Center for Fisheries Technology Innovation (CFTI) Will Serve to Promote Peruvian Aquaculture

By Yojaira Paternina Cordoba*

Lima, Peru  Jan. 28, 2015.  The Peruvian government wants the CFTI to serve as an additional agency to promote aquaculture within the country, increasing sales, productivity and quality of aquacultured products, both domestically and in international markets.  The Center will support technology transfer, training and technical assistance for businesses and producers in supply and value chains, with a special emphasis on aquaculture development.  

In this regard, Minister of Production Piero Ghezzi indicated that ‘With this CFTI we are looking to augment competitiveness, innovative capacity and productive development for participants in this supply chain, in order to generate more value in the transformation of aquatic products.’ 

One relevant objective for CFTI will be the coordination among universities, research centers and NGO’s of research and improved methodologies required by industry, through cooperation within the country and with international partners.

Imports Threaten Public Health and Shrimp Aquaculture in 

Mexico

Mazatlan, Sinaloa Jan. 28, 2015. ‘A threat to aquaculture and public health’ is how the Vice President of CANAINPESCA, Humberto Becerra Batista, described the uncontrolled importation of shrimp from South America. Becerra Batista indicated the urgent need to reinforce vigilance in the country’s borders in order to stop the illegal entry of products that could result in health risks to consumers, cause economic damage to local producers and potentially introduce new diseases such as EMS, which the Mexican shrimp farming industry is currently trying to recover from. 

‘Lots of shrimp shows up without any documentation, arriving in a market where it provokes competition due to a lack of product loyalty,’ he said. He called on restaurants in particular to avoid buying shrimp without proper receipts, or traceability, due to the risk it could cause to diners.

COEPRIES Asked to Corroborate or Retract Accusations 

Regarding Shrimp

Culiacan, Sinaloa  Feb. 27, 2015.  The State Secretary of Agriculture, Livestock and Fisheries of Sinaloa, Juan Guerra Ochoa, requested that COEPRIES either corroborate or retract accusations that shrimp found to be contaminated with E. coli in the state of Baja California Sur originated in Sinaloa.  

Guerra Ochoa indicated that in Sinaloa funds are dedicated to establish a comprehensive strategy to reduce risks from contamination, which is being utilized by aquaculture producers who export shrimp with the highest standards for food safety and who, up until now, have had no incidences of such problems.    

He called for intervention by the State Commission for Sanitary Risks in Sinaloa to come up with detailed information, inasmuch as the ongoing accusations do not indicate any location, producer, date of harvest or packing information which would allow traceability of the supposedly contaminated shrimp, adding that without any corroboration these complaints could be perceived as a type of commercial protectionism against aquaculturists in Sinaloa.

Fish Culturists in Huila on 

Alert Due to Falling River Water 

Levels

In the event of oxygen deficiencies, authorities recommend producers reduce stocking densities.

Neiva, Huila, Colombia. 5 Feb., 2015.  Aquaculture producers were warned by the Ministry of Agriculture and Rural Development and by the National Authority for Aquaculture and Fisheries not to lower their guard in preventing losses, and to apply recommended practices for responding to reduced water flows. These recommendations are especially directed at fish producers in the Betania Reservoir in Huila, based on information released by the Colombian Institute of Hydrology, Meteorology and Environmental Studies.  Due to an extremely intense dry season, water levels are continuing to register at medium- to low elevations in the Magdalena River, especially in the middle stretch of the watershed. In general, reduced water flows can be expected to favor more intense algal blooms, reduced oxygen levels within cages, and localized increases in ammonia, nitrites and nitrates.

Producers are encouraged to reduce stocking densities, conduct partial harvests, and generally reduce standing biomass. Reduced feeding rates are another strategy to mitigate low flow rates and limited oxygen levels. Whenever low oxygen levels become a problem, feeding should be limited to the hours between 9 am and 4 pm. Suggested practices to reduce losses based on oxygen levels include:

D.O. > 4 ppm: feed 100% of the daily ration, depending on the appetite of the fish

D.O. 3-4 ppm: feed 50% of the daily ration, spread out over the course of the day

D.O. 1-2 ppm: feed only in the afternoon, based on the fish’s appetite

D.O. < 1 ppm: do not feed

Producers are also encouraged to have emergency aeration available for critical situations, and to participate in an information network developed to allow data on oxygen levels and other water quality parameters to be shared within the industry.
