Also, given the large number of exploited protogynous species among sparids and many other families, and the need to predict the effects of fishing, it is important to determine whether such behavior-related selectivity characterizes most fishes with this mating system or whether it is restricted to certain serranids.
This sparid is one of the most abundant, potentially exploitable reef fishes in the northeastern GOM but is only lightly fished there, entirely by hook-and-line gear.
Late gonochorism, protandry, protogyny, and hermaphroditism are the recognized reproductive styles of sparids (Smale, 1988; Buxton and Garratt, 1990).
Pair-spawning sparids such as Chrysoblephus laticeps have low male GSI ([+ or -] 10% of female) during the spawning season (Buxton, 1990).
Like many other South African sparids, carpenter are summer spawners (Buxton and Clarke, 1986; Buxton and Clarke, 1991; Buxton, 1993).

Abstract--The carpenter seabream (Argyrozona argyrozona) is an endemic South African sparid that comprises an important part of the handline fishery.
The carpenter seabream (Argyrozona argyrozona), known as "carpenter" regionally, is an endemic South African sparid found between St Helena Bay and KwaZulu-Natal (Fig.
The application of yield-per-recruit models to two South African sparid reef species, with special consideration to sex change.
Indeed, there is good evidence that the abundance of this sparid in the Blackwood River Estuary in southwestern Australia declined markedly between the 1970s and 1990s as a result of a combination of commercial and recreational fishing activities (see Valesini et al.
butcheri could be used for aging this sparid when there were six or less opaque zones present (Fig.
As pointed out by Blaber (1974) during his study of another sparid, Rhabdosargus holubi, which likewise ingests a large amount of algal material, the volume of digestible material consumed is small.
