Honduras

SeaJoy/Deli Group

 

At the Tenth Central American Aquaculture Symposium (Tegucigalpa, Honduras, August 27-29, 2014), attendees received a 66-page, slick-paper magazine that included brief articles in English and Spanish that summarized all the presentations.  Here’s the summary of Mario Alvarez’s (SeaJoy/Deli Group) presentation from that magazine.

 

DELI GROUP’s farms are located in Honduras and Nicaragua on the Gulf of Fonseca.  In Nicaragua, it has 690 hectares of ponds, and in Honduras, 1,736 hectares.   In addition, it has 91 hectares of nursery ponds.  In the last several years, its production has been steadily improving, and in 2014 it expects to produce 17 million pounds of whole shrimp.

 

Its farms are semi-intensive with stocking densities ranging from 7-15 shrimp per square meter.  For the first crop of the year, postlarvae (PLs) are stocked directly into the growout ponds, but for the second, third and fourth crops, the ponds are stocked from nurseries.  The first crop is stocked in January and February, the second crop in April and July, and the third and fourth crops are stocked between July and the beginning of October.  The rainy season begins in September, and October is the wettest month of the year.  Cold fronts can occur late in November, dropping water temperatures below 25 degrees and increasing the possibility of diseases, so the last two crops of the year are stocked at lower densities (5-7 shrimp m2) to reduce the risk of economic loss.  After the last harvest of the year, the ponds lie fallow until temperatures begin to warm up again in late January.

 

Natural productivity of the ponds is encouraged and production during the first two crops ranges between 2,500 to 3,000 pounds per hectare.  During crops three and four, production ranges between 1,200 to 2,000 pounds per hectare.

 

Feeding is done two to three times a day when temperatures range between 28-32 degrees Celsius and oxygen levels are above three parts per million.  When conditions are perfect and the shrimp are growing rapidly, feeds are delivered four times a day.  Nitrogen and silicate fertilization, which costs from $150 to $300 per hectare per crop, is done to balance nitrogen and potassium ratios.
