Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

open access: yesIntegrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

open access: yesIntegrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

open access: yesIntegrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Analysis of repetitive DNA sequences in the sex chromosomes of Oreochromis niloticus [PDF]

open access: yes, 2003
In the Nile tilapia, Oreochromis niloticus, sex determination is primarily genetic, with XX females and XY males. While the X and Y chromosomes (the largest pair) cannot be distinguished in mitotic chromosome spreads, analysis of comparative ...

The growth performance and genotoxicity effect of dietary Aloe vera on Oreochromis niloticus juveniles

open access: yesAceh Journal of Animal Science, 2020
Growth and all activities of fish depend significantly on the food they consume.  However, with the rising price of conventional feedstuffs, there is a need to investigate less expensive and readily available plant source as an additive. This research is

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.
