Variaciones en la composición bioquímica proximal de la anchoíta durante tres temporadas de pesca (1975-1977)
MetadataShow full item record
Seasonal variations in major biochemical compoenets (lipids, protein and water)as well as in ash content of muscle and filletin remains of Engraulis anchoita were studied separately along three consecutive fishing seasons (May-December 1975, 1976 and 1977). Five to ten adult fish of each sex and of nearly identical length (total length: 160-165 mm)were selected at approximately monthly intervals from commercial catches at Mar del Plata Harbour. During the course of the three sampling periods, the proportions of the different biochemcial components showed a very similar pattern of variation and the difference from one fishing season to another never exceeded one month.
