Sonora first harvests yield 865 tonnes of shrimp
In the first farmed shrimp harvests in Sonora 865 tonnes were obtained, without having registered significant sanitary issues as those from previous years.
This was announced by the manager of Aquaculture Health Committee of the State of Sonora (COSAES), Baltazar Chavez Dominguez, who said that 29 farms managed to obtain yields of 300 kilograms per hectare and the average mortality rate in this cycle is 10 per cent.
Chavez Dominguez said they had received 89 reports on mortality events on farms. Out of the total, three were presented at the nursing stage, with mortality rates of 90 to 100 per cent, and were attributed to management problems. The analyzes performed did not reveal any evidence of any pathological issues, he stressed, according to Notimex.
In the fattening phase 86 mortality events were reported in organisms with sizes from 0.03 to 12 grams. These were those cases focused only on some ponds, which together represent about 25 per cent of the set surface.
COSAES officers said that in Sonora 183 production units are operating, of which 33 are authorized to operate in intensive system.
So far, there are 138 units that are operating, of which 46 have nursing facilities.
In 2013, farmed shrimp production in Sonora fell by 70 per cent due to the negative impact of the white spot disease virus and of the early mortality syndrome, which caused mortalities of up to 80 per cent in the first 50 days of the farming season.
