Line 10:
The origins of industrial shrimp farming can be traced back to the 1930s, when [[Kuruma shrimp]] (''Penaeus japonicus'') was spawned and cultivated for the first time in [[Japan]]. By the 1960s, a small shrimp farming industry had appeared in Japan.{{mn|ros1|Ros04a}} Commercial shrimp farming began in the late [[1960s]] and early 1970s. Technological advances led to ever more intensive forms of shrimp farming, and the growing market demand led to a proliferation of shrimp farms throughout the world, concentrated in tropical and sub-tropical regions. The growing consumer demand coincided in the early 1980s with faltering wild shrimp catches, creating a veritable boom in shrimp aquaculture. [[Taiwan]] was amongst the early adopters and a major producer in the [[1980s]]; its production collapsed beginning in 1988 due to poor management practices and disease.{{mn|isa|ISA00}} In Thailand, large-scale intensive shrimp farming expanded rapidly from 1985.{{mn|abandon|HL01}} In [[South America]], shrimp farming was pioneered by [[Ecuador]], where it expanded dramatically from 1978.{{mn|clennan|McC04}} Brazil had been active in shrimp farming since 1974, but the trade really boomed there only in the 1990s, making the country a major producer within a few years.{{mn|brazil|Nov03}} Today, there are marine shrimp farms in over fifty countries.
