“…In the present study oocyte diameter was measured at the start of the experiment when the females were selected and the actual oocyte size before hormone application was not known. Duncan et al (2012) and Mylonas et al (2013a) measured oocyte diameter immediately before hormone application. Stress is accepted as one of the principal factors that cause reproductive dysfunctions and that affect a GnRHa spawning protocol (Ibarra & Duncan, 2007;Mañanos et al, 2008;Mylonas et al, 2010).…”

“…Wild meagre have been spawned using GnRHa administered as a single injection of 20 µg kg -1 and in ethylene vinyl acetate (EVAc) implants of 50 µg kg -1 (Duncan et al, , 2012. Meagre reared in captivity were also spawned using GnRHa administered in EVAc implants of 46-92 µg kg -1 (Mylonas et al, 2011(Mylonas et al, , 2013a). In the wild meagre, the single injection gave lower hatching rates and egg size than the implant (Duncan et al, 2012) and it was suggested that the single injection protocol could be improved.…”

“…In the wild meagre, the single injection gave lower hatching rates and egg size than the implant (Duncan et al, 2012) and it was suggested that the single injection protocol could be improved. The spawning patterns between GnRHa treatments were also different, the implants gave more spawns (Duncan et al, 2012;Mylonas et al, 2011Mylonas et al, , 2013a, but after initial large spawns, smaller spawns were obtained that counted for approximately 25-30% of all the eggs spawned (Mylonas et al, 2011(Mylonas et al, , 2013a. A single GnRHa injection gave a few large spawns and no smaller spawns and Duncan et al (2012) suggested that the differences in spawning pattern between injection and implant were related to the type of ovarian development and spawning strategy.…”

The aim of this study was to evaluate the spontaneous spawning of the first generation of weakfish (Cynoscion squamipinnis) reared in captivity in order to conduct restocking programs and mariculture projects. Juveniles obtained from spontaneous spawning of wild fish caught in the Gulf of Nicoya were reared at the Laboratory of Marine Fish Reproduction and Culture in the Juan Bertoglia Richards Marine Biology Station, Universidad Nacional, Puntarenas, Costa Rica. Fish were kept in 18 t tanks, with constant water exchange (100% per day), at a temperature of 26.73 ± 1.15°C, 32.60 ± 2.69 PSU salinity, and 6.20 ± 0.61 mg/L dissolved oxygen. Every two months croakers were anesthetized and examined for sexual maturity. In January 2011, maturity of one female was confirmed by ovarian biopsies, and oocytes of 0.4-0.6 mm diameter were observed; also fluid semen was obtained from males through abdominal massage. In March 2011, a period of spontaneous spawning began, without any environmental or hormonal stimulation. In total 34 spawns were recorded from March to October 2011, for an average of 85,996 eggs, with a maximum production of 461,000 eggs and a minimum of 4,500 eggs. Fertilization percentage was 10-80%, with an average of 53.09 ± 26.97%. No significant correlations were found between spawns and environmental variables such as temperature, salinity, dissolved oxygen, tides, moon phases and precipitation.

“…En estudios recientes, se ha determinado que las corvinas alcanzan el desarrollo gonadal en cautiverio, sin embargo, necesitan la inducción al desove mediante tratamientos hormonales (Cárdenas, 2012;Duncan et al, 2012;Mylonas, Mitrizakis, Papadaki, & Sidelaki, 2013a;Mylonas et al, 2013b), como inyecciones de hCG (García-Alonso & Vizziano, 2004), o inyecciones e implantes de GnRH (Cárdenas, 2011;Duncan et al, 2012). Según Jimé-nez et al (2005) y Cárdenas (2011), la única especie con desoves espontáneos en cautiverio es el corvinón ocelado (Sciaenops ocellatus).…”

Spontaneous spawning, ontogeny and growth in captivity of Cynoscion squamipinnis (Perciformes: Sciaenidae). The croakers or drums are commercial species, which have been overfished in the Nicoya Gulf, Costa Rica. This study aimed to describe, for the first time, the reproduction and the ontogeny of weakfish, Cynoscion squamipinnis in captivity, in order to perform restocking and mariculture projects. Wild fish (n= 6, 1-2 Kg) were captured and maintained in the Estación de Biología Marina Juan Bertoglia Richards (Puntarenas, Costa Rica) for a two years period (October 2006-December 2008. During this period, maturation stage was monitored periodically by cannula samples in the females (n= 3) and gentle massage in males (n= 3). All fish were stocked in an 18 t tank, with aeration, 33-35 ups of salinity, and a constant temperature (29 ± 1 °C). The spawning period occurred from January to March 2009, producing 162 000 eggs in three spontaneous spawns. The fertilization percentage was 50-60%, and survival after hatching was 60-85%. The egg diameter was 0.852 mm (Standard deviation (SD)= 0.039), and oil drop of 0.269 mm (SD= 0.016). In the embryonary development, the first mitotic division (MD) was observed one hour after spawning (has), the second MD was 1:30 has, the third MD was 2:00 has, the fourth MD was 2:30 has, and fifth MD at 3:00 has. Morule was observed 3:30 has, the blastule 4:30 has, the gastrule 8:30 has, C shape at 10:00 has, and C shape at 12:00 has. After 19 has hatching larvae occurred. The total length (TL) of the larvae was 2.234 mm (SD= 0.122), and the nothochordial length (NL) was 2.179 mm (SD= 0.119). Preflexion stage was observed 49 has, flexion stage was 11 days after spawn (das) (3.767 mm LT (SD= 0.209)), and postflexion stage was 14 das (4.015 mm LT (SD= 0.302)). After 45 das, the juvenile weights 3.68 g (SD= 1.09). Hatch time of the weakfish larvae was minor than of others croaker species. The stages times of embrionary development were a little different from others croaker species, and probably respond to genetic characteristics of each species and the eggs incubation temperature. The spontaneously spawning without broodstock hormonal applications, and the juveniles production in captivity showed that weakfish is a potential species for restocking programs and mariculture projects.
