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).

Red sea bream (Pagrus major) (Table 1) eggs can easily be distinguished from those of other sparids
also found in Japan, such as Acanthopagrus latus, by differences in egg size and spawning seasons, and from those of Evynnis japonica by differences in spawning seasons (Ikeda and Mito, 1988; Kinoshita, 1988; Hayashi, 2000).
Some commercially important fish species were also found in the stomachs of tope shark; sparids
As with other sparids, a narrow opaque zone is laid down in the otoliths of A.
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.
