ABSTRACT

Various data were obtained through three years of research on production and marketing of three live bait shrimp:  Litopenaeus setiferus (the Atlantic white shrimp), Farfantepenaeus duorarum (pink shrimp), and F. aztecus (brown shrimp).  Although postlarvae (PL) availability and viral disease outbreaks were major obstacles in most studies, several following conclusions can be made.  A dependable source for native species postlarvae is needed to develop the farm-raised live bait shrimp industry.  Production technologies developed for Litopenaeus vannamei can be used successfully for the culture of live bait white shrimp in race ways and ponds.   Bait-size shrimp can be raised in 64 days from 10-day-old postlarva (PL10).   Live bait white shrimp can be produced in raceways at high density (560PL/m2) with excellent survival (>94%) and yield (3.27kg/m2).  Good growth and survival can be expected when this shrimp was fed a commercially available diet with 45% protein diet (Rangen, Inc., Buhl, ID) or an experimental diet with 20% protein level. Induced maturation, spawning and postlarvae production of pink shrimp are feasible.  More research is needed to evaluate the growth performance of this species under high densities and in outdoor ponds for live bait production.  Wild gravid females of brown shrimp can be used to produce viral pathogen-free postlarvae with good survival.  Further research is needed to determine the feasibility of using this species for the production of live bait under high densities.  Any research with wild shrimp populations will have to ensure that these populations are not infected with virulent viruses.  Supply of wild live bait shrimp in the Gulf Coast States cannot meet demand for great part of the year.  Live bait dealers will be willing to pay higher prices for farm- raised live bait shrimp if quality and supply can be secured.

Induced spawning and postlarvae production technology for pink shrimp was transferred by the P.I. to Personnel of the Crystal River Mariculture Center (CRMC), Crystal River, Florida.  Live bait shrimp production technology was transferred to Harbor Branch Oceanogrphic Institute in Florida and to a private producer in Texas.  Currently the private Texan company is continuing her efforts to develop this new industry with help from the Texas Agricultural Research Station (TAES).  Private producers in Florida, South Carolina and Alabama are considering going into live bait shrimp production.   Revenue generated from live bait sells was use to improve the research capability of the TAES facility in Corpus Christi.  Eight graduate students from Texas A&M University-Corpus Christi, Corpus Christi, Texas, were involved in research associated with the production and marketing of farm-raised live bait shrimp.  Four of these students have submitted their research papers and graduated, with another two expected to graduate within a year.  One paper dealing with the marketing aspect was submitted for publication in a peer-reviewed journal, and results form the three years of studies were presented in 10 national and international professional societies meetings.
