Ecuadorian shrimp farming: A success story

: 5525

Located between Colombia and Peru on the Pacific cost of the South American continent, Ecuador is a small Latin American country, with only 277,000 square kilometers of land and 2,200 km of coastline. Nevertheless, Ecuador is one of the world’s major players in farmed shrimp production, especially if we look at the shrimp production ratios relative to the land surface or to the length of coastline of the considered countries. Shrimp farming in Ecuador started in 1969 with the extensive [...]

A look at various intensive shrimp farming systems in Asia

: 4473

Commercial implementation of biofloc and RAS production systems help control shrimp farming diseases Intensive shrimp farm in Bali, Indonesia producing shrimp in a biofloc system (Taw and Setio, 2014). Before the mid-1990s, the major diseases affecting the farmed shrimp industry were of bacterial origin. But in Asia and from late 1994, the appearance of various,… See more at https://www.aquaculturealliance.org/advocate/intensive-shrimp-farming-asia/

Bioavailability of crude protein and lipid from biofloc meals produced in an activated sludge system for white shrimp, Litopenaeus vannamei

: 2941

ABSTRACT The present study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C). The sludge system operated by chemical and organic fertilization three times per week. Sampling of bioflocs occurred every two days during 81 days. To evaluate digestibility, each type of biofloc meal was incorporated into a reference diet (REF) at 300 g/kg. Another diet [...]

High-density shrimp producer wins innovation award

: 4830

The Global Aquaculture Alliance (GAA) will recognize a farmed shrimp producer in Brazil as a leader in innovation. Camanor’s high-density, land-based facility recycles water for multiple production cycles while preventing environmental degradation and the use of chemicals or antibiotics. At GAA’s annual GOAL conference in Vancouver next week, Camanor Produtos Marinhos Ltda. Director Werner Jost will accept the Preferred Freezer Services Global Aquaculture Innovation & Leadership Award for AquaScience®, what he calls a “new concept in sustainable shrimp production” operating [...]

Aquamimicry: A revolutionary concept for shrimp farming

: 6657

View of a grow-out shrimp pond implementing the Aquamimicry production approach. Technology has been met with success worldwide by balancing natural plankton. The prevalence of numerous diseases that affect the shrimp and prawn aquaculture industry has promoted the development of various health management strategies. Some include greater biosecurity and sourcing of specific pathogen free animals, and in more extreme cases, using chemicals and antibiotics. However, because of the nature of open pond aquaculture, where most farmed shrimp is produced globally, it is [...]

Testing an intensive shrimp hatchery system using biofloc technology

: 4483

The hatchery phase is a critical and complex first step in the commercial farming of Pacific white shrimp, and constant attention is required to produce shrimp postlarvae of the best quality possible. The use of biofloc technology (BFT) is increasing in the aquaculture of many commercially-important aquatic species. BFT is used to intensify production and to minimize or prevent the exchange of culture water, with a consequent reduction in potential pathogens and the discharge of nutrient-rich effluents into the environment. The [...]

CIBA’s new eco-friendly ‘Biofloc’ technology for shrimp farmers

: 3739

CHENNAI: To help India retain its market share in global shrimp export and neutralise disease threat, Central Institute of Brackishwater Aquaculture (CIBA) is popularising ‘Biofloc’ technology, which is eco-friendly and sustainable. CIBA scientists say commercial interest in biofloc technology is threefold. It provides high productivity, low feed-conversion ratios (FCRs) and a stable culture environment. Also, with emerging bacterial and viral problems coupled with rising costs for energy, biofloc appears to be an answer for sustainable production at lower cost. Marking a [...]

Plankton Communities In Shrimp Monoculture, Integrated Biofloc System

: 2141

Summary: The authors performed a study to assess the plankton community in an integrated biofloc system with Pacific white shrimp, Litopenaeus vannamei, and red algae, Gracilaria birdiae. Once a week over seven weeks, phytoplankton were sampled in three tanks with monoculture of shrimp and nine tanks with integrated biofloc systems containing shrimp and algae. Shrimp survival was above 89% during the experiment. Feed conversion and final shrimp weight were better for the biofloc system than the monoculture system. A variety [...]

Escape from EMS/AHPND at SGIC

: 5439

How this is achieved is through management of culture systems, biosecurity, avoiding use of chlorine for pond and reservoir water disinfection and thorough clean-up of hatchery. Dr Boonsirm Withyachumnarnkul at Centex Shrimp, Mahidol University said that with widespread destruction of crops with early mortality syndrome (EMS) in vannamei shrimp farming, some farms in Thailand have returned to farming the black tiger shrimp in 2013. The Shrimp Genetic Improvement Center (SGIC), Surat Thani, Thailand has largely escaped being infected with the bacteria causing [...]

Marine Shrimp Biofloc Systems: Basic Management Practices

: 3040

This publication summarizes basic management practices for the majority of farmers raising marine shrimp (Litopenaeus vannamei) in Indiana, US, based on the most current literature available, writes Robert Rode, Purdue University. Over the past few years an increasing number of marine shrimp enterprises have started up in Indiana. These operations garner attention because of their lower capital costs, their variable scale of production, and shrimp’s high market price. Based on feedback from a 2014 meeting with Indiana shrimp farmers, it appears that both novice [...]
