The hermaphroditism in the nature of the fish, result in some species a strategy of reproductive behaviour but in general, its frequency of apparition result a event biological of character rare, for not always such conduct is associated to the same conditions environmental. The objective of the present research was to describe hermaphroditism in Orestias agassi of Titicaca lake in Puno-Peru as a case report. Since 2009, Laboratory Continental of Puno records as activities the monitoring of fishery, where is evaluated inside of its main indicators the total length, standard length, total weight and bowel weight (gonads, stomach and liver). In May of 2014, corresponding to the zone of Villa Santiago-District of Pomata, Province of Chucuito, in laboratory conditions was made a probabilistic random sampling (92 individuals), to which there was an interval rank of 8,6 to 15,2cm of total le...

Este estudio proporciona información sobre reproducción artificial y crecimiento de Orestias luteus en condiciones de laboratorio. La reproducción artificial se realizó en las orillas del Lago Titicaca zona Muelle Barco y las ovas fecundadas se incubaron en el Laboratorio Continental de Puno – IMARPE, en incubadoras tipo Chasse con flujo continuo de agua de 0,5 L/seg a 15 °C de temperatura promedio. Al cabo de 20 días se inició el proceso de eclosión, tuvo duración de tres días, las larvas obtenidas fueron confinadas en acuarios de vidrio de 0,115 m3 . El periodo experimental de crecimiento comprendió 240 días, para ello se utilizó 600 alevinos de carachi amarillo confinados en un acuario de vidrio de 50 x 40 x 40 cm implementado con aireación permanente. Para el mantenimiento del cultivo se proporcionó ad libitum alimento vivo (Chlorella vulgaris, Artemia salina y Daphn...

El manual está fundamentado en la experiencia y resultados obtenidos entre el 2015 y 2018 en el Laboratorio Continental de IMARPE –Puno, Área de Acuicultura. En este manual se detallan los procedimientos para la obtención de alevinos de pejerrey, para lo cual se presentan aspectos como manejo de plantel de reproductores, desove artificial, incubación, obtención de larvas y alevinos y alimentación.

Esta sede del Imarpe viene realizando estudios sobre el cultivo de pejerrey Odontesthes bonariensis en condiciones de laboratorio, hasta la obtención de alevinos. El propósito de la investigación es lograr el desarrollo de nuevos sistemas productivos y metodologías de cultivo que contribuyan a la diversificación de la acuicultura de recursos hidrobiológicos de aguas continentales en la región. Con dicho propósito, se ha elaborado una guía para la obtención de alevinos de pejerrey Odontesthes bonariensis en condiciones de laboratorio, el cual es presentado a continuación y se espera que constituya como una herramienta útil para pescadores artesanales, acuicultores, estudiantes y al público en general que desee desarrollar esta actividad.
