Inland Shrimp Farming

Crab Farming



This five-minute video begins with the two panels you see below and the voice of an unnamed narrator saying: “Though the shrimp waters are reported to be reopened...it’s not clear if people will want to eat shrimp that are harvested from the Gulf of Mexico.  ...Can the saltwater shrimp be farm raised?  ...If so, our proposal would be for BP to fund a program that would allow shrimpers to convert to shrimp farmers, and this TV report from NBC 13...tends to support that thesis.”


Here the video shifts to a clip from a TV newscast [Editor: there was no date on the newscast, and I could not confirm the name of the reporter or anything else about the clip when I called the TV station.].


Reporter: “In Greene County among lush green ponds, for twenty-two years Dickie Odom has fed and raised catfish....” [Unless you want to listen to a couple of minutes of information about Odom’s catfish operation, I recommend that you skip ahead to minute 3:00, where he and the reporter begin talking about shrimp farming].


Reporter: “This area has natural inland saltwater.”


Dickie Odom: “This saltwater is not everywhere in Alabama.”


Reporter: “But it’s on Dickie Odom’s farm, where he is now growing more than just catfish.  With no boats, no trawlers, just a casting net, he’s also pulling in Pacific white shrimp.  Farm-raised shrimp processed, packed and even stored far from the coast.  Dickie Odom is one of just a few catfish farmers in the state that are growing shrimp.”


Odom admits that inland shrimping is not a big money maker just yet.  Most of his customers buy straight from the farm or at the Alabama Farmers Market.


Odom is now checking to see if he can grow blue crabs in his saltwater ponds!

Country Reports


Sand Filters and Marine Worms


From Abstract: This study investigated the use of marine worms (Perinereis nuntia and P. helleri, nereidid polychaetes from Moreton Bay in southeast Queensland) in sand filters.  The burrowing of the worms helps prevent the filters from getting clogged, and the worms can be harvested as an exceptionally nutritious feed for shrimp broodstock.  In this study phytoplankton-rich pond waters percolating through sand-worm beds consistently reduced suspended solids and chlorophyll a levels by greater than 50%.  The process also significantly lowered dissolved oxygen, redox and pH levels.


P. nuntia appeared more suitable than P. helleri for stocking sand filters, but it generally exhibited slower growth.  Stocking density influenced growth and survival.  Filter beds stocked with juvenile worms produced 300–400 grams of harvestable worms per square meter of filter in 16 weeks.


The study shows how marine worms can be reliably produced in simple, low-maintenance sand filters and discusses how they can be integrated into wastewater treatment systems at marine shrimp farms.

Tilapia Growth Hormone Helps Shrimp PLs Grow 42% Larger


From Abstract: In this study, tilapia growth hormone (GH) was used to determine the presence of a presumed protein with GH receptor-like functions in the hepatopancreas of Penaeus vannamei and to evaluate its effect on growth of P. vannamei postlarvae.  The receptor assay was performed using brush border membrane vesicles (BBMV) from the hepatopancreas of P. vannamei.  The shrimp postlarvae treated with tilapia GH were 42.4% heavier and 5.2% longer than the control group (P < 0.05).  Content of soluble proteins per milligram of weight was 1.33 times higher in the GH-treated animals than control animals.  No significant differences in survival rates were detected among the experimental groups.


In conclusion, the researchers say: A GH receptor-like protein was detected on hepatopancreas vesicles of P. vannamei.  It was established that tilapia GH was able to enhance the growth of shrimp postlarvae.  To our knowledge, this is the first report to demonstrate an interaction between a vertebrate growth hormone and a GH receptor-like protein of a crustacean.

Anaerobic Sludge Digesters for Intensive Shrimp Farms


Intensive recirculating aquaculture systems produce high volumes of sludge.  A reduction in sludge mass would reduce the cost of disposal and minimize the potential of environmental damage.  Recently, anaerobic digestion has been suggested as a way to deal with the sludge that develops in intensive aquaculture systems.  Anaerobic digesters not only reduce the amount of sludge, they also lower the costs of treating water when compared to traditional treatment methods—and they produce useable biogas as a byproduct.  This review summarizes what’s known about anaerobic digesters and compares various digester technologies.


Anaerobic digestion (AD) is commonly used for the stabilization of municipal, industrial and agricultural wastes.  It works by biologically degrading organic matter in an oxygen-free environment.  It’s a natural process, carried out by facultative and obligatory anaerobic bacteria.  Commonly, the digestion is practiced at one of three temperature regimes: thermophilic (45–65 °C), mesophilic (25–45 °C) and psychrophilic (10–25 °C).  AD has long been used for the stabilization and reduction of wastewater sludge (but not aquaculture sludge), mainly because of the simplicity of the operation, reduced sludge generation, production of biogas and high loading rates.  Sludge undergoes considerable changes in its physical, chemical and biological properties during AD.  Under ideal conditions, the ultimate products of this process are biogas composed of methane and carbon dioxide with small levels of hydrogen sulfide and ammonia.  Salinity, pH, mineral composition, temperature, loading rate, hydraulic retention time, the carbon-to-nitrogen ratio and volatile fatty acid content influence the digestibility of the sludge and biogas production.


There are four main stages in the AD process: hydrolysis, fermentation, acetogenesis and methanogenesis.

Florida—Town Decorates Itself with Shrimp Statues


In an event called “Shrimp Expression”, fiberglass shrimp sculptures, each whimsically decorated by a local artist, have been placed around downtown Fernandina Beach and on Amelia Island.  In September 2010, the shrimp will retreat to a temporary home to rest and get freshened up, and then, on October 16, 2010, they will be auctioned off.  The event is sponsored by Micah’s Place, which creates awareness of domestic violence and supports local artists and tourism.  You can view all of the shrimp statues at the Shrimp Expression website.


Information: If you have an interest in bidding on one of the shrimp statutes, contact Kelly Monti, Project Coordinator at Micah’s Place (phone 1-904-491-6364, extension 100, email projectcoordinator@micahsplace.org).


Jeff Peterson, Director of Quality Control at the Global Aquaculture Alliance, who lives in Fernandina Beach, forwarded this picture, with this comment: “Not very good anatomically...but good fun and for a good cause.”

Michigan—Aeration Technology


Dissolved oxygen (DO) is a limiting factor in aquaculture production systems.  Utilization of continual real time dissolved oxygen monitoring devices in intensive rearing systems can help reduce risk of catastrophic loss and provide potential biological monitoring and control mechanisms designed to maximize production potential.  While DO measuring instruments are fairly common in the aquaculture industry, widespread use of continual monitoring systems is constrained by various factors.  Here, the researchers report on the development of a new optical dissolved oxygen sensor using fiber optic technology and a stable inorganic indicator embedded in an oxygen permeable matrix designed specifically for use in aquaculture systems.  Reliable, continual device operation is enabled by the inherent thermal stability of the optical indicator and its immunity to photo bleaching.


Field trial data show the device easily tracked extremely rapid DO fluctuations exceeding 2-3 mg/l during routine operations such as system maintenance and feeding, even under moderate loadings.  Using two sensors, researchers were able to discern algal photosynthesis and respiration in comparison to mixed water column dissolved oxygen concentration in an outdoor pond.  In separate experiments, they have demonstrated the ability to carefully track diurnal variations in both flow-through raceway and outdoor pond production systems.


Based on observations made in field trials, the researchers explore theoretical applications of continual real-time DO monitoring technology designed specifically for optimizing aquaculture production through aeration and feeding strategies.  They conclude with recommendations for overcoming various factors that appear to be constraining use of these techniques in the aquaculture industries.

NaturalShrimp is a small, intensive, indoor farm in La Coste.  In a two-minute video about the farm, Doug Ernst, Ph.D., vice president of research and development, said, “We control water temperature so that it’s always like summer conditions for the animal.”


Ernst said the company began nine years ago and has had a lengthy learning process.  The original facility now serves as a water treatment center after it failed to provide the proper conditions for raising Pacific white shrimp.  There’s no how-to book on shrimp farming and just about everything in our current facility has been custom-made to meet our needs, including some trade secrets in the growout tanks.


“Our ingredients for growing shrimp are fresh water, sea salt and oxygen,” said Ernst.  “We use a premium shrimp feed and a proprietary blend of beneficial bacteria.  Our innovation is in the synthesis of how we put all that together to make something that will grow shrimp....”


With much of its 37 acres still covered in wild grass, NaturalShrimp hopes to expand its shrimp farming facilities.


“The goal here is to act as a technology development center and to create a technology that’s transferable to any region,” said Ernst.


The company has a partner in Spain constructing a similar farm north of Madrid, said Ernst.

Washington DC—Food Safety Legislation


Every day, about 200,000 Americans are sickened by contaminated food.  Every year, about 325,000 are hospitalized by a food-borne illness.


If the Senate fails to pass the food safety legislation now awaiting a vote, tens of thousands of American children will become needlessly and sometimes fatally ill.


Almost one year ago, the House of Representatives passed the Food Safety Enhancement Act with bipartisan support.  In November 2009, the Senate Health, Education, Labor and Pensions Committee unanimously approved a similar bill, the FDA Food Safety Modernization Act.  This legislation would grant the Food and Drug Administration, which has oversight over 80 percent of the nation’s food, the authority to test widely for dangerous pathogens and improve the agency’s ability to trace outbreaks back to their source.  Most important, it would finally give the agency the power to order the recall of contaminated foods—and to punish companies that knowingly sell them.


The bill is supported by an unusual set of advocacy groups: the American Public Health Association, Consumers Union, the Center for Science in the Public Interest, the United States Chamber of Commerce and the Grocery Manufacturers Association, among others.  Last week, a poll for Consumers Union found that 80 percent of Americans want Congress to empower the FDA to recall tainted foods.


You’d think that a bill with such broad support, on a public health issue of such fundamental importance, would easily reach the floor of the Senate for a vote.  But it has been languishing, stuck in legislative limbo.  If it fails to gain passage by the end of this session, Congress will have to start from scratch next year.


Food processors reluctant to oppose the bill openly will be delighted if it dies a quiet death.  That’s because, right now, very few cases of food poisoning are ever actually linked to what the person ate, and companies that sell contaminated products routinely avoid liability.  The economic cost is, instead ,imposed on society.  And it’s a huge cost.  According to a recent study sponsored by the Pew Charitable Trusts, the annual health-related cost of food-borne illness in the United States is about $152 billion.


The bill very clearly instructs the Food and Drug Administration to focus its enforcement efforts on plants that pose the greatest risk of causing large-scale outbreaks.  The bill’s wording can still be clarified so that mom-and-pop producers are not threatened by heavy-handed government regulations.

Controlling Foreign Matter in Exported Shrimp


Vietnam’s Association of Seafood Exporters and Producers (VASEP) has embarked on a new campaign that, in effect, says “No Foreign Matter in Our Shrimp”.  The campaign will target everyone in the production chain from farms right through to processors and shippers.  VASEP will keep a list of companies that adhere to the motto.
