Commercial Fishing and
Aquaculture
• Shrimp Industry most valuable fishery in
U.S.
• 230,000,000 pounds of product
• $379,000,000 ex-vessel value (decreased)
• U.S. consumption – 1.1 billion pounds
• 700,000,000 pounds of imports
• High dollar commodity does not translate
into high margin enterprise for producers
Permitted Offshore Shrimp Vessels
• 2671 in January ’04
• 65-100’ lengths
• Average crew of 3
• Freezer equipped – 90 %
• 30-50 day trips
• Often highly migratory
• Generally less than 50 fathoms
• Some specialty fishing (royal red shrimp)
Inshore Vessels
• Texas + 1000
• Significant numbers throughout Gulf
Shrimp Fishery Applications
• Information to provide efficient running
conditions
• Predictability of Shrimp Concentrations
Currently some seabed features are
consistent with production
Knowledge of past harvests not always
helpful
• Sophistication/Understanding of Potential
Shrimp Fishery Applications
• Advancement of Biological Understanding
Larval Transport
Migrations of Sub-adults and Adults
Impacts of Physical and Chemical Factors
Hypoxic/Anoxic Areas
Noxious Blooms – Red Tide
Shrimp Vessels of Opportunity
• Cooperation exists
• Passive Systems probably necessary
• Florida – Texas Within 50 fathoms
• Some outside of the continental shelf
