Determinação de idade e crescimento do mapará (Hypophthalmus marginatus) na Amazônia Central

Abstract: RESUMOO presente trabalho visa contribuir para a conservação e manejo do mapará (Hypophthalmus marginatus), um importante recurso pesqueiro de exportação do Amazonas para o qual é necessário conhecer informações essenciais de sua dinâmica de populações. Para contribuir à esta finalidade, o presente trabalho estabeleceu como objetivo identificar o par de otólito mais adequado para leitura de anéis etários, determinar os parâmetros de crescimento do mapará (H. marginatus), Amazônia Central, Amazonas -Brasil.

“…Estimation of the fish length at each age using rings reading in calcified structures such otoliths (e.g., backcalculation methods) requires to assess the length as function of the structure rings radius (Cutrim, Batista, 2005). For M. furnieri stocks in Southeast Brazil the average lengths back-calculated did not show a clear pattern, resulting in weak adjust considering the high individual variability in otolith size, i.e, fishes of a given size have a wide variability in otoliths size.…”

“…The use of otoliths in studies of age and growth is a scientific breakthrough of great importance to fisheries science and has been successfully employed, as the case of important fishery resources widely distributed, such as the Brazilian codling Urophycis brasiliensis (Andrade et al, 2004), mapará Hypophthalmus marginatus (Cutrim, Batista, 2005), white mullet Mugil curema (Santana et al, 2009), snowy grouper Epinephelus niveatus (Costa et al, 2011), lebranche mullet Mugil liza (Garbin et al, 2014), among others. The high reliability of these calcified structures is attributed to its protection within the auditory capsules, not suffering degeneration as the scales, being also more stable structure and composition over time (Panfili et al, 2002), thus providing more accurate information on age and growth studies.…”

“…They are rheophilic fish and depend on the natural river flow to perform their reproductive functions (CARVALHO, 1980). They differ from other members of the Pimelodidae in their feeding habits and their location in the water column: whereas most species in this family have demersal carnivorous habits, maparás have pelagic planctophagous habits (CUTRIM & BATISTA, 2005). Because of the great acceptance of the species H. marginatus in consumer markets, studies are being conducted to demonstrate the potential of this species for aquaculture (COSTA et al, 2010).…”

“…Na Amazônia Central estudos sobre dinâmica abordando o crescimento foram realizados determinando a idade dos peixes por meio de leitura de estruturas calcificadas em matrinxã, Brycon amazonicus (Spix & Agassiz, 1829) (Werder 1983), aracu, Schizodon fasciatus Spix & Agassiz, 1829 (Fabré & Saint-Paul 1998), tambaqui, Colossoma macropomum (Cuvier, 1816) (Penna et al 2005), mapará, Hypophthalmus marginatus Valenciennes, 1840 (Cutrim & Batista 2005) e piracatinga, Calophysus macropterus (Lichtenstein, 1819) (Perez & Fabré 2009), a maioria de estoques pesqueiros de importância comercial. E, por causa da dificuldade de se trabalhar com estas estruturas, desde a década de 80, métodos indiretos baseados na frequência de comprimento vêm sendo utilizados para a obtenção de informações da dinâmica de estoques pesqueiros.…”
