Yesterday I interviewed Dr. Paul Jivoff, a professor at Rider University, by telephone to learn more about topics at the intersection of science and business of blue claw crabs. Dr. Jivoff is a local expert in blue claw crabs and we’ve communicated several times over the past few years, including our meeting with the Rider Development Office last year about the possibility of a research site at Money Island.
The big picture goal is to ensure that our business plans are aligned with the available science and, to the extent possible, consider the possibility of future biological impacts on the industry.
This is an annotated abstract from one of Dr. Jivoff’s papers that overviews the life cycle of blue claw crabs:
“Blue crabs are considered estuarine residents with all life history stages, except for the larval stages, occurring in estuarine waters. Adult females release larvae into the water column near the mouths of estuaries (Millikin and Williams, 1980). Larvae are carried offshore where at least 30 days are required to go through seven zoeal stages (Millikin and Williams, 1980; Epifanio, 2007). As a result, blue crab larvae represent one trophic link between estuarine and oceanic food webs. The final plank-tonic stage (megalopa) returns to the estuary, via wind-driven currents and tides (Epifanio, 2007), where they metamorphose to form the first juvenile stage (<5 mm carapace width) and become benthic. These juveniles grow rapidly, molting on average every 3–4 weeks depending on water temperature (Smith and Chang, 2007), making them important prey for a variety of fish and birds, but they are also important predators on other small invertebrates (Lipcius et al., 2007). Therefore, young juveniles (<20 mm carapace width) occupy shallow, structured habitats that also contain food sources including seagrass beds, macroalgae, and oyster reefs (Lipcius et al., 2007). During the 12–18 months required to reach sexual maturity (at 90–100 mm carapace width), habitat use expands based on size and density-dependent factors (Hines, 2007; Lipcius et al., 2007). Smaller juveniles (20–30 mm carapace width) move to alternative nursery habitats including marsh creeks and marsh-fringed mud flats (Lipcius et al., 2007). Larger juveniles (>20 mm carapace width) begin venturing into unstructured habitats and, as they grow, inhabit deeper areas where they continue to be important predators but are prey to fewer organisms (Hines, 2007). Unlike females that exhibit a final molt to reach maturity, adult males grow throughout their lives (reaching sizes of >200 mm carapace width), molting every 30–40 days depending on temperature, and they typically return to more protective habitats during molting, as they are particularly vulnerable to predators. As a result of ontogenetic shifts in habitat as well as movement into lower salinity areas, blue crabs can be found in a wide array of habitats, throughout the estuarine-to-ocean salinity gradient (e.g., 5–35 ppt) (Hines, 2007; Lipcius et al., 2007). Because they represent both predator (contrary to popular belief, they are not scavengers) and prey in these habitats, blue crabs are a critical component of the estuarine food web both within and between estuarine habitats. Blue crabs have been an important food item for humans since the early 1700s and have supported a commercial and recreational fishery since the 1800s (Kennedy et al., 2007). As a result, blue crabs are part of the historic, economic, and social fabric of communities along the Atlantic and Gulf coasts of the United States. Blue crabs are consumed as “hard crabs” (crabs with a hard carapace, typically in the intermolt stage) and as “soft crabs” (crabs with a soft carapace as a result of recent molting) (Kennedy et al., 2007). The predominant fishing techniques vary with the season and with the sex of the harvested crabs. During the warmer seasons (late spring-late fall), blue crabs are typically harvested with a trap or “pot,” and the catch is predominantly males. During the winter, particularly in the mid-Atlantic region, blue crabs are harvested by a dredge, and the catch is predominantly females.” (Jivoff, P.R.. (2016). Blue crabs. Encyclopedia of Earth Sciences Series. 109-110. 10.1007/978-94-017-8801-4_4.)
We discussed industry practices that might support a larger crab population; specifically that we will not support winter dredging of crabs. Also, we opened discussion on the possibility that Money Island might be a good location for future crab research.
New Jersey Community Capital Awards THRIVE Grant to Baysave Corporation for Blue Claw Crab Industry Recovery Project
“This first community financing success brings us 1/6 of the way toward keeping the Money Island working waterfront marina community viable but only about 1% of the way to long term sustainable total community redevelopment. So the plan is to use this grant to build momentum. We have a series of meetings coming up with investors about additional funding. In the end, I suspect that a crowdfunding will also be required to transform our community to thrive in the years ahead”. – Tony Novak
New Brunswick, NJ (October 25, 2018) – New Jersey Community Capital (“NJCC”) announced through its THRIVE South Jersey initiative, it has awarded a $15,000 grant to Baysave Corporation to support the Baysave Crab Industry Recovery Project. This investment will fund capital improvements and technical assistance to enhance the existing infrastructure in Money Island, New Jersey and reestablish the blue claw crab industry for independent commercial crabbers in the community.
As a bay shore community along the coast of New Jersey, Money Island boasts a robust blue claw crab industry. While the town has suffered economically from the effects of Hurricane Sandy and other climate‐related challenges, oyster and blue claw crab fishing remain an in‐demand trade. The $15,000 grant will provide the needed funding to seed the development and operation of an independent crab cooperative.
“New Jersey Community Capital plays a vital role in helping businesses gain invaluable resources to start, grow, and succeed,” says Tony Novak, Executive Director of Baysave Corporation. “This grant further enhances Baysave Corporation’s ability to support small business practices in the blue claw crab industry while growing greater economic resiliency in our community.”
“We believe that providing access to capital is essential for driving economic growth and opportunity for local residents,” says Wayne T. Meyer, President of New Jersey Community Capital. “As mission‐driven lenders, our goal is to help ensure that communities are given the resources and technical assistance to empower and fuel small business success. Through the THRIVE SJ initiative, NJCC will be able to support the projects and activities that supplement job creation and drive long‐term economic impact.”
THRIVE South Jersey works to expand local and regional capacity to generate economic growth in the targeted region of Southern New Jersey that includes Cumberland, Gloucester, Salem, and western Atlantic counties. Through a combination of strategic funding and capacity building, THRIVE South Jersey seeks to support organizations fostering community revitalization activities that generate jobs and sustain low‐income families in the four county region.

My work involves speaking with a wide range of people about observations in nature. I am clear that this is the largest issue affecting our lives, our community’s future and our society but this ‘heavy stuff’ is of course not the message of day-to-day communications. More likely, I get questions like “Why are the fish coming in later?” or “Why can’t I get a building permit?” These are not simple topics to discuss. Like many others in a similar position, I struggle to find the right words to use to communicate the extent of what I observe on a day-to-day basis here at the bayshore. I’ve had more formal training is science in general, and climate science in particular, than most people. Some call it indoctrination. I call it command of facts. But that’s not necessarily an advantage when it comes to leadership. A leader must engage a wide community group base but how is this possible on the issue of climate?
When I think about local media coverage like last June’s front page article in the Philadelphia Inquirer where I was one of several intelligent, educated and well-informed business owners (I know them all pretty well since this is such a small community) who deal with climate issues on a day-to-day basis at the core of their businesses. The writer chose to give more print and apparently did not make any attempt to fact check the statements of the local mayor who said “There is no sea-level rise, and it’s a bunch of hogwash”. The mayor admits that he has no training in science or climate issues. Yet his statement as given more prominence that the considerable better-informed sources. Why would a major newspaper allow this? Would they have printed the story the same if the mayor said the earth is flat or that the planet was created 5,000 years ago? If not, then what possible basis are we using to justify the public expression of these unchallenged false climate statements? This is just one example. I am also aware of a local book writer whose work in progress seems to give credence to climate deniers.
I know that certain words trigger an angry response, can cause our businesses to lose customers and may even cause us to lose government infrastructure funding. I’ve been physically assaulted and verbally threatened for my talk about climate-related issues. Yet I’ve been clear that climate denial is not a logically or legally defensible position. In fact I would be willing to be a witness for the prosecution in future cases that challenge climate change deniers.
In our local market dominated by trumpist thinking, even mention of the term “climate change” in print sets off angry responses. Other words like “strategic retreat”, “inundation”, “sea level rise”, “fact”, and even “science” itself are controversial.
So how then do I talk about the things I see and the things I can’t explain without an understanding of climate issues? It his latest book Thomas Friedman1 offers some suggestions from his conversations with Greenlanders:
“Just a few years ago,… but then something changed…”
“Wow, I’ve never seen that before…”
“Well, usually, but now I don’t know anymore…”
“We haven’t seen something like that since…”
That’s all climate-speak—“surpassing,” “highest,” “record,” “broken,” “biggest,” “longest.”
The fact is that the impact of climate change, acidification, sea level rise and warming temperatures affect me and my industry more than anything else. It would be nice to be able to talk about it.
