Piracema é o nome dado ao período de desova dos peixes , que compreende toda a região do Pantanal nos estados de Mato Grosso e Mato Grosso do Sul.
 
O período da piracema ocorre entre outubro e março, quando os peixes nadam contra a corrente para realizar a desova, de modo a poderem reproduzir-se. Tal evento é fundamental para a preservação da piscosidade (abundância de peixes) nas águas de rios e lagoas. Neste período é proibida a pesca nos dois estados.
