Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

Ecology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

The development of early monitoring tools to detect aquatic invasive species: eDNA assay development and the case of the armored catfish Hypostomus robinii

Environmental DNA, Volume 4, Issue 2, Page 349-362, March 2022., 2022
Hypostomus robinii (2 and 3), a popular freshwater aquarium fish native to tropical and sub‐tropical South America, was introduced in Martinique rivers (4). In this study, we precised the distribution map of this invasive fish species using both eDNA and trapping methods (1).

New method of isotopic analysis: baseline‐standardized isotope vector analysis shows trophic partitioning in loricariids

Ecosphere, Volume 12, Issue 5, May 2021., 2021
Abstract Stable isotope analyses have refined the study of trophic niche diversity within an ecosystem, yet traditional trophic partitioning methods may not be appropriate to identify variation among groups with similar dietary requirements. By building on vector‐based analyses, we introduce a baseline‐standardized isotopic vector analysis (BaSIVA) to ...

Strategies to control invasion of Sailfin Armoured Catfish, Pterygoplichthys spp. in wastewater-fed aquaculture bheries of East Kolkata Wetland, India with suggestion of a modified barrier based on the biological and behavioural characteristics [PDF]

, 2021
Sailfin armoured catfish (Pterygoplichthys spp.), an alien invasive species of family Loricariidae has invaded extensively in wastewater-fed large aquaculture ponds (locally called ‘bheries’) of East Kolkata Wetlands (EKW), West Bengal, India.

Feasibility of using sailfin catfish meal as an alternative to commercial fishmeal in the diets of juvenile guppy (Poecilia reticulata) [PDF]

, 2022
A six weeks feeding trial was conducted to elucidate the effect of fishmeal produced from sailfin catfish (SCM) by replacing imported commercial fishmeal (FM) in the diet of Poecilia reticulata to reduce the cost of feed. Twenty one days old guppy fry (1.

Successful eradication of the non-native loricariid catfish Pterygoplichthys disjunctivus from the Rainbow River, Florida [PDF]

Management of Biological Invasions, 2015
Non-native Pterygoplichthys (Loricariidae) are increasingly introduced and established in tropical and subtropical regions worldwide. Florida (USA) has a long history of introduction of loricariid catfishes. These catfishes are of management concern, particularly when they occupy sensitive habitats such as springs and spring runs. Limiting introduction
