Arnason, R. The author distinguishes between ocean fish farming and
ocean ranching. The distinguishing characteristic of ocean ranching is
that the released species are unassisted once released into the ocean. Ocean
ranching in turn is classified as pure ocean ranching (animals intended
to be harvested by the entity that released them) and stock enhancement ocean
ranching. The document first relates the experiences in ocean ranching in
Japan, the United States and Iceland up to the mid-1990s. It then describes the
fundamental externality of ocean ranching and finally discusses methodologies
for assessing the costs and benefits of ocean ranching. |
