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 important. Several species of...
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 to their popularity with...
Oyster aquaculture provides habitat for fish and invertebrates
Eastern oysters (Crassostrea virginica) have traditionally been farmed on leased shellfish beds in estuaries. The most common oyster farming technique in Connecticut waters is called bottom culture. In bottom culture, an oyster bed is...
Expectations of Walleye vertical movement are not always reality
Fish use habitat depending on their needs. Typically, management of fishes relies on what habitats the fish are thought to inhabit. For example, sampling at a single depth can be biased if the fish...
Bass dispersal after weigh-ins at fishing tournaments
Largemouth bass (Micropterus salmoides; Figure 1) and smallmouth bass (Micropterus dolomieu; Figure 2) are two of the most popular species of freshwater fish in North America. Both species are voracious predators and are highly...
Context is important for fish habitat selection
Fish use different habitats based on habitat characteristics, such as vegetation type or bottom composition. Ecologists have long believed that these habitat characteristics determine the makeup of a fish community. Therefore, our idea of...
