Although groupers present desirable traits as an aquaculture species, the high cost of feed for the carnivorous fish limits expansion of grouper culture. The author performed two trials to evaluate the performance of tiger grouper juveniles fed soybean meal-based feeds. 

A collaboration among the Center for Aquaculture Research in Colombia, Center for Research, Education and Recreation, and University of Miami is working to adapt the latest aquaculture technology available worldwide to local conditions and create opportunities for farming new commercial species in Colombia. 

Fishmeal sparing in aquafeed is often limited by the presence of anti-nutritional factors found in plant-derived feedstuffs. Fermentation may be a cost-effective means of addressing such factors and improving utilization of plant ingredients in feed. 

A new venture under development in the Bahamas will capitalize on Tropic Seafood’s established logistics and infrastructure to diversify its operations from processing and selling wild fisheries products to include the culture of grouper and other marine fish. 

The government of Ecuador has set the legal framework for leasing mariculture sites and the conditions under which to apply for a lease. This commitment to marine fish farming was also shown by the extension of credit lines. 

In its efforts to advance sustainable aquaculture practices and the use of soy-based feeds in Southeast Asia, the American Soybean Association International Marketing Program (USAIM) has identified several challenges. 

Taurine may not only improve growth and performance, but also is required to reduce nutritional diseases such as green liver disease and low hematocrit levels in some fish. 

Most marine fish have pelagic eggs with large pools of free amino acids of fairly constant proportion regardless of species. The amino acids provide energy for metabolism and are an important nutritional asset for growing embryos. 

Marine fish farming in Brazil appears promising. A new cobia research network will support industry growth through standardization, development of technology and training. 

Research has been directed toward developing compound microdiets to ameliorate variability and poor nutritional quality of live food. 

In the ongoing challenge of developing larval feeds for aquaculture, thraustochytrids – nonphotosynthetic, heterotrophic marine organisms – have potential as a source of fatty acids. 

Harbor Branch Oceanographic Institution researchers have developed marine fish culture methods on an experimental to pilot scale. 

A combined effort led to major breakthroughs in marine fish aquaculture in the southeastern United States and Caribbean in 2002.
