the 2 creeks we played in are very urban streams. im still pleased how much
life is in these downtown streams. tho to go back in time im sure would
present enormous diversity. every year pours more and more trash and silt
into these urban waters so the concern for the future is great. as you saw th
e fella had cleared his lawn right to the streams edge. humanity presents all
kinds of actions that can be detrimental.

i think the darter size varies from location size to location. some areas
only yield small redlines yet others can produce some massive ones. i think
it is size and health of habitat that produces the according sizing.

most darters are figured to live 2 or 3 years but some folks claim to have
kept certain species alive for 6, 7 or even 8 years. tho it is impossible to
reproduce mother nature in an aquaria we can provide a predator free and temp
stable environment and if coupled w/ healthy live and frozen foods diet well
that should be benefitial to a longer life.
these little creeks near my home are a great place to take someone if time is
limited. i have been able to snorkle them during rare clear visibility... and
may do it this weekend if the sun shines. the weather and spring is getting
stunning. dogwoods and redbuds are in full bloom and azeleas are fixing to
those little darters were full tilt. i especially liked the speckled darters.
electric metallic blue. unreal.
sorry about the bruises terri... i would have to point to peter unmacks
seining techniques and traching. he is a ruthless man w/ a net. :)
if the pics turn out jay delong may be able to do a mini post on the tn site.
