A little cold in the AM. Once the sun got going, it warmed up nicely. Fun 10.5 meter pond sess with Mike. (great jumps Mike!). Ponds started to die off around 1ish. Headed down to the volleyball courts. Usual crowd out rippen.

Ps Hippies need love too!

Yeah pretty crazy to see how much sand has been stripped away. Tons and tons. I guess the high water will bring new sand for next year. Also, whats up with all the clams showing up ( not that kind.... Laughing

) they are taking over the beachs. I hear they are non native. They are going to be a big problem. They are sharp and prolific.

Ps Way to score the "liquid lunch" Tom Thumb's Up

Fuck yeah. There's something in the water... Wink

Killer yesterday. Migraine, fever, puking... today's better though!

Man, sorry to hear that Adam.

Great day! Thanks for the props on the jumps Mark; Adam and Amery will have some competition now! Very Happy

(NOT) Really weird though, the wind died off at the ponds before it died at the West end of RR. I've never seen that before...

Clam talk....

Because each clam is capable of breeding up to 400 clams per day when the water is warm, the population could quickly swell into the thousands this summer, he said.

Corbicula fluminea
Common Name: Asian clam

Synonyms and Other Names: Asiatic clam

Taxonomy: available through

Identification: A small light-colored bivalve with shell ornamented by distinct, concentric sulcations, anterior and posterior lateral teeth with many fine serations. Dark shell morphs exist but are limited to the southwestern United States. The light-colored shell morph has a yellow-green to light brown periostracum and white to light blue or light purple nacre while the darker shell morph has a dark olive green to black periostracum and a deep royal blue nacre (McMahon 1991).

Size: < 50 mm

Native Range: The genus Corbicula lives in temperate to tropical southern Asia west to the eastern Mediterranean; Africa, except in the Sahara desert; southeast Asian islands south into central and eastern Australia (Morton 1986).

Ecology: Asian clams are filter feeders that remove particles from the water column. They can be found at the sediment suface or slightly buried. The ability to reproduce rapidly coupled with low tolerance of cold temperatures can produce wild swings in populaton sizes from year to year in northern water bodies.

Means of Introduction:

The first collection of C. fluminea in the United States occurred in 1938 along the banks of the Columbia River near Knappton, Washington (Counts 1986). Since this first introduction, it is now found in 38 states and the District of Columbia. Corbicula fluminea was thought to enter the United States as a food item used by Chinese immigrants. Or, it may have come in with the importation of the Giant Pacific oyster also from the Asia. The mechanism for dispersal within North America is unknown. It is known mostly as a biofouler of many electrical and nuclear power plants across the country. As water is drawn from rivers, streams and reservoirs for cooling purposes so are Corbicula larvae. Once inside the plant, this mussel can clog condenser tubes, raw service water pipes, and fire fighting equipment. Economic problems can result from the decreased efficiency of energy generation. Warm water effluents at these power plants make a hospitable environment for stabilizing populations. With man shown to be the primary agent of dispersal, no large-scale geographic features function as dispersal barriers (Counts 1986; Isom 1986). Current methods of introduction include bait bucket introductions (Counts 1986), accidental introductions associated with imported aquaculture species (Counts 1986), and intentional introductions by people who buy them as a food item in markets (Devick 1991). The only other significant dispersal agent is thought to be passive movement via water currents (Isom 1986); fish and birds are not considered to be significant distribution vectors (Counts 1986; Isom 1986).

Status: Corbicula fluminea has become established in all states listed above.

Impact of Introduction: The most prominent effect of the introduction of the Asian clam into the United States has been biofouling, especially of complex power plant and industrial water systems (Isom et al. 1986; Williams and McMahon 1986). It has also be documented to cause problems in irrigation canals and pipes (Prokopovich and Hebert 1965; Devick 1991) and drinking water supplies (Smith et al. 1979). It also alters benthic substrates (Sickel 1986), and competes with native species for limited resources (Devick 1991).

Remarks: Factors that may affect population density and distribution of Asian clams include excessively high or low temperatures, salinity, drying, low pH, silt, hypoxia, pollution, bacterial, viral and parasitic infections, inter- and intraspecific competition, predators, and genetic changes (Evans et al. 1979; Sickel 1986). These clams have been found in the stomachs of black buffalo - Ictiobus niger (Minckley 1973); carp - Cyprinus carpio, channel catfish - Ictalurus punctatus, yellow bullhead - Ameiurus natalis, redear sunfish - Lepomis microlophus, largemouth bass - Micropterus salmoides, Mozambique tilapia - Tilapia mossambica (Minckley 1982); blue catfish - Ictalurus furcatus (M. Moser pers. comm. 1996); and spotted catfish - Ameiurus serracanthus (A. Foster pers. comm. 1996). Other predators of Corbicula include birds, raccoons, crayfish, and flatworms (Sickel 1986). Densities of C. fluminea have also been documented to occur by the thousands per square meter, often dominating the benthic community (Sickel 1986).

Clamtastic!

Some fatties out there - looked good eatin if you where on survivor island or lookin to grow a thrid nipple.

Rooster finally mellowed out - hopefully not for the season was a good run
