Reproductive tactics and larval development of bigeye flounder, Hippoglossina macrops, off central Chile

Abstract: Through a series of ichthyoplankton surveys carried out off central Chile, we characterize the offshore spawning and coastal nursery ground of the bigeye flounder Hippoglossina macrops. Eggs were collected in higher abundances over the continental shelf during late winter, over the shelf-break in mid spring, and at the continental slope in late summer, showing a seasonal depth gradient in spawning. No significant spawning was detected nearshore (less than 8 km offshore). Field data suggest a longitudinal progr… Show more

“…En relación a lo anterior, H. macrops, se caracteriza por disponer los ojos en el lado izquierdo, la abertura urinaria en el lado oculado (izquierdo) y el ano en el lado ciego (derecho). En el caso de caracteres de huevo y de larvas descritas para la familia Paralichthyidae, éstas poseen un huevo con una gota oleosa y la migración del ojo comienza entre los 11 y 16,6 mm; sin embargo, se distinguen de otras especies de la familia porque sus larvas son de mayor tamaño y no presentar radios prolongados en la aleta dorsal anterior (Landaeta et al 2006), aspectos que también fueron reportados para Hippoglossina oblonga e H. stomata (Sumida et al 1979, Fahay 1983.…”

“…They belong to Achiropsettidae and Paralichthyidae (Sielfeld et al 2003). Among these, only the larvae of commercially important species have been described, as is the case of Hippoglossina macrops which can be found from Mexico to Punta Arenas (Landaeta et al 2006), Paralichthys adspersus and P. microps, distributed from Peru to 46° and 50°S in Chile, respectively (Zuñiga & Acuña 1992). As for Achiropsettidae of the region, their early stages have been poorly studied.…”

“…During pre-flexion, T. naresi develops a pigment patch in the dorsal finfold, near the midpoint between the anus and the tail tip, which is absent in larval H. macrops (Landaeta et al 2006). Both species display a pigment patch in the anal finfold.…”
