Hydromechanics of swimming propulsion. Part 3. Swimming and optimum movements of slender fish with side fins [PDF]

, 1971
This paper seeks to evaluate the swimming flow around a typical slender fish whose transverse cross-section to the rear of its maximum span section is of a lenticular shape with pointed edges, such as those of spiny fins, so that these side edges are ...

Cytological analysis of integumentary and muscular adaptations in three sand‐dwelling marine teleosts, Ammodytes tobianus (Ammodytidae), Gorgasia preclara (Congridae) and Heteroconger hassi (Congridae) (Teleostei; Actinopterygii)

Journal of Fish Biology, Volume 97, Issue 4, Page 1097-1112, October 2020., 2020
Abstract Sandy bottoms are a ubiquitous environment found from sea bottoms to intertidal and freshwater zones. They are inhabited by many invertebrates and vertebrates which have developed morphological and physiological adaptations to sustain life under these particular conditions.

Differential expression and novel permeability properties of three aquaporin 8 paralogs from seawater-challenged Atlantic salmon smolts [PDF]

, 2013
Summary Aquaporins may facilitate transepithelial water absorption in the intestine of seawater (SW) acclimated fish. Here we have characterized three full-length aqp8 paralogs from Atlantic salmon (Salmo salar).

Biodiversity, Systematics, and Taxonomy of Ostariophysi (Osteichthyes, Actinopterygii): What We Know Today After Three Decades of Integration of Morphological and Molecular Data

Taxonomy
Ostariophysi is the second largest superorder of fishes, formed almost exclusively by freshwater species, with 102 families, 1372 genera, and 11,883 species, thus containing approximately 30% of the known fish species in the world and almost 70% of the ...

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 ...

A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage

Journal of Fish Biology, EarlyView.
Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.
