El trabajo observado para la colecta de organismos y sedimentos nos muestra otras técnicas de pesca así como la toma de las muestras. Donde se puede obtimizar el volumen de muestra para diversos análisis por organismo. The work observed collecting…
En la colaboración del Dr. Steve de la Universidad del Sur de Florida y del Dr. Adolfo Gracia de la Universidad Nacional Autónoma de México pude observar diferencias en la forma de trabajo; debido a que el arte de pesca…
