The Chilean producer has reduced its Atlantic salmon production costs ex-cage by over US$ 0.50 per kg in the past two years thanks to improved biological results. Yield of produced kg WFE per smolt and accumulated mortality rate are among the most enhanced indexes.

Salmones Multiexport recorded a 12 per cent decrease in its production cost ex-cage in the first nine months of this year compared to the same period of 2014. That means the company has reduced its ex-cage costs from almost US$ 4.4/kg WFE to an expected US$ 3.8/kg by the end of this year.

According to the company, this is the consequence of an improved biological performance due to, for example, higher yield of produced kg WFE per smolt, lower accumulated mortality rate, as well as larger average harvest weights and growth rates.

While in 2013 the Chilean salmon industry averaged a yield of 3.51 kg WFE produced per smolt of Atlantic salmon, year-to-date (YTD) the local industry averages 4.26 kg WFE produced per smolt and Multiexport records 4.91 kg WFE over the same last period.

Likewise, while the local industry registered an accumulated mortality rate close to 19 per cent in 2013, the Chilean companies have managed to reduce that figure to an average of 14 per cent YTD, and Multiexport has gone even further reducing it to an accumulated mortality rate below 9 per cent, said the company.

Similar improvements are seen in the average harvest weight, which is close to 5.3 kg in Multiexport, and the growth rate, which is of 325 g WFE per month for harvested fish in the same company.
