Depth Distributions of Armored Catfish: Predator-Induced Resource Avoidance?

Ecology, 1984
Four species of armored catfish (Loricariidae) have size—specific depth distributions in a Panamanian stream, with larger fish in deeper water. Depth distributions do not change from the dry to the rainy season, despite a two— to three—fold increase in habitat area for larger loricariids. Throughout the year, standing crops of the loricariids' attached

Resource Enhancement by Indirect Effects of Grazers: Armored Catfish, Algae, and Sediment

Ecology, 1990
Armored catfish (Loricariidae) are the major grazers of attached algae in pools of the Rio Frijoles, Panama (9°9' N, 79°44' W). In the dry season, sunny pools were inhabited by °6 individuals loricariids per square metre of grazeable substratum. At these densities, armored catfish depleted algae and cleared sediment from bedrock substrata, leaving ...

Characterization of dermal plates from armored catfish Pterygoplichthys pardalis reveals sandwich-like nanocomposite structure

Journal of the Mechanical Behavior of Biomedical Materials, 2015
Dermal plates from armored catfish are bony structures that cover their body. In this paper we characterized structural, chemical, and nanomechanical properties of the dermal plates from the Amazonian fish Pterygoplichthys pardalis. Analysis of the morphology of the plates using scanning electron microscopy (SEM) revealed that the dermal plates have a ...

A Gap in the Armor: Spearfishing Reduces Biomass of Invasive Suckermouth Armored Catfish

Fisheries, 2020
Abstract Introduced Suckermouth Armored Catfish (SAC; family Loricariidae) have invaded freshwater ecosystems globally. In the San Marcos River, Texas, control of invasive SAC includes spearfishing through public tournaments and contracted spearfishing, yet the effectiveness of these control efforts is unquantified.
