Pangasius farmed in the Dominican Republic? True story. Value Aquaculture, with partners hailing from Germany and Chile, is trying to get U.S. buyers to take a fresh look at the Mekong catfish species. 

Vietnam’s pangasius industry captivated the global seafood industry, environmental organizations and the mass media. A scientific look at harmful substances detected in exported fillets and the reporting of the associated health risks through the media finds wide disparities. 

Western nations consume considerable quantities of pangasius, yet its aquaculture in tropical regions of the hemisphere has not followed. Several countries have approved pangasius aquaculture, and to date no negative environmental impacts have been observed. 

In Europe, most frozen white fish fillets operate in an undifferentiated market. Although differences in quality and processing affect pricing, there is also competition across species and exporting countries. Analysis showed that prices for tilapia from the leading exporter China were not affected by any competitor, but pricing for tilapia from other countries was highly related. Low Pangasius prices affected the market share of tilapia, which may help explain why Pangasius is a most popular fish in the European Union. 

Trials show that supplementation with amino acids could reduce protein levels from a typical 28 percent to 23 percent in pangasius diets. 

As examined in various studies, potassium diformate can improve the growth and health status of pangasius when the dietary acidifier is included in feed. 

Phytogenics comprise a class of plant-derived feed additives that improve animal performance. They have been shown to exert multiple positive effects in fish and shrimp, including improvement of feeding efficiency and digestion, reduction of nitrogen excretion and improvement of gut flora and health. 

Many consumers look for an eco-label or rely on a trusted retailer or restaurant to identify sustainable seafood. Certification programs convey this assurance by providing consistent information about the origins, food safety and environmental credentials of seafood. 

In a laboratory trial, juvenile pangasius given a diet with 0.2 percent potassium diformate (KDF) had better weight gain, feed conversion and survival than fish that did not receive KDF. 

Fish supply is a food security priority in Bangladesh. There is potential for the culture of non-native fish species to meet its growing population's needs. 

When the price for a newly introduced seafood product was unknown to consumers, a study found, price consciousness affected purchase intentions among consumers with high levels of general product category knowledge. 

In a study of Norwegian consumers asked to evaluate pangasius fillets, the extrinsic cues corporate social responsibility, endorsement and country of origin had different effects on evaluative variables. 

In modifying its infrastructure and related pond management, QVD Aquaculture uses floating water plants to remove nitrogen and phosphorus from the discharge water. Sludge pens capture sludge at ponds for later reuse. 

In a study with pangasius, dietary administration of a blend of botanical extracts improved performance, reducing intensity of gill parasite infestation. 

Authors developed a lexicon of sensory properties for pangasius fillets and examined the sensory characteristics of raw fresh and frozen catfish fillets as predictors of the sensory qualities of cooked catfish.
