| description | The cichlid Hypsophrys nicaraguensis is a popular fish known as butterfly, and despite its widespread use as pets, little is known about its reproductive biology. In order to contribute to this knowledge, the study describes the relevant larval development characteristics, from adult and larval cultures in captivity. Every 12h, samples of larvae were collected and observed under the microscope for larval stage development, and every 24h morphometric measurements were taken. Observations showed that at 120h, some larvae had swimming activity and the pectoral fins development was visible; at 144h, the dorsal fin appear and all larvae started food intake; at 168h, the formation of anal fins begins, small rudiments of pelvic fins emerge, the separation of caudal fin from anal and dorsal fins starts, and the yolk sac is reabsorbed almost completely; at 288h, the pelvic fins starts to form; at 432h, the rays and spines of dorsal and anal fins can be distinguished, both the anal and the dorsal fins have the same number of spines and rays as in adults. After 480h larvae have the first scales, ending the larval stages and starting the transformation to fingerlings. Larvae were successfully fed with commercial diet. Rev. Biol. Trop. 59 (4): 1679-1684. Epub 2011 December 01.<br>Hypsophrys nicaraguensis (Agassiz 1859) se conoce comúnmente como "moga amarilla" o "butterfly", se distingue por su gran mancha negra en medio costado, atravesado o no por una estría lateral, su cola recortada y el perfil de la cabeza curvo con la boca en posición inferior. Con el propósito de contribuir al conocimiento de la biología reproductiva de Hypsophrys nicaraguensis, se describen las características más relevantes del desarrollo larval. Cada 12h se tomaron muestras de larvas cultivadas en cautiverio para observar la evolución del desarrollo larval y cada 24h se realizó el registro de las medidas morfométricas. Entonces se observó que a las 120h algunas larvas pueden nadar y se comienzan a formar las aletas pectorales; a las 144h inicia la formación de la aleta dorsal y todas las larvas empiezan a comer; a las 168h se da la formación de la aleta anal, los rudimentos de las pélvicas se van formando, las aletas anal y dorsal se separan poco a poco de la aleta caudal y el saco vitelino es reabsorbido casi completamente; a las 288h se observa el inicio de la formación de las aletas pélvicas; a las 432h se distinguen radios de espinas en las aletas impares y las aletas anal y dorsal alcanzan el mismo número de radios y espinas que un adulto; después de las 480h se forman las primeras escamas y concluye el desarrollo larval y da el inicio de la etapa de alevín. |
