Hello Club Members & Friends,
Our April dive day at Fisherman’s was cancelled do to high surf forecast. I decided to cancel, because my
surfline subscriber forecast was 3-4’ surf & building. I figured better safe then sorry. The Cee ray is sold out for Cham-
ber day, but John Baker’s spot may be available contact him if you’re Interested.
A group of club members are going to the scuba show on May 5th. Talk to John Baker or Robert Openshaw to join
the group. I will not be going, I have a prior commitment.
The drift dive trip to Laughlin will be on May 20th & 21st. I’lI be going up early on the 19th to get set up &
settled. I found the best rate at the Colorado Belle, but check Hot wire. The plan is to do a drift dive early Sat morn-
ing, then head to the lake for some diving at cabin site cove & possibly Wreck Alley , and one final drift dive Sunday
morning which will also satisfy the drift dive specialty for those of you who would like to do the specialty.
As always let me know if any of you have suggestions for speakers, or Ideas for outings.
Good Diving
Mike Tommaney

rahs start heading toward the

is a drop, a bend, the current
slows. Swim into the cove &

Creature of the month
Quagga Mussel
The quagga mussel, scientific name Dreissena bugensis, and also known as Dreissena rostriformis bugensis, is a species (or subspe-cies) of freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.
This freshwater mussel has an average life span of 3 to 5 years.[2]
This subspecies is indigenous to the Dnieper River drainage of Ukraine. The species is named after the quagga, an extinct subspe-cies of African zebra, possibly because, like the quagga, its stripes fade out towards the ventral side.
The quagga mussel is currently of major concern in the Great Lakes of North America as an invasive species brought by overseas shippers that use the St. Lawrence Seaway.
The quagga mussel shell is striped and/or zig-zagged, as is that of the zebra mussel, but the quagga shell is paler toward the end of the hinge. There is a large range of shell morphologies, including a distinct morph in Lake Erie that is pale or completely white. The quagga is slightly larger than the zebra mussel, about 20 millimetres (0.8 in) wide, roughly about the size of an adult human's thumbnail. The quagga has a rounded carina and a convex ventral side.
The quagga mussel is a filter feeder. It uses its cilia to pull water into its shell cavity through an incurrent siphon and it is here that desirable particulate matter is removed. Each adult mussel is capable of filtering one or more liters of water each day, where they remove phytoplankton, zooplankton, algae, and even their own veligers. Any undesirable particulate matter is bound with mucus, known as pseudofeces, and ejected out the incurrent siphon. The particle-free water is then discharged out the excurrent siphon.
The quagga mussel is a prolific breeder, possibly contributing to its spread and abundance. Dreissena are dioecious (either male or female) with external fertilization. A fully mature female mussel is capable of producing up to one million eggs per year. After fer-tilization, pelagic microscopic larvae, or veligers, develop within a few days and these veligers soon acquire minute bivalve shells. Free-swimming veligers drift with the currents for three to four weeks feeding by their hair-like cilia while trying to locate suitable substrata to settle and secure byssal threads. Mortality in this transitional stage from planktonic veliger to settled juveniles may exceed 99%.[3]
