Fish Results & Data

Students participating in Mass Audubon’s Salt Marsh Science Project are helping collect data on fish. Many sites that they are investigating are on sites where roads have been blocking the flow of the incoming tide. To investigate whether these “tidal restrictions” are affecting fish, minnow traps are set on both sides: upstream and downstream. Middle School and High School students are investigating sites on the North Shore of Massachusetts. 

Our Questions include:

  • Where is there a greater number of fish?
  • Where is biodiversity greater?
  • Is the size of fish affected by their location: upstream or downstream of a tidal restriction.

Peces

Los estudiantes que participan en Salt Marsh Proyecto de Ciencias de Mass Audubon ayudan a recopilar datos sobre los peces. Muchos sitios que se están investigando son los sitios donde las carreteras han estado bloqueando el flujo de la marea entrante. Para investigar si estas "restricciones de marea" están afectando a los peces, las trampas minnow se establecen en ambos lados: aguas arriba y aguas abajo. Escuela y los estudiantes de secundaria están investigando sitios en la costa norte de Massachusetts.

Nuestras preguntas son:

¿Dónde hay un mayor número de peces?
¿Dónde está la biodiversidad más grande?
¿El tamaño de los peces afectados por su ubicación: aguas arriba o aguas abajo de una restricción de marea.

Data

With the help participating students, we have been collecting data on fish as it relates to salt marshes in coastal Massachusetts since 1996. Please note that not all sites are monitored each year. The date range indicates the start date and the most recent year data was collected.
