Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.

The simple morphology of the sunfish heart

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 1034-1041, June 2025.
Jensen and Lauridsen describe the least curved vertebrate heart to date in seven specimens of Ocean sunfish. By comparison to multiple vertebrates, it is concluded that the highly unusual heart is a recent evolution that relates in part to the extraordinary shape of the body.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Cephalic Musculature of the Pacman Catfish Lophiosilurus alexandri Steindachner, 1876 (Siluriformes, Pseudopimelodidae)

open access: yesJournal of Morphology, Volume 286, Issue 5, May 2025.
The head of the Pacman catfish (Lophiosilurus alexandri [L. alexandri]) is strongly depressed, broad, and with a large mouth, roughly resembling those of Lophius piscatorius and Chaca bankanensis. Also, they are bottom dwellers and have ambush behavior for fish predation.

Restoring mangrove biodiversity: can restored mangroves support fish assemblages comparable to natural mangroves over time?

open access: yesRestoration Ecology, Volume 33, Issue 4, May 2025.
Despite the recent global increase in mangrove restoration efforts, our understanding of the outcomes and recovery of biodiversity and re‐establishing functionality, such as productive fish habitat, is limited due to the lack of long‐term monitoring. Here, we used a space‐for‐time approach to investigate whether restored mangroves attain similar fish ...

Influence of Photoperiod on Productive Gains and Immune Resistance During the Larval Stage of the Neotropical Fish Trachelyopterus galeatus (Linnaeus, 1766)

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
This study evaluated the effect of photoperiod as a productive strategy during the larviculture of the neotropical species Trachelyopterus galeatus. A total of 560 postlarvae, with an average total length and weight of 6.61 ± 0.33 mm and 2.36 ± 0.10 mg, respectively, were randomly assigned to seven photoperiod treatments, each four replicates: (0L:24D)

A new species of spiny driftwood catfish Spinipterus (Siluriformes: Auchenipteridae) from the Amazon basin [PDF]

open access: yesJournal of Fish Biology, 2019
AbstractAn expedition to the middle Rio Purus basin uncovered a remarkable new species of the genus Spinipterus. The new species has a very distinct and conspicuous colour pattern resembling a jaguar and it is almost four times larger than Spinipterus acsi, a small specimen (32 mm LS) from Caño Santa Rita, a right bank tributary of Río Nanay in Peru ...
