Development of species identification techniques for anguillid eels using species-specific genetic markers

Frontiers in Marine Science
The decline in eel resources, coupled with the challenges of morphological identification and the rise of illegal trade, highlights the urgent need for accurate species identification techniques.

Differences in the eel peripheral blood hematologic parameters associated with papilloma (Papillomatosis anguillarum) [PDF]

Acta Ichthyologica et Piscatoria, 1974
As a result of studies on the eel (Anguilla anguilla L.) hematologic parameters, certain characteristic symptoms typical of the "cauliflower disease" (Papillomatosis anguillarum) have been established, both the different stages in ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

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

Integrative 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

Integrative 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 ...

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

Fisheries 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.

Linking foraging and breeding strategies in tropical seabirds

Journal of Avian Biology, 2021
The archetypal foraging behaviour of tropical seabirds is generally accepted to differ from that of their temperate and polar breeding counterparts, with the former exhibiting less predictable foraging behaviour associated with the less predictable prey ...

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

Fisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

Morphological, anatomical and histological studies on the olfactory organs and eyes of teleost fish: Anguilla anguilla in relation to its feeding habits

Journal of Basic and Applied Zoology, 2013
The morphology, anatomy and histology of the olfactory organ of Anguilla anguilla have been described. It was found that each olfactory chamber opens externally by an anterior inlet and posterior outlet nostrils.
