    S. Florida-based Regal Springs Tilapia is the king of fresh tilapia

S. Florida-based Regal Springs Tilapia is the king of fresh tilapia

Special to the Miami Herald

Magdalena Wallhoff has quite a fish story to tell. But this is about the one that didn’t get away.

Born in Switzerland and raised partly in Indonesia, Wallhoff was 7 when her father, Rudi Lamprecht, started a fish farm in Java in 1988.

Twenty-five years later, Regal Springs Tilapia, now headquartered in Miramar, is among the largest single producers of farmed tilapia in the world. In 2014, the company estimates it will supply 60 percent of the fresh tilapia sold in the United States, about 36 million pounds. Regal Springs also holds about 8 percent of the market share of frozen tilapia sold in the U.S., about 40 million pounds.

    Risks Associated with Using Methyl Testosterone in Tilapia Farming

Risks Associated with Using Methyl Testosterone in Tilapia Farming

Despite widespread use of the androgen 17α-Methyl Testosterone (MT) in tilapia farming, the implications of tilapia hormone treatment in relation to human health and the environment have not been well articulated to the fish trade, or the general public. The purpose of this white paper is (a) to explain clearly why MT is widely used by the producers of farmed tilapia; and (b) to demonstrate why there are no risks to consumers, and no known risks to producers or the environment, provided the recommended best practices for MT use in aquaculture are followed. These best practices are described, so that tilapia dealers can ensure that their suppliers are taking the necessary steps to protect consumers, fish farm workers and the environment.

The Feinstein Group Takes Over Fresh Catch

The Feinstein Group Takes Over Fresh Catch
March 4, 2014

The Fresh Catch Tilapia Farm in La Democracia will be going back into operation and the man at the helm will be developer Mike Feinstein. Feinstein told 7News that the deal was finalized last Friday and his group will bring everything back into operation and expects to be harvesting in about a year.


That's a dramatic change for the company that's been in receivership after the First Caribbean Bank foreclosed on it in 2010. That was under the Mena group. The Mena's had financing difficulty but still they were doing 4.3 million pounds of fish at their peak in 2008 - and Feinstein told us he is confident he can bring it back.


Feinstein says he will be rehabilitating the farm and within three to four weeks he will be importing fish and putting them back into the ponds.


And so what's the price? Well, Feinstein is sure to be getting it on the cheap at a distress price. At its inception, before expansion the farm was valued at 36 million Belize dollars and in 2011, the Mena's tried to bring it back with a 15 million dollar buyout form the bank, which was said to be a price of 38 cents on the dollar. That attempt failed.


Feinstein told us that pond rehabilitation started yesterday. The buyout is seen as a major shot in the arm for a fish farming industry that had died off.

Mexican tilapia farm to supply West Coast

Mexican tilapia farm to supply West Coast
By SeafoodSource staff

American seafood farming company Tropical Aquaculture Products has announced a partnership with a new tilapia farm in Mexico.

The company has begun operations at Acuicola Gemso, producting tilapia in a cage system in the Novillo Reservoir, east of Hermosillo, Sonora, Mexico. The company expects a new processing facility to open in early 2015.

Gemso has been producing tilapia for nearly five years, and claims to not use any preservatives or gases that may alter, extend or prolong natural color or shelf life.

Tropical Aquaculture, in a statement, said the company is planning for its first audit for the Global Aquaculture Alliance's Best Aquaculture Practices certification. The company expects to have the certification by May of 2014.

Tropical Aquaculture expects to be able to use the farm to supply Tilapia to the U.S. west coast. - See more at:

    China’s tilapia price rebound draws aquaculture giant to invest

China’s tilapia price rebound draws aquaculture giant to invest

A turnaround in the country’s tilapia pricing has brought one of China’s biggest aquaculture firms to ramp up its tilapia breeding and processing capacity. Known more for its prawn production and processing, Zhanjiang Guolian Aquatic Co. is ramping up its tilapia seedlings business in a large new facility that has come online in Wuchuan, in the company’s home province of Guangdong. This follows a greatly improved performance by the Chinese tilapia sector in 2013.

Tilapia cultivators were losing money in 2012 as weak demand and disease contributed to a poor outlook. That in turn forced a lot of small aquaculture players to exit the tilapia sector. Interviewed by the local press this week, breeding manager at Guolian’s tilapia base in Wuchuan, Zhao Honglei explained that in 2013 prices grew solidly and demand for fingerlings increased greatly.

“A lot of cultivators exited, they gave up tilapia breeding. There was an enormous fall in tilapia output and a growing gap in supply for processors, so now we are producing tilapia again.”

Data published by the Chinese agriculture ministry shows farm gate prices for tilapia surged from CNY 4.7 (USD 0.77åç, EUR 0.56) per 500 grams (g) (for fish of .5 kilograms (kg) and heavier, a common factory grade) in mid-2013. By the end of 2013 those prices surged to CNY 5.3 (USD 0.87, EUR 0.64) and CNY 5.4 (USD 0.89, EUR 0.65) as factories struggled for a stable supply of tilapia for processing.
Local analysts watching China’s seafood sector have welcomed Guolian’s move into tilapia as a way of insulating the firm against volatility in global shrimp markets.

“The coming online of Guolian’s tilapia breeding project is a good move to spread risk,” explained Wang Fenghua, analyst at Hongyuan Securities, which [...]

    Incorporation of Omega-3 Fatty Acids in Nile Tilapia Fed Chia Bran

Incorporation of Omega-3 Fatty Acids in Nile Tilapia Fed Chia Bran


This study evaluated the effect of the inclusion of chia bran in the diet of Nile tilapia on the composition of n-3 fatty acids (FA). Omega-3 fatty acids provide health benefits such as reducing the risks of coronary heart disease, hypertension and inflammation, and the precursor alpha-linolenic acid is considered strictly essential because it cannot be synthesized by humans, therefore must be ingested. Tilapias grown in tanks for a period of 45 days were treated with diets supplemented with either soybean oil (TI) or chia bran (TII). Proximal composition analysis of the feeds showed no significant difference. Feed FA quantification showed that the chia diet (TII) had a higher alpha-linolenic acid (LNA) content. A significant increase was observed in the concentrations of LNA (8.38–81.31 mg 100 g−1 fillets), eicosapentaenoic acid (1.12–1.56 mg 100 g−1 fillets) and docosahexaenoic acid (19.55–26.55 mg 100 g−1 fillets) in tilapia fillets between 0 and 45 days for TII. Total lipids at 45 days under TII were fractionated into neutral lipids (67.66 %) and polar lipids (18.90 %). Thus, dietary supplementation with chia bran contributed to raising the nutritional quality of Nile tilapia fillets.

Introduction to Tilapia Sex

Introduction to Tilapia Sex-Determination and Sex-Reversal
Kevin Fitzsimmons
University of Arizona
One of the basic factors of tilapia aquaculture is that male fish grow bigger and faster than the females.  Also, in order to avoid unwanted spawning in a production unit, all-male populations are preferred.  There are several methods used to skew sex ratios and increase the percentage of males in a population.


The first method developed was to simply cull through a population, discard the females and keep the males.  This system is obviously wasteful and inefficient.  In the 1960’s and 70’s,  Israeli scientists discovered that certain hybrid crosses resulted in skewed sex ratios favoring males.  There are several theories regarding the genetic factors involving the number and location of sex genes on particular chromosomes.  The use of hybrid crosses is still one of the primary methods of producing mostly male populations.  The drawback to this method is that two separate broodlines must be maintained.  The crossing must be done very carefully and meticulous records should be kept to insure that the parent species are kept pure.  Also, usually only one sex from each species is used for any particular cross because the reciprocal cross (using the other sex from each species) is not as successful.  Another problem is that the number of young produced is rarely as high as a single species spawn.  Therefor, to maintain a commercial scale hatchery will usually require significant resources and staff.


The more common method of generating mostly male populations is through the use of steroids fed to sexually undifferentiated fry.  Newly hatched tilapia are still developing their gonads.  Even though they are determined genotypically their phenotype, or morphological characteristics can still be altered.  By exposing the fish to forms of [...]

Introduction to Tilapia Nutrition

By Kevin Fitzsimmons
University of Arizona
One of the great advantages of tilapia for aquaculture is that they feed on a low trophic level.  The members of the genus Oreochromis are all omnivores, feeding on algae, aquatic plants, small invertebrates, detrital material and the associated bacterial films.  The individual species may have preferences between these materials and are more or less efficient depending on species and life stages in grazing on these foods.  They are all somewhat opportunistic and will utilize any and all of these feeds when they are available.  This provides an advantage to farmers because the fish can be reared in extensive situations that depend upon the natural productivity of a water body or in intensive systems that can be operated with lower cost feeds.
In extensive aquaculture, the fish will be able to grow by eating algae and detrital matter and the farmer can grow more fish in a given area because the fish are depending directly on the primary productivity of the body of water, primary consumers.  Fish which feed on a higher trophic level, eating larger invertebrates or small fish, are secondary consumers and a system can only support a fraction of the biomass of secondary consumers compared to primary consumers.
In intensive systems, tilapia have the advantage that they can be fed a prepared feed that includes a high percentage of plant proteins.  Carnivorous fish require fish meal or other animal proteins in their diets, which in general are more expensive than plant proteins.  Nutritional studies which substitute plant proteins supplemented with specific amino acid supplements may lower costs, but still not to the level that can be achieved with tilapia diets.
Complete diets are used in systems that cannot provide any [...]

Introduction to the Genetics of Tilapia

By Thomas D. Kocher
Department of Zoology & Program in Genetics
University of New Hampshire
Basic tilapia genetics
We are at an early stage in the genetic domestication of tilapia. During the approximately 40 year history of intensive culture, the genetic resources of tilapia have been poorly managed. The genetic problems now manifesting themselves are of several kinds. First is the loss of pure species through mismanagement of interspecific hybridization (McAndrew 1993), a technique which has been used to produce all-male fry which have a higher growth rate in production systems (Hickling 1960; Hulata et al.1983). One popular commercial strain is thought to contain genes from as many as four species (McAndrew et al. 1988). A second problem is high levels of inbreeding depression. Primary collections of wild broodstock frequently consisted of a small number of individuals. These were serially distributed, so that genetic problems have been passed from country to country, and farm to farm. Eknath et al. (1993) compared four strains farmed in the Philippines with four strains newly isolated from wild populations in Africa. The best performing strains were those most recently isolated from nature, consistent with the idea that domesticated strains suffer from inbreeding depression (Tave and Smitherman 1980; Hulata et al. 1986; Teichert-Coddington and Smitherman 1988). A survey of 18 microsatellite DNA markers in several commercial strains found some strains with heterozygosities less than 10% of that found in wild strains (Kocher et al., unpubl.). In addition to inbreeding, it is likely that negative selection for growth rate has occurred during the propagation of many stocks. Finally, there is evidence for contamination of genetically improved strains by introgression from feral species (Macaranas et al. 1986).
In recent years attention has focused on a single [...]

    Buhl Fish Farm Sells Live Seafood Directly to Local Consumers

Buhl Fish Farm Sells Live Seafood Directly to Local Consumers

Article from – original link at end of article.
BUHL • Oysters plucked from the cold waters of Puget Sound are alive in the sagebrush-covered hills just outside Buhl. Just find the sign that reads “shrimp and oysters” and follow the arrow to Don Campbell’s First Ascent Fish Farm.

Campbell has owned First Ascent since 1986. Over the years the farm’s products have diversified to compete in the changing landscape of aquaculture. The farm started out raising trout and switched to catfish. Then when the company could no longer compete with catfish imported from Vietnam it switched to tilapia, a fish found in the warm waters of Africa and the Mediterranean.

But no matter the type of fish swimming in First Ascent’s tanks, Campbell’s wholesale and retail customers get what they want no matter where they are — even if that means transporting live tilapia 10 hours to Seattle by truck.

“We ship 52 weeks out of the year,” Campbell said.

Every Tuesday and Thursday, workers load up 2,000 pounds of tilapia that travel 2,700 miles to 14 family-owned stores and restaurants in Seattle. First Ascent does not deliver in Idaho because there are few restaurants and stores with tanks, but locals can buy the tilapia by visiting the farm.

Live tilapia is in demand, said Gary Fornshell, University of Idaho aquaculture extension educator. “Tilapia is the fifth most consumed seafood in the U.S.”

Campbell’s business is not the only fish farm in Idaho that live-hauls its product; Fornshell estimated there are about five fish farms that sell live fish to local customers in the Magic Valley. But First Ascent is one of the few family-owned farms in Magic Valley that deal strictly with live seafood and, Fornshell believes, the [...]

Press Release

Announcing the formation of the America’s Tilapia Alliance (ATA)

The America’s Tilapia Alliance (the “ATA”) was formed in September 2013 by a group of US and foreign tilapia enthusiasts. A previous entity called the American Tilapia Association is in the process of dissolution. The former entity was organized in 1996. Since 1996 the industry has evolved and tilapia production has boomed worldwide. Fish farmers are not the only entities involved to create a healthy and expanding tilapia industry. The stakeholders include academia, pharmaceutical companies, feed suppliers, equipment manufacturers, seed and genetic providers, various laboratories, consulting and technology transfer companies, distributors, sales and marketing companies, and grocery and food service companies. All these actors have a role to play before the product ever gets to the end user – the consumer. The establishment of the new ATA will enable the additional stakeholders to become members of the expanded organization and enable them to add value to the industry.

The ATA’s initial objective is to expand the membership by having as members a variety of tilapia aficionados who invest time and or money within the tilapia industry. This brain trust of membership will offer their experience, contacts and financial support to protect and promote an improved image of tilapia. What needs to be developed by this collective are proactive and reactive programs that promote and protect the industry. To be effective within our budgets and means, targets have to be well coordinated by ATA members, Directors and committees.

To create interest and focus, the ATA will rely heavily on web based communication. The ATA expects to develop websites, and chat forums among the various groups that contribute to the tilapia industry. The ATA has solicited the [...]
