Introduction to Green Crab

Introduction to Green Crab

Why should we care about these tiny green crabs? As you read the introduction below, you will understand. This was taken directly from the "Green Crab Working Summit 2018" in Portland, Maine, written by scientist/researcher Dr. Gabriela Bradt, an expert on green crab. She gave permission to reprint this introduction in my blog.   

I encourage you to eat more green crab!

Green Crab Working Summit 2018

The East Coast wave of the green crab invasion occurred 200 years ago and they have since firmly established themselves from New England to Prince Edward Island, Canada, wrecking ecological and economic havoc along the way. We are not the first to research and propose solutions to reign in these nuisance crustaceans, in fact some of the ideas and work being presented and discussed over the next several days have been proposed or attempted in the past. However, in the years since people have been investigating this problem, not one, long-term, lucrative, eco-beneficial and viable mitigation/control plan has actually been truly successful at achieving this. There are many reasons for this, including lack of funding, processing capabilities, technology, and perseverance. Green crabs are successful invaders because they possess many biological and physiological properties that allow them to exploit diverse habitats, withstand broad ranges of temperature and salinity, as well as the ability to survive out of water and without eating for extensive periods. Along with few natural predators and high fecundity, green crabs are very likely the 'model' invasive species that have gone unchecked for too long.

However, the time to finally get a handle on this invasive crustacean appears to have arrived. The combination of warming ocean temperatures, increasing regulations on wild harvest fisheries, fish populations at historically low levels, as well as continued demand for fresh, local seafood and continued devastation of shellfish fisheries and estuarine and coastal habitats by these crustaceans, has lead to the perfect confluence of factors driving the need for population control while also developing diverse uses and markets for this nutritious and abundant crab that happens to be an invasive species. Controlling green crabs populations has the potential to positively impact shellfish fisheries through reduced predation, create new economic opportunity for fishermen, bring a new, local and abundant seafood product to the region, AND restore biodiversity and critical estuarine, marsh and coastal ecosystems. The possible uses and products from green crabs that have high market potential are many, and their development and manufacture are critical. The time to develop and investigate in these products is now, and it is why we decided to put together this summit. We want to bring all stakeholders to the table and see what we can learn from each other that will be helpful, feasible and ultimately successful in mitigating this nuisance species.

Let's use our broad and vast experience to explore, develop and expand markets, biocontrol methods and the potential of a green crab "Fishery".

LET'S DO THIS!

Green Crab Ice Cream

The best part about making my own ice cream is that I can control the amount of sugar that goes in it and I can add just about anything that...
