22 June 2010 Fig. 4. Spotted Rose Snapper juveniles production. spotted snapper is possible and can provide a sustainable alternative to other species from the tropical American Pacific countries for increased marine production. In the future, the focus of spotted rose snapper culture will be to increase links with the private sector and international agencies, to increase production at the laboratory level, growth at the farm level and spread low cost biotechnology from Mexico to Ecuador.

The PMP claimed three aquaculture areas. After day 45 post hatch, juveniles were moved to the co-management pilot sea farm. Prepared feed evaluations were conducted by Corporación PIPASA using two cages (6x6x6 m, 108 m3) containing 4,000 juveniles each. Two diets were tested at different times during the culture period (Table 1). The first trials at the pilot farm produced mixed results. During the first 18 months, 12,057 spotted rose snapper (4,320 Kg) were sold from five partial harvests. Fish were sold to local markets at an average weight was 0.36 Kg for US$3.71/Kg for a total of US$4,771 in sales (Table 2). Conclusions Using a participatory process and management strategy, Parque Marino del Pacífico and the Universidad Nacional created a pilot laboratory juvenile production program. Lack of expertise and finance were avoided by joining efforts with other public agencies. Cooperation from ICDF helped support the critical phases, including the creation of a marine pilot farm that allowed larger production. Culture of rose
