“…Winter flounder (Stoner et al, 1999), greenback flounder (Pankhurst & Fitzgibbon, 2006) and common sole (Baynes et al, 1994) spawned during the night. Kobe flounder (Moyer et al, 1985) spawned during the day in association with the high tide. Common sole (through video recordings; Baynes et al, 1994) and Senegalese sole (through egg collection; Oliveira et al, 2009) were observed to spawn in the first part of the night, which was actually at a similar time (19:00- Figure 4.…”

“…This "following" behaviour was associated with spawning and was uncommon outside of the spawning period. An important aspect of the courtship in the four Bothidea species (Moyer et al, 1985;Konstatinou & Shen, 1995;Manabe et al, 2000;Carvalho et al, 2003) and the bastard halibut (Manabe & Shinomiya, 2001) was that the males defended a territory that included a harem of females or females visited the defend territory for courtship and spawning. These five species were studied in the natural environment.…”

“…Wild stocks held in captivity spawn eggs of sufficient quantity and quality to form the basis of commercial production (Anguis & Cañavate, 2005;Martin et al, 2014). However, wild Senegalese sole breeders appear to exhibit dominance in the spawning tanks as microsatellite analysis of paternity has demonstrated that 8.7% to 51.7% of breeders actually participated in spawning Flatfish spawning behaviour has been described to varying degrees for nine species, from four families, which are four Bothidea species: kobe flounder (Crossorhombus kobensis) (Moyer et al, 1985), eyed flounder (Bothus ocellatus) (Konstatinou & Shen, 1995), large scale flounder (Engyprosopon grandisquama) (Manabe et al, 2000) and wide-eyed flounder (Bothus podas) (Carvalho et al, 2003); three Pleuronectidae species: winter flounder (Pseudopleuronectes americanus) (Breder, 1922;Stoner et al, 1999), European plaice (Pleuronectes platessa) (Forster, 1953), greenback flounder (Rhombosolea tapirina) (Pankhurst & Fitzgibbon, 2006); one Soleidae, common sole (Solea solea) (Baynes et al, 1994) and one Paralichthyidae species, bastard halibut (Tarphops oligolepis) (Manabe & Shinomiya, 2001). The act of gamete release described for eight of these species was strictly paired spawning when a single male released gametes with a single female.…”

“…The males were more active than females (Baynes et al, 1994;Stoner et al, 1999) and played a more active role in the courtship by displaying to the largely stationary female (Moyer et al, 1985;Manabe et al, 2000;Manabe & Shinomiya, 2001;Carvalho et al, 2003;Pankhurst & Fitzgibbon, 2006). The behaviours of the male display included raising the head, arching the body, waving the pectoral fin, short upward swims, and touching or resting on the female (Moyer et al, 1985;Manabe et al, 2000;Manabe & Shinomiya, 2001;Carvalho et al, 2003;Pankhurst & Fitzgibbon, 2006).

cies and also within some species. Mate selection and gamete release is a key factor that determines which genes or phenotypes are either passed to the next generation or lost (Berglund, 1997;Edward, 2015). Therefore, the description and understanding of a species spawning behaviour has implications for evolution and practical applications for aquaculture and conservation biology to maintain genetic pools and improve stocks. RESEARCH ARTICLE OPEN ACCESS AbstractSenegalese sole (Solea senegalensis) have a high potential for aquaculture that is hampered by reproductive behavioural problems. These problems result in limited breeder participation in spawning. The present study provided an ethogram and described mate selection and spawning of captive wild Senegalese sole. Two tanks of breeders were studied that had 29 and 25 breeders (mean weight = 1.6 ± 0.1 kg). The behaviour was studied during 20 periods of 24 hours: 10 periods where spawning events were recorded and 10 control periods without spawning events. Periods where spawning occurred had three times more locomotor activity than periods without spawning. Two distinct behaviours, termed the "following" behaviour and the "coupled swim", were only observed during periods with spawning. The courtship sequence (n=12) began with males predominantly involved in "following" behaviours, whilst females remained mainly stationary on the bottom of the tank. Males rested on the females and encouraged the females to begin swimming. When the female began to swim the male swam under the female and the pair made a "coupled swim" to the surface to release gametes. Gamete release was strictly in pairs of one male with one female. Failed "coupled swims" without gamete release were 5.6 times more frequent than successful "coupled swims". Mate selection was evident as the sole engaged in: paired spawning, males displayed to females, males encouraged females to spawn and females accepted or rejected the male's advances. The mate selection process provided the opportunity for fish to dominate the spawning and also demonstrated how fish were excluded from spawning.
