Country Reports


Australia
Cyclone Hits Queensland Shrimp Farms

Flooding from Cyclone Larry has devastated shrimp farms in Queensland, which supplies 40 percent of Australia's shrimp. Scott Walter from the Australian Prawn Farmers Association says there have been huge losses due to floods and loss of power. Walter said: "We need power to run the aerators in our ponds, which keep the oxygen levels up to a point where the prawns are capable of basically growing and surviving. So if we lose the ability to oxygenate our ponds we'll lose our crops, and if the freezers go down for too long and the seals are broken, the temperatures will rise and we'll have to destroy the stock because it'll no longer be safe for food."

Brunei (a small nation on the north coast of Borneo)
"Rostries"

According to Senior Fisheries Officer Awg Sabri, shrimp farming was introduced to Brunei in early 1994. At present, he said, there are 13 farms with a total area of 230 hectares farming Tiger shrimp and "Rostries" [Penaeus stylirostris, remnants of a Super Shrimp project]. In 2005, production was 394 metric tons, sold in local markets and exported to the USA, Taiwan, Japan, Malaysia and Singapore.

The Fisheries Department has opened a new, 459-hectare area in Tutong to shrimp farming. The offer is open to local entrepreneurs and foreign investors. Proposals must be submitted to the department by April 25, 2006.

Namibia (Southwest Africa)
Alec Forbes

Dr. Alec Forbes, says, "Shrimp production is gaining momentum around the world. We have some very big players who are looking at Namibia to invest."

Since 2004, Dr. Forbes has been working for Namibia's Ministry of Fisheries and Marine Resources under the Commonwealth Fund for Technical Cooperation (CFTC). The fund assists member countries with development projects at the request of their governments. The CFTC project with Dr. Forbes was set to be completed in 2006, but it now has been extended until 2008.

Dr. Forbes and his team want to increase Namibia's shrimp production. The country is too cold for tropical techniques, so Forbes is looking at greenhouse culture as a way to extend the growing season.

Alltech's "NuPro" Replaces Fishmeal

Alltech Inc., a global feed biotechnology company, markets a product called "NuPro", designed to replace the fishmeal in aquaculture feeds. Developed by Drs. Ewen McLean and Steven Craig, researchers at the Virginia Tech Aquaculture Center (Virginia, USA), it's yeast-based and organically certifiable.

From June to October 2005, NuPro was tested at the Organic Aquaculture Institute (below, a nonprofit organization that conducts research on organic fish and shrimp farming) with Penaeus vannamei maintained under organically certified protocols.

A microbial food chain was encouraged in the ponds. Ponds did not receive prepared feed during the first 30 days of the trial; they were fertilized with composted manure applied at a rate of 51 kg/ha every two weeks, a protocol that was continued throughout the trial. On July 16, 2005, ponds began receiving commercial feeds. Initially, feed was applied at 18 kg/day as two equal feedings, then on October 1, it was lowered to one feeding of 14 kg/day.

Ponds receiving the NuPro-based feed had equivalent growth to those fed the traditional, fishmeal-based diet. Percentage increase in weight from initial values and survival for the NuPro ponds was 296, 269 and 275% and 78, 76 and 85%, respectively. Percentage increase in weight from initial values and survival for the control pond were 305% and 80%.

Feed conversion ratios averaged 0.52 for the NuPro fed ponds compared to 0.51 for the shrimp fed the commercial fishmeal-based feed. Overall production for the trial was approximately 10,900 kg of harvested shrimp with a feed input of 5,450 kg.

Thailand
Tim Flegel-SPF Not Sufficient

In the February/March 2006 issue of the Global Aquaculture Advocate, Dr. Timothy Flegel, a professor at Thailand's Mahidol University, concludes a two-part discussion on the dangers of translocating shrimp with the following recommendations:

Given the propensity of shrimp, crustaceans and other arthropods to carry viral infections, it is reasonable to suggest that the International Council for the Exploration of the Seas (ICES) guidelines be modified and closely followed to guard against the possibility of introducing new viral pathogens. It is not sufficient to certify the exotic animals as "pathogen-free" from a list of known pathogens with available diagnostic tests. There is additional danger from previously unknown viruses or variants of known viruses for which no assay methods exist.

Given the experience with IHHNV in Penaeus monodon, it would seem prudent to add to the ICES guidelines a special requirement that native species of shrimp and other economically important crustaceans be included as cohabitants in the quarantine phase of the importation process. This would guard against the unintentional transfer of well-tolerated, unknown pathogens from the exotic hosts to the local species.

As shrimp aquaculture expanded globally, exotic species of shrimp were shipped legally and sometimes illegally around the world. The unseen diseases some of the shrimp carried were consequently spread to new areas and species. More complete and consistent inspection, quarantine and diagnostic measures could help alleviate the problem of diseases spread by animal shipments.

Weather Stops Shrimp Farmers

Pokklong Kerdsuk, chairman of the Krabi Shrimp Farming Club, says that rain, heat and humidity during this year's dry season have forced about 50% of the shrimp farmers to shut down along the Andaman Sea, where about 300 hectares of ponds are spread over five districts.

Zeolite

The purpose of this study was to evaluate the characteristics of 25 different zeolite products purchased from shrimp supply stores in Thailand in June 2003.

None of the products appeared to be of much value for ammonia removal. Therefore, there is no reason to recommend one product over the other. The best recommendation is to refrain from using zeolite for ammonia removal from pond waters.
