Introduction Cyanobacteria, blue-green algae, harmful algae, and toxic algae are words that can confuse people who are trying to decide on pond water safety. Certain algae can cause serious problems when they become very abundant in drought, hot weather, unusual rainfall patterns, or after nutrient accumulation in pond water. Fortunately, most ponds do not experience toxin problems or dense algal blooms. Watching for the warning signs that lead to toxic algal bloom development...

A phytobiotic was able to reduce Vibrio counts in intestine and hepatopancreas leading to an increase in survival and better health. Shrimp farming is growing very fast in recent years, due to the high profit margins which present a good opportunity for those with interest in this sector. In Asia the production of Pacific white shrimp (Litopenaeus vannamei) was more than 3 million tonnes in...

Shrimp farming currently yields about 800,000 mT of shrimp a year. The industry has grown phenomenally in the past 25 years considering that farmed shrimp production in the early 1970s was less than 10,000 mT. The industry grew exponentially in the 1980s. Its further growth was arrested in the 1990s when a number of disease problems surfaced. While bacterial and viral diseases have been common in the industry since its inception, the scale of destruction caused by three specific viral disease...

the aquaculture industry has developed significantly over recent decades and is, today, one of the fastest-growing food production sectors in the world. One of the most important problems that affect aquaculture is the appearance of infectious diseases. Among bacterial diseases affecting cultured salmonid fish, Bacterial Cold-Water Disease, caused by Flavobacterium psychrophilum, produces high mortality and morbidity and consequently, economical losses...

An increased palatability of feed when coated with a specific probiotic was discovered in this trial. The marine shrimp, having poor sight, need to recognise their environment by other senses, i.e. tactile, gustatory and olfactory. The olfactory sense is important because it will dictate whether a shrimp is attracted to an artificial feed. As a consequence, commercial feed manufacturers formulate their feed for their...

Aquaculture is concerned with 'the propagation and rearing of aquatic organisms under complete human control involving manipulation of atleast one stage of an aquatic organism's life before harvest, in order to increase its production'. Fish catches from the marine environment have been steadily declining in many parts of the world due to over-exploitation and pollution, making many people turning to aquaculture to improve the food production and to contribute for economic development....

The ongoing outbreak of early mortality syndrome/acute hepatopancreatic necrosis (EMS/AHPN) has had dramatic impacts on shrimp producers in affected countries in Asia and Mexico. Following reports of the disease being associated with broodstock management – for example, through the use of contaminated polychaetes – there has been a renewed focus on larval quality. Investing in quality larvae fits well in the holistic...

Understanding the microbial ecological process in ponds and in the shrimp intestinal tract is vital to maintain and optimize productivity without prophylactic use of hazardous substances. The maintenance of good water quality and the control of disease are closely linked to managing the communities of microbes and phytoplankton. ...

In a presentation during a session on marine fish and larval rearing innovation, at the Australasian Aquaculture 2008, Brisbane we discussed that Bacillus probiotics are proving very beneficial for fish larval rearing in European and Asian hatcheries, The strains of Bacillus were checked for safety and selected for their ability to inhibit directly bacteria pathogenic to fish, produce exoenzymes to improve digestion and degrade waste products and to grow under a...

World tilapia production has risen from 830,000 tonnes in 1990 to 1.6 million tonnes in 1999 and again to 2.5 million tonnes in 2005 (Josupeit, 2007). China is the world's largest producer of the tilapia, producing over one million tonnes in 2005, followed by Egypt (300,000 tonnes), Indonesia, Philippines (200,000 tonnes each) and Thailand (100,000 tonnes). By 2010, world tilapia production is expected to reach 3.5 million tonnes (Josupeit, 2007). Risks from diseases With...

From both nutritionist and aquaculturist points of view, our aim is to sustainably produce aquatic food with superior sensory properties and high cardioprotective properties. The reason is that although preventable, cardiovascular diseases (CVDs) remain the top global cause of death and stroke. The prevention of atherosclerosis is, therefore, a major objective of modern medical and biochemical investigations into the...
