“…In a general way, the migration of this species is considered very complex, being observed and described in a general model by Goulding [46], and detailed later on by Ribeiro [47]. This description of the migratory circuit was also confirmed by Vazzoler and Amadio [45] and Vieira et al [48]. The fat-fish migration phase described by Ribeiro [47] is particularly important for the dispersion of the jaraquis to other tributaries of the Solimões-Amazonas system and happens in the middle of the full-flood seasons (from March to June).…”

In search of traditional bio-ecological knowledge useful for fisheries co-management: the case of jaraquis Semaprochilodus spp. (Characiformes, Prochilodontidae) in Central Amazon, Brazil

The jaraquis (Semaprochilodus spp.) are the most abundant group in the fishing landing in Manaus. However, just command and control management strategies have been used by the fishery governmental agency in the region without the power to enforce centralized decisions. The fishermen and their culture represent a source of information on dynamics of the resources and aquatic environments, fundamental in making possible the co-management of the fishing resources. The present study aims to contribute to management through identification of common information available in scientific and traditional knowledge about the jaraquis' bio-ecology. There were 57 semi-structured interviews recorded with fishermen of Manaus and rural areas of Manacapuru in 2002 concerning biological and ecological aspects. Similarity was observed between scientific and traditional knowledge in the following items: size of first sexual maturation, spawning type, parental care, trophic relationships and migratory behavior, as well as in some aspects of the mortality and growth of the species. However, there was less ethnoicthyological information on fecundity and the determination of the age and growth of adult fish. Common information would be used preferably by agencies to start an effective and technical dialogue with commercial and riverine fishermen to design management plans in a decentralized strategy.

“…It has considerable economic importance for commercial fishing and for breeding in captivity (Calcagnotto and Toledo-Filho 2000). It is being caught in increasing numbers, threatening the natural inventory of the species (Isaac and Ruffino 1996;Vieira et al 1999;Garcia et al 2009). …”

Isolation and characterization of tri and tetranucleotide microsatellite markers for the tambaqui (Colossoma macropomum, Serrasalmidae, Characiformes)

We isolated 13 tri and tetranucleotide microsatellite markers for the species Colossoma macropomum that can be used in management programmes for this species of Amazon fish. This panel of microsatellite markers was used in the genotyping of 20 individual specimens collected in the lakes of Ó bidos city, in the Brazilian Amazon. The number of alleles per locus varied from four to ten. The observed heterozygosity varied from 0.31 to 0.95. We observed no significant deviation from the expected Hardy-Weinberg equilibrium assumption. In the sample investigated, it was not possible to identify any significant linkage disequilibrium among the 78 possible loci pairs. In our analysis, we found no indication of genotyping error attributed to stutter bands, large allele dropout or null alleles.

“…The greatest abundance of adult C. macropomum was recorded in the no‐take zone, which may have contributed to the increase in the reproductive potential of the species, as larger C. macropomum individuals are usually more fertile and produce higher‐quality eggs (Vieira et al . ). Lakes without fish exploitation in floodplains could help protect biodiversity, specifically fish stocks that would disperse out of the no‐take zones, providing individuals to surrounding areas used by fishers (Russ et al .…”

Fisheries zoning and the influence of biotic and abiotic factors in the spatial distribution of Colossoma macropomum (Cuvier) in the Piagac ßu-Purus Sustainable Development Reserve, Central Amazon, during 2012-2013 were evaluated. The relative abundance and population parameters of the C. macropomum were compared between conservation (no-take zone) and fishing (open to fishing zone) lakes. The fish were collected by experimental fishing in 2012 and 2013. A total of 296 individuals were captured, most of which were from the conservation lakes (62.8%). Higher proportions of larger adults and individuals were found in the conservation lakes, although no significant difference in the average C. macropomum catch-per-unit-effort was found between the lake categories. Abundance was positively influenced by zooplankton density (r 2 = 0.53, P < 0.03). Therefore, it is hypothesised that conservation lakes may serve as refugia for juveniles due to the high availability of planktonic food available during the dry season. Although there were environmental differences between the two lake types, the relative success of management models that use no-take zones in freshwater habitats was highlighted. Finally, the importance of zooplankton as a factor in the distribution of C. macropomum among floodplain lakes was emphasised.
