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.

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

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 ...

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.

Experimental Channel Catfish Virus Infection Mimics Natural Infection of Channel Catfish [PDF]
Channel catfish virus (CCV) causes a severe hemorrhagic disease in channel catfish fry and fingerlings. CCV epizootics are associated with elevated water temperatures and high mortality rates. Survivors of acute disease are latently infected with i virus.

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

A Review of the Applications and Challenges of Pulsed Electric Fields in Fish Ecological Protection
ABSTRACT The use of pulsed electric fields (PEF) to regulate fish swimming patterns, especially during migratory channel restoration in dammed rivers, faces significant operational challenges. These challenges can generally be attributed to the multifaceted nature of fish behaviour and limitations in research on physical interception methods.

Techniques of producing monosex or sterile population of fish for aquaculture -- a review of selected literature [PDF]
The need to develop techniques that can make the male grow faster in many species of fish as well as the female in some other species cannot be over-emphasized.
