The early life and struggles of alewives in a New Jersey river system
Alewives (Alosa pseudoharengus; Figure 1) are small, silvery forage fish found along the East Coast from Newfoundland to the Carolinas. They are commonly referred to as river herring along with […]
Spawning sea lampreys influence macroinvertebrate communities in streams
Sea lampreys (Petromyzon marinus) are a jawless species of fish native to the northern Atlantic Ocean and Mediterranean Sea. They have a complex life cycle that begins and ends in […]
Temperature, not tides, influence horseshoe crab spawning activity in New Hampshire’s Great Bay
The Atlantic horseshoe crab (Limulus polyphemus) is a marine invertebrate whose native range spans from the Gulf of Maine to the Gulf of Mexico. This species is ecologically and economically […]
Angling for nesting largemouth bass can have negative effects on spawning success
Largemouth bass (Micropterus salmoides; Figure 1) are a highly prized freshwater gamefish in the sunfish family, Centrarchidae. They are native to east-central North America but have been introduced worldwide due […]
Alewife spawning strategies may differ between river systems
Alewives (Alosa pseudoharengus) are small, silvery forage fish in the family Clupeidae (Figure 1). Their native range spans the eastern seaboard of North America from South Carolina to Newfoundland. Historically, […]
Importance of a marine conservation zone for blue crabs
Marine Protected Areas (MPAs) are areas where human activities are restricted for conservation or historical purposes. These restrictions can include limitations on fishing, development, and anything that disrupts aquatic life. […]
Physical properties of estuaries influence blue crab populations
Blue crabs (Callinectes sapidus) are a species of crab native to estuaries along the western Atlantic coast from Nova Scotia to northern Argentina (Figure 1). They live on soft-bottom habitats […]
Where to spawn? Muskellunge prefer spawning at the same site annually
If you have never seen a muskellunge (Esox masquinongy), they are magnificent, large, and powerful apex predators in the waterbodies they reside (Figure 1). Georgian Bay in Lake Huron supports […]
Effects of dam removals on riverine fish assemblages
In many rivers throughout the world, dams have greatly altered the aquatic ecosystem. These structures block migratory routes for anadromous species that live in saltwater and migrate into freshwater to […]
Using oyster toadfish calls to monitor restored oyster reefs
Oyster reefs are dense colonies made up of thousands of individual oysters attached to hard substrate (Figure 1). Because of their complex structures, oyster reefs provide important habitat for a […]
Horseshoe crab spawning activity after beach nourishment
Horseshoe crabs (Limulus polyphemus) are a species of marine arthropod native to the Atlantic coast of North America, ranging from the Gulf of Maine to the Yucatán Peninsula in Mexico […]
Winter flounder spawning offshore in the southern Gulf of Maine
Winter flounder (Pseudopleuronectes americanus) are small-mouthed flatfish native to the east coast of North America, ranging from Labrador to Georgia. They are right-eyed flounder, meaning that as adults, both eyes […]
Using imaging sonar to count migrating river herring
Alewives (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), collectively known as river herring, are small, silvery fish native to the east coast of North America. They are anadromous, meaning they […]
Using side-scan sonar to map Walleye spawning habitat
The sustainability of fish populations relies on the ability of adult fish to at least replace themselves. To do so, they must spawn successfully, and this requires suitable spawning habitat. […]
