Determinar la importancia del manejo de la red de plancton en la recolección de muestras

Abstract

Phytoplankton generates half of the oxygen that circulates around the planet, also, this marine organism helps to retain two billion tons of carbon dioxide per year, it also serves as food for many species and it is constantly threatened by climate change. These samples are collected by means of the plankton net, but in the market there are several types of nets that have different uses where it is at the discretion of the researcher its use or convenience, one of the nets has a simpler handling making it easier to use, this is known as the conical or simple plankton net. There are two methods based on the scope of the study or study to be carried out; it should be noted that once the samples have been collected using these devices, they allow us to determine the presence or absence of certain plantonic species known to be linked to eutrophicated areas, as well as the production of Cylindrospermopsin and Saxitosin, which can have a negative impact on other organisms present in these ecosystems and therefore on human health, by means of a quantitative and qualitative analysis. After obtaining the samples we must know which is the most efficient form of preservation, since one of the compounds to preserve tends to expand the body of the organisms to be studied and another one is dangerous in its manipulation, it is also necessary to know the percentage of concentration that should be used to avoid risks during the manipulation process.
