Biscay at the end of spring, by applying the daily egg production method (MPHD), undertaking various studies and sampling throughout the anchovy reproduction area.<\/p>\n\n\n\n<p>After collecting plankton samples, the eggs spawned by the anchovies are extracted. At the same time, samples of adult anchovies are collected to later calculate their average fertility; that is, the average number of eggs produced by each female. The relationship between the quantity of eggs found in the plankton and the average fertility of the females allows AZTI experts to estimate the biomass of this marine resource, considered to be one of the pillars of the economy of the Basque fishing sector and of the entire Cantabrian coast.<\/p>\n\n\n\n<p>The Bioman study in spring is complemented by the <strong>Juvena<\/strong> campaign in autumn, in which AZTI&#8217;s research personnel determine the abundance and spatial distribution of young anchovies, study their condition and analyse the environmental factors that affect their survival. In this way, the technicians can predict the amount of anchovy that will enter the adult population the following year and that will sustain the fishery.<\/p>\n\n\n\n<p>The importance of the campaign lies in the fact that only through sustainable management is it possible to guarantee the survival of the species and the future of the economic activity generated by this fishery both in the fishing sector and in the canning and food industry, which employs more than 3,500 people.<\/p>\n\n\n\n<h2>Useful Documentation<\/h2>\n\n\n\n<p><a
