Isolation, culture and evaluation of Chaetoceros muelleri from the Caribbean as food for the native scallops, Argopecten nucleus and Nodipecten nodosus

The potential of the Caribbean strain Chaetoceros muelleri (CHA-C-04) to be produced and used as diet of two commercially important native scallops (Argopecten nucleus and Nodipecten nodosus) was assessed, using the non-indigenous Chaetoceros calcitrans strain, as a control. Growth and biomass of bo...
