“…The progressive spread of A. gigas over most of the Amazon Basin has been predicted due to increases in the mean temperature associated with climate change, limited only by altitude and the absence of floodplain environments (Oberdorff et al 2015). However, these predictions did not consider the introduction of A. gigas as nonnative populations in a set of sub-basins upstream of the Madeira River rapids where large floodplains (natural habitats in Madre de Dios and Mamoré rivers) and reservoirs have been established (Doria et al 2018) thereby enhancing its potential for invasion.…”

In the last ten years Araipama gigas, commonly known as pirarucu, expanded its distribution upstream into the Madeira River rapids where it is not a native species. The invasion was favored by escapes from Peruvian fish farms upstream in the Madeira River Basin, where they have been raising pirarucu since the 1970s. Although the Madeira River rapids had formerly represented a geographical barrier to this invasion by limiting floodplain habitats, the construction of the Santo Antônio and Jirau dams in 2011 flooded the two most important falls, replacing the rapids stretch with a lentic or semi-lentic habitat favoring the invasion of A. gigas. Since construction of the dams, fisheries reports have been marked by the decrease of traditional commercial species, coupled with the presence of invasive populations of A. gigas. This example highlights a major emergent threat to artisanal fishing in the Amazonian freshwater system: government policies favoring dam construction and the consequent spread of native fish species used in aquaculture to new regions upstream of waterfalls where they are not native.

“…In 2009, there were 1,200 registered fishermen across this region. The fishing fleet consisted mostly of small wooden fishing vessels (non-motorized and motorized canoes totalled more than 1,000 units) and a few fishing boats (Doria et al, 2018). Non-motorized and motorized wooden vessels (average length 5.8 m) are used for fishing and for transporting fish.…”

“…It is a carnivorous fish and feeds on fish and invertebrates. This species is also important in the Madeira basin, where it represented between 1.0 and 3.6% of total landings before the construction of two hydroelectric dams in the Brazilian portion of the Madeira basin (Doria et al, 2018). Both the aforementioned fish have been identified as sales leaders, besides commanding the highest market prices in the region (Doria et al, 2016).…”

“…Studies of migratory catfish landings are important for the management of their fisheries and help to verify the possible impacts of overfishing and habitat loss resulting from the construction of large hydroelectric plants in the Amazon Basin (Doria et al, 2018). These constructions result in the disruption and modification of the bioecology along large river stretches and making these environments unsuitable for fish species whose migration and reproduction processes rely on the lotic environment and on the presence of rapids (Fearnside, 2013).…”

FISHING PRODUCTION OF <i>Pinirampus pirinampu</i> AND <i>Brachyplatystoma platynemum</i> CATFISH HAS BEEN AFFECTED BY LARGE DAMS OF THE MADEIRA RIVER (BRAZILIAN AMAZON)

The present study analyzed landing events of commercial fishing of two species of large catfish in 11 fish landing sites along the Madeira River, and temporally and spatially characterized the exploitation of these species before and after the closure of the Jirau and Santo Antônio hydroelectric dams. Our results show that the Madeira River dams have negatively affected the fishing production of Pinirampus pirinampu and Brachyplatystoma platynemum catfish, drastically reducing these species' harvest as well as the incomes of regional fishers. If the irreversible loss of these species of Amazonian catfish is to be avoided, public policies and measures for the management and sustainable handling of this fishery resource must be implemented urgently.

“…Declines in the catch of the other large Brachyplatystoma species, however, have contributed to increased catches of B. platynemum in recent years (Petrere, Barthem, Córdoba, & Gomez, : Ochoa et al, ). On the other hand, this species has long been important in the Madeira basin, where it represented between 1.0 and 3.6% of total landings before the construction of two hydroelectric dams in the Brazilian portion of the basin (Doria et al, ).…”

1. In the Amazon, migratory catfishes of the genus Brachyplatystoma are apex predators that are important for fisheries and conservation. The life cycle of Brachyplatystoma platynemum Boulenger, 1898 is poorly known, although it has been hypothesized to be very similar to that of Brachyplatystoma rousseauxii Castelnau, 1855, which uses the entire length of the Amazon basin to complete its life cycle (from the Andes to the estuary). This study provides the first data on the migratory patterns of B. platynemum at the individual level using otolith microchemistry.2. In total, 94 individuals were sampled close to major breeding areas in the Amazon basin (78 fish from the middle and upper Madeira River and 14 fish from the upper Amazon), and their lifetime movements were assessed by measuring variations in 87 Sr/ 86 Sr along transverse sections of their otoliths (ear stones), using laser ablation multi-collector mass spectrometry (LA-MC-ICP-MS).3. The migrations of B. platynemum are not as extensive as those of B. rousseauxii, and do not involve natal homing. Furthermore, the estuary is not a nursery area, at least for fish hatched in the Madeira. Nevertheless, B. platynemum migrates several
