RESEARCH AND DEVELOPMENT This program is developing new technologies for the production of marine fish. These new technologies will be used to implement a project to achieve sustainable cultures by means of a combination of controlled factors such as breeding, larval rearing and the production and application of live food or inert (microalgae, rotifers, artemia), as well as applying controls and improvements to the nutritional, pathological and genetic aspects.
Staff has been trained in Centro de Investigaciones del Noroeste (CIBNOR) Mexico, in Taiwan supported by International Cooperation and Development Fund (ICDF), in the University of Miami and recently with the Universidad Católica del Norte in Chile.
Research areas are:
C) Genetics: Evaluation of the main genetic characteristics that allow for a selection of previous generations with better reproductive conditions.
Research on the digestive physiology of the Spotted Rose Snapper as well as the biometrics of growth was done with department of Biological Sciences of the National University. They have also done studies on the feasibility, economic profitability and integrate management of cultivation for the Spotted Rose Snapper.

The Parque Marino fundamentally considers the improvement of the quality of life of the costal settlers and to encourage the creation of alternatives methods of research, development and innovation in marine production. The park also encourages the expansion of technology with private companies, those of which allow permit a greater acceleration of marine fish-farming in the country, due to the financial contributions, the exchange of knowledge and contribution of local workers.
The ¨Marine Production Laboratory¨ has managed to develop the technology to produce the seed of he Spotted Rose Snapper (Lutjanus guttatus), maintaining since 2005 the constant production of young fish.
As of 2006, with the technical and financial collaboration of the International and Cooperation and Development Fund from Taiwan, the Instituto Mixto de Ayuda Social and INCOPESCA, floating cages were built for the growth of the Spotted Rose Snapper, located in the Bay of San Lucas Island and managed by the Asociación de Pesca y Cultivo de Isla Venado. This is a pilot project which has demonstrated the technical and financial feasibility to implement marine fish-farming in Costa Rica.
Furthermore, in 2007 our production laboratory in cooperation with INCOPESCA released 60,000 young Spotted Rose Snappers in the Refugio de Vida Silvestre Isla San Lucas, as a part of an objective to repopulate and help maintain the natural population of marine fish in the Nicoya Gulf. 
From the beginning the Parque Marino joined effort with research done in the Marine Biology Department at the Universidad Nacional, focused on Spotted Rose Snapper and production of live food. In spite of not having obtained the development of technology needed, they had to explain many other unknowns that were not researched. 
A) Nutrition: Evaluating different diets to determine best results for growth, pigmentation and survival of the Spotted Rose Snapper in laboratories as well as the floating cages. 
B) Pathology: seasonal presences of pathological agent´s are determined. Also, the protocols, preventative programs and cures are determined for the reproducers of larval culture and fingerlings.
The park collaborated with the Electron Microscopy Laboratory from Universidad de Costa Rica on research of harmful algal blooms (red algae) in the Pacific Coast of Costa Rica.
