“…Environmental and biological seasonality has been considered important in structuring marine communities at all latitudes (Clarke, 1988;Coma et al, 2000;Afeworki et al, 2013;Andrews et al, 2014). The recruitment and abundance of marine invertebrates (including non-native species) through seasons is a result of species-specific interactions with the environment (Tracy and Reyns, 2014).…”

“…The study was conducted on the gently sloping fringing reef of Sheik Said Island (15° 35′ N; 39° 29′ E), Massawa, Eritrea. Despite its inshore location and proximity to the city of Massawa, the reef has high (30–50%) coral cover (Zekeria & Videler, ; Afeworki et al , ) and supports a diverse and abundant grazer community (Afeworki et al , 2013 b ). There is a low‐intensity, canoe‐based fishery around Massawa, but parrotfishes or other reef grazers are not targeted (Tsehaye et al , ).…”

Temporal trends in growth of the rusty parrotfish Scarus ferrugineus were studied on a southern Red Sea fringing reef that experiences seasonal changes in environmental conditions and benthic algal resources. Length increment data from tagging and recapture were compared among periods and sexes and modelled using GROTAG, a von Bertalanffy growth model. The growth pattern of S. ferrugineus was highly seasonal with a maximum occurring between April and June and a minimum between December and March. Body condition followed the seasonal variation in growth, increasing from April to June and decreasing from December to March. The season of maximum growth coincided with high irradiation, temperature increases and peak abundance of the primary food source, the epilithic algal community. There was a decline in growth rate during summer (July to October) associated with a combination of extreme temperatures and lowered food availability. There were strong sexual size dimorphism (SSD) and life-history traits. Terminal-phase (TP) males achieved larger asymptotic lengths than initial-phase individuals (IP) (L(∞) 34·55 v. 25·12 cm) with growth coefficients (K) of 0·26 and 0·38. The TPs were growing four times as fast as IPs of similar size. Three individuals changed from IP to TP while at liberty and grew eight times faster than IPs of similar size, suggesting that sex change in S. ferrugineus is accompanied by a surge in growth rate. The SSD in S. ferrugineus thus coincided with fast growth that started during sex change and continued into the TP. Faster growth during sex change suggests that the cost associated with sex change is limited.

“…). All sexual categories of S. ferrugineus forage in loose groups on the reef crest and parts of the reef flat (Afeworki et al, ). In the deep fore‐reef zone (6–15 m depth), foraging activity was minimal and the abundance of this species was low during non‐spawning periods (Fig.…”

“…In general, the incidence of group‐spawning and streaking tends to be high in larger populations (Warner & Hoffman, ; Kuwamura et al ., ) or in more complex habitats (Robertson & Warner, ; van Rooij et al, ). The high density of the species at the study site (Afeworki et al, ), may explain the observed prevalence of streaking in this population.…”

The present study shows that small non-territorial terminal-phase males of the rusty parrotfish Scarus ferrugineus are reproductively active and are comparable with initial-phase males in behaviour, rates of participation during group-spawning and success in streaking into pair spawning. Large territorial terminal-phase males defend contiguous territories for several hours during the morning where they pair spawn with initial-phase females.
