    Shrimp Production Results in Experimental Ponds in Ecuador with Presence of WSSV: Three Lucky Strikes or Three Indications of Hope for the Shrimp Industry? by Velasco, Mario, Freire, Gorki, Arias, Arturo, Quiroz, Miguel

    Published 2019
    “…Since the very first appearance of White Spot Syndrome Virus (WSSV) in April 1999 inCentral and South America, massive mortalities of Pacific white shrimp, Litopenaeusvannamei (Boone), in semi-intensive ponds are occurring. In very few cases shrimpsurvival is above 25 %. Three experiments were conducted in Ecuador from March 2000 toMay 2001 to compare production results of shrimp directly stocked in 100 m2 ponds at150000 PL-12 / Ha. …”

    La consulta popular en México: un replanteamiento para superarlainoperabilidad a la luz de los primeros resultados y los modelos Latinoamericanos. by López Sáenz, Emanuel
