Summary
The commercial lisa fish group comprises several genera and perhaps 10 species. They are rarely separated in fishery statistics, although regionally one species is usually more important than others. The most heavily exploited species are Schizodon fasciatus, Schizodon vittatus, Leporinus fasciatus, Leporinus friderici, Leporinus trifasciatus, Rhytiodus microlepis and Rhytiodus argenteofuscus. These lisa species are predominantly herbivorous and consume fruits, seeds and herbaceous plant material. Many species also feed partly on arthropods and small fishes. Most commercial lisa species are migratory and are caught during their two annual migrations. They are also caught in flooded-soil waters with the aid of nets.
Taxonomy
- Kingdom: Animalia
- Phylum: Chordata
- Class: Teleostei
- Order: Characiformes
- Family: Anostomidae
- Taxon category: Family
Distribution
Wide distribution in the Amazon basin. Catches are concentrated mainly in the Central Amazon, Amazon Estuary, Tocantins, Lower Amazon and Peruvian Amazon.
Threat status
(Insufficient data)
Reproduction
Spawning at the beginning of the rising-water season. Commercial species undertake seasonal reproductive migrations.
Feeding
These lisa species are predominantly herbivorous and consume fruits, seeds and herbaceous plant material. Many species also feed partly on arthropods and small fishes. Most commercial lisa species are migratory and are caught during their two annual migrations. They are also caught in flooded-soil waters with the aid of nets.
Habitat
Amazonian rivers and floodplains. Many species use flooded forests and associated environments during part of their life cycle.
Uses, management and conservation
Species grouped within Anostomidae constitute a fishery resource of regional importance in the Amazon basin. Potential production is estimated at nearly 4,000 tonnes and marketing is oriented mainly toward regional markets. Within Amazonian fisheries they are considered third-category commercial species and are used for local consumption in various countries of the basin.
