTThis study evaluates white muscle growth and in vivo cell proliferation during a fasting and refeeding trial, using pejerrey (Odontesthes bonariensis) as animal model, in order to better understand the cellular basis governing catch-up growth. Experiments consisted of two groups of fish, a control group continuously fed ad libitum, and a group ...

Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture. [PDF]

Aquac Nutr
Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural

Occurrence and control of Chilodonella spp. in pejerrey Odontesthes bonariensis [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2011
O presente trabalho teve por objetivo relatar a ocorrência e controle de infecção parasitária por Chilodonella spp. em alevinos de peixe-rei (O. bonariensis). A Chilodonella spp. é um ciliado que parasita tegumento e brânquias de peixes, podendo ocasionar grande mortalidade.

Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data. [PDF]

Cladistics
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.

Molecular parallelism in the evolution of a master sex‐determining role for the anti‐Mullerian hormone receptor 2 gene (amhr2) in Midas cichlids

Molecular Ecology, Volume 32, Issue 6, Page 1398-1410, March 2023., 2023
Abstract The evolution of sex chromosomes and their differentiation from autosomes is a major event during genome evolution that happened many times in several lineages. The repeated evolution and lability of sex‐determination mechanisms in fishes makes this a well‐suited system to test for general patterns in evolution.

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

Reviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from
