“…El peso de las hembras, los diámetros ovocitarios y el porcentaje medio de núcleos migrando antes de la primera inyección hormonal fueron similares para todos los grupos experimentados, ello hace muy confiables los resultados obtenidos en particular en cuanto a los aumentos de los diámetros ovocitarios durante los procesos inductores, condición varias veces requerida para el análisis de este evaluador (22,23).…”

Objetivo. Comparar la respuesta a la maduración final de las ova y la tasa de ovulación usando dos tratamientos hormonales en hembras de Pimelodus pictus. Materiales y métodos. Hembras maduras recién capturadas fueron superestimuladas con Extracto de Hipófisis de Carpa (EHC) y mezcla del análogo de la hormona liberadora de la gonadotropina de salmón más domperidona, Ovaprim®. Se utilizaron dosis totales de 5.5 y 7.7 mg/kg, y 0.5 y 1 ml/kg respectivamente, dividida en dos dosis, e inyectadas con un intervalo de 12 h (10% de la dosis total en la primera inyección y 90% en la segunda). Resultados. Con tiempo de latencia de 6 h 30±20 min a 27.4±0.2°C. Las hembras en todos los tratamientos respondieron por sobre el 50%, siendo mayor la respuesta en ambos protocolos para EHC (p

“…Hormonal treatments allow the conclusion of the process through ovulation and spawning (Cárdenas, 2011;2012;Papadakis et al 2013). In the Sciaenidae family, Tucker (1998) reported 12 species induced with treatments such as Human Chorionic Gonadotropin (hCG), Suspension of Pituitary (SP), and Gonadotropin-Re-Spontaneous spawning in captivity of the first generation hatchery-produced weakfish, Cynoscion squamipinnis Koumoundouros et al 2005), Argyrosomus japonicus with LHRHa (Jiménez et al 2005;Musson & Kaiser, 2014), and Micropogonias furnieri with hCG (García-Alonso & Vizziano, 2004). In Costa Rica, the spotted rose snapper, Lutjanus guttatus, was induced to spawning using carp pituitary extract and hCG in different doses (Valverde & Boza, 1999;Boza-Abarca et al 2008;; however, after induction, which produced only one spawning, fish maintained in captivity produced serial spawns for three months (Boza-Abarca et al 2008).…”

“…This species has been successfully induced with GnRHa implants (Duncan et al 2012;Mylonas et al 2013b), using Luteinizing HormoneReleasing Hormone Analog (LHRHa) injections (Gamzis & Neke, 2008;Ballagh et al 2011;Cárdenas, 2012;Duncan et al 2012;Mylonas et al 2013a), hCG injections (García-Alonso & Vizziano, 2004), or GnRHa or GnRH injections and implants (Jiménez et al 2005;Duncan et al 2007a;Cárdenas et al 2008;Cárdenas, 2011;2012;Duncan et al 2012). Other Sciaenidae species have been induced to spawning; for instance, Umbrina cirrosa has been induced with GnRHa (Jiménez…”

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.
