Impacts of Crawfish, Catfish, and Shrimp Imports on U.S. Domestic Prices Young-Jae Lee P. Lynn Kennedy
Common Market Issues Imports increasing (relatively higher marginal cost of production in U.S.) Low domestic prices Decrease in domestic production Domestic consumption increasing (new cuisine, health concerns, etc) Homogeneity (between imported and domestically produced goods)
Crawfish Market Louisiana is the leader in freshwater crawfish production Most crawfish cultured in rice field - rice-crawfish integrated faming system Crawfish are routinely graded into three sizes - large, medium: whole live or whole boiled - small: processed tail meat
Louisiana s crawfish industry was affected negatively by massive imports of crawfish tail meat from China. Imported crawfish tail meat displaced more than 90% of Louisiana s domestic crawfish meat market. Rice-crawfish producers lost markets for small crawfish and were deprived of a significant source of income. Louisiana s crawfish industry lost an estimated 4,000 full-time and part-time jobs
LAES developed management practices to increase production of larger, high-valued crawfish and to reduce production costs to compete with imports. Researchers identified overcrowding, food shortages and overharvesting as the major causes for the harvests of small crawfish. An inter-cropping strategy was developed whereby small crawfish could be relayed into a growing rice crop to increase in size and subsequent market value, while preserving acceptable rice yields. Research continues to develop effective supplemental feeding and forage systems, along with strategies to increase production of large crawfish by preventing overcrowding.
LCES, LDAF, and producer and processor groups worked successfully to have the U.S. Department of Commerce impose an antidumping tariff on the imported Chinese crawfish meat. The Byrd Amendment directs the U.S. Bureau of Customs and Border Protection to distribute monies to companies that petitioned or supported antidumping tariff action

Harvesting farm raised Crawfish under controlled water conditions ensures a quality product Crawfish are washed and inspected prior to boiling. Some are hand selected for live sales
Parboiling is accomplished with specially built equipment operated under careful supervision Crawfish is peeled in a sanitary environment
Packers check the crawfish meat to assure quality The crawfish meat is bagged and iced for fresh shipment, or bagged and quick-frozen
Domestic Crawfish Tail Meat Price: $13.99 Chinese Crawfish Tail Meat Price: $5.99
Catfish Market Mississippi, Arkansas, Alabama, and Louisiana are the leaders in freshwater catfish production - Four states produce 94% of catfish production Three Market Issues for catfish - low prices - increase in imports of catfish from Vietnam - high feed and fuel cost
Since 2000, catfish industry has suffered because of low prices in the market place by the influx of imported catfish Low prices received by producers in 2002 ($0.57/pound) and 2003 ($0.58/pound) have caused economic hardship for Mississippi producers resulting in a decrease of 10,000 acres since 2002. While catfish prices improved in 2004, higher catfish feed prices and increasing fuel prices mostly negated gains.
Imports of Vietnamese catfish have been increasingly displacing U.S. farm-raised catfish in the seafood market at alarming rates, prompting the catfish industry to push for a labeling law as a way to even the playing field. The labeling legislation in both Mississippi and Alabama mandates that only catfish produced by U.S. growers in fresh-water ponds may be labeled as farm-raised catfish.

Shrimp Market Shrimp imports continuously increases From 2000-2003, import volumes of shrimp increased from 466 million lbs to a 795 million lbs. Average unit value of shrimp imported fell $3.48 in 2003 from $5.12 in 2000. However, consumer prices increased from $8.99 to $10.13 during the period, indicating that the middleman makes more money.

Conclusions Domestic price of Crawfish is shown to have a positive relationship with imports of crawfish while domestic prices of Catfish and Shrimp have a negative relationship with imports Imports of Crawfish stimulated by a domestic price increase caused by decreased domestic production
Conclusions (cont.) Crawfish, Catfish and Shrimp were shown to be normal goods Clam and Pork significantly related to domestic crawfish price Trout and Beef significantly related to domestic catfish price Clam, Oyster, Beef, and Pork significantly related to domestic shrimp price.
