Genetic Variation of the Endangered Neotropical Catfish Steindachneridion scriptum (Siluriformes: Pimelodidae) [PDF]

Frontiers in Genetics, 2018
Steindachneridion scriptum is an important species as a resource for fisheries and aquaculture; it is currently threatened and has a reduced occurrence in South America. The damming of rivers, overfishing, and contamination of freshwater environments are the main impacts on the maintenance of this species.

Photoperiod influence on the cultivation of Steindachneridion scriptum (Pisces, Pimelodidae) juvenile [PDF]

Brazilian Archives of Biology and Technology, 2008
This study aimed to evaluate the influence of photoperiod on juvenile suruvi (Steindachneridion scriptum) in six photoperiods: 24L-0D (L= Light; D= Dark), 18L-6D, 14L-10D, 10L-14D, 6L-18D and 0L-24D. Juveniles measuring 176.8 ± 13.2mm and weighing 60.2 ± 16.0g were distributed in eighteen 150-L aquariums, stocked with 8 juveniles per aquarium.

Environmental DNA and Conventional Sampling Capture Complementary Patterns of Ichthyofaunal Diversity in the Selangor River Estuary, Malaysia

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Mangrove estuaries are a key ecosystem for coastal fishery resources, especially in developing nations such as Malaysia. Using identical sampling points and duration for both eDNA metabarcoding and conventional sampling, fish community analyses highlight shared and unique taxa, variable taxonomic resolution, and the complementarity of eDNA ...

Fossil freshwater fishes from the Pliocene of northern Colombia and the palaeogeography of northern South America

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Freshwater fishes from the northwestern Colombian Andes are reported from the Pliocene Sincelejo and Ware formations. A total of 10 taxa have been identified, involving two orders, five families and nine genera. Characters from dental morphology, fin spines and cranial bones are provided as taxonomic tools for the study of fossil fishes.
