Sample Watch Presentation Issues for Warner,
- Speech of watermen as W's motive for writing--wisdom of
the community vs. wisdom of isolated expert scientists (xvi-xvii).
- Size of the Bay: 200 miles long x 30 miles wide (at the
widest, below Annapolis); 4,000 miles of shoreline--the largest estuary in
the United States (3-5)
- Water structure: "salinity gradation" as crucial to
species reproduction, feeding, survival: salt heavier than fresh, flows
below the outflowing rivers: Susquehanna, Potomac, Patapsco, Chester,
Pawtuxent, Choptank, Severn, Charles, etc. Crabs navigate the entire
length of the Bay twice a year (53).
- Crabs' instincts (19-20) as part of how watermen catch
them with traps (seeking to escape by swimming or climbing up); sight
hunters (but with very good sense of smell--see Horton on crab
mating--recent science on pheromones); shun pots that contain only one dead
- Fall migration: females south to the mud bottom at Bay
mouth (dredging from VA side); males to deep holes in channel and off
- "Right of Free Plunder": watermen's belief in natural law
over state or federal law (77 and 89).
- Crab survival rates: 1 in a million eggs produces an
adult crab / 2 million eggs per female = 2 crabs per surviving female per
- Crab life span = 3 years (109)
- "Sea run crabs": return after cycling through ocean
gyres, covered in barnacles, etc.--live longer than 3 years? (110-119).
