Revisiting the History of Ornamental Aquaculture in Europe to Understand the Benefits and Drawbacks of Freshwater Fish Imports

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT Ornamental aquaculture and fishkeeping are very popular with millions of enthusiasts worldwide. The number of newly imported fish species for ornamental purposes grew slowly from World War I until the 1980s. It then exponentially increased until now with more than 7900 species and a large number of scientifically undescribed morphotypes.

Host Specificity of Calyptospora funduli (Apicomplexa: Calyptosporidae) in Atheriniform Fishes

The Journal of Parasitology, 1993
Calyptospora funduli has a broad host specificity, infecting at least 7 natural and 10 additional experimental definitive hosts, all atheriniform fishes within 5 families, but most in the genus Fundulus. Barriers, apparently innate ones, prevent any development of C.

eDNA Metabarcoding Analysis of Bony Fish Identification in Coastal Water of Gulf of Maine Using Nested Polymerase Chain Reaction of 12S rRNA Universal Primers

Environmental DNA, Volume 6, Issue 6, November–December 2024.
ABSTRACT Ecosystems in coastal waters of Gulf of Maine (GOM) are undergoing environmental challenges in response to climate change and anthropogenic stressors. eDNA metabarcoding, a powerful tool for assessing the fish community structure, was used to identify fish communities in three types of GOM aquatic environments (sand, macroalgae, and eelgrass ...

DNA metabarcoding unveils multiscale trophic variation in a widespread coastal opportunist

Molecular Ecology, Volume 28, Issue 2, Page 232-249, January 2019., 2019
Abstract A thorough understanding of ecological networks relies on comprehensive information on trophic relationships among species. Since unpicking the diet of many organisms is unattainable using traditional morphology‐based approaches, the application of high‐throughput sequencing methods represents a rapid and powerful way forward.

Influence of body weight/age on the food intake, growth and conversion efficiency of Gambusia affinis [PDF]

, 1977
On a restricted food supply of Tubifex tubifex (2h/day) the fish consumed only 69.5 mg dry food/g live fish/day and grew only to 25.6 mg live body weight by the 30th day of it's age, while those fed ad libitum consumed 94.7 mg/g/day and attained a body ...

Salinity plays a limited role in determining rates of size evolution in fishes globally across multiple scales

Global Ecology and Biogeography, Volume 33, Issue 9, September 2024.
Abstract Aim Substantial progress has been made to map biodiversity and its drivers across the planet at multiple scales, yet studies that quantify the evolutionary processes that underpin this biodiversity, and test their drivers at multiple scales, are comparatively rare.
