  2. Successful reproduction and rearing of surubim in North America

  3. Embryonic development in Pseudoplatystoma sp. Time after fertilization in hours (h) at 27oC. Black bars = 1 mm. (A) 1 h, 2-cells; (B) 2 h, 4-cells; (C) 4 h, ½ epiboly; (D) 6 h, blastopore closing; (E) 9 h, first somites; (F) 14 h, at hatching.

  4. Surubim catfish (Pseudoplatystoma sp.) February 2007 Columbus, Ohio Yongfang Zhang

  5. Growth of pacu (Piaractus mesopotamicus) in Columbus, Ohio. Environmental conditions control included: temperature, pH, and light regime fluctuations. Arrows indicate duration of water temperature cooling and short day light.

  6. An immature necropsied pacu scanned and assessed via cross sections. An Aloka (Aloka Co., LTD) SSD-500V ultrasound with a Medi-capture USB100 video capture system with an attached camera, and 3.5 MHz convex array probe. AB = Air bladder; Bc = body cavity wall; F = fin; Fo = food; GB = gall bladder; In = intestine; Ki = kidney; Li = liver; M = muscle; R = ribs; St = stomach; VF = visceral fat. Bong-Joo Lee

  7. Work in progress on reproduction of silver arowana (Osteoglossum bicirrhosum) Juveniles 4 weeks after yolk sac absorption, February 24, 2007. Adult, 16 months old, April 2008

  8. Extension workshops on reproduction and rearing of tropical fish in Manaus and Balbina, Brasil, May 2007 Manaus Balbina

  9. Extention workshops on reproduction and rearing of tropical fish in Tingo Maria and Lima, Peru, July 2007 Paiche (Arapaima gigas)
