Salt Sensitive Tet-Off-Like Systems to Knockdown Primordial Germ Cell Genes for Repressible Transgenic Sterilization in Channel Catfish, Ictalurus punctatus

Marine Drugs, 2017
Repressible knockdown approaches were investigated for transgenic sterilization in channel catfish, Ictalurus punctatus. Two primordial germ cell (PGC) marker genes, nanos and dead end, were targeted for knockdown, and an off-target gene, vasa, was ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Which attributes of restored oyster reefs provide the best habitat for sportfish?

Restoration Ecology, EarlyView.
Abstract Introduction Restoration practitioners seek to restore oyster ecosystems as habitat designed for species targeted by recreational fisheries, but they require information on which specific habitat parameters of oyster reefs are preferred by fish.

Beyond barriers: fish assemblage recovery following dam removal on the Cuyahoga River, a Lake Erie tributary

Restoration Ecology, EarlyView.
Dam removals are increasing globally, yet ecological outcomes vary widely because biological recovery depends on post‐removal connectivity and access to source populations. We evaluated how multiple dam removals and remaining fragmentation influenced fish assemblage recovery in the Cuyahoga River (OH, United States), a historically polluted Great Lakes

Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.
