Clams removal

The best recipes for clam chowder all include onions and a bay leaf. The onions add a sharpness and zest to the blandness of the clams, and also help remove their slimy texture. The bay leaf complements the onion s strong flavor. 

In addition to these passive processes shellfish have been shown to actively modify the saxitoxins. Shimizu has shown (40) that scallops can remove both the N-l-hydroxyl and 11-hydroxysulfate groups from the saxitoxins. Sullivan has shown ( ) that enzymes in littleneck clams can remove the sulfamate or carbamate side chain, yielding the decarbamoyl toxins. This activity was not detected in either mussels or butter clams. With both sorts of modification the products are compounds that have higher potency and are likely to be bound in shellfish more strongly. 

Despite this progress, the evidence linking cysts to shellfish toxicity remains circumstantial and care should be exercised before attributing toxin increases to this mechanism. The major problem is that it has yet to be demonstrated that shellfish can remove toxin from cysts. The feeding studies mentioned earlier (which do not yet include scallops 35) indicate that many viable G. tamarensis cysts can be isolated from the fecal pellets of mussels and soft-shelled clams fed cyst suspensions. There is certainly some cyst mortality as well (Figure 5), but whether this is also associated with toxin retention by the shellfish has yet to be demonstrated. It is reasonable to expect that the assimilation of toxin from cysts will not be a highly efficient process. 

Shellfish. Before opening, wash exterior of the shell with a brush and potable water to remove all loose silt and dirt, and drain. Separate the edible portion from shells of at least 10 specimens, place in a suitable tared container and determine the wet weight. Blend the sample (solid and liquid) using a blender with stainless steel blades and Teflon gaskets. After removing edible portions from shell oysters, shell clams and scallops, transfer the shellfish meats to a skimmer, pick out pieces of shell and drain for 2 min before homogenizing meat and liquid.

Design of the roller surfaces In designing a roller press surface, some fundamental considerations do influence the possible shape, size, and distribution of the cups or indentations.Limitations include the relationships of circumferential pocket dimension/roller circumference and pocket depth/roller diameter as well as the pocket shape. Associated with these are problems of release, clam-shelling (splitting), extrusion, removal of air from the compaction zone, and uneven distribution of feed as well as compaction pressure. In spite of those limitations, a large variety of shapes can be produced. 

With rotational molding, a closed mold is rotated in two or more planes during fusion or solidification of the fluid polymer system. The action of the rotation deposits an even coating of polymer upon the inside of a "clam shell" type mold. After a predetermined time under heat, the molds are removed from the oven and cooled, and the finished product is removed whereupon the cycle is started again. Conventional gas fired ovens or hot salt bath sprays are used for heat transfer, and cooling is usually effected by spraying or immersion in cold water. This technique is well suited to molding completely hollow objects. 

Harvesting of other molluscan shellfish for canning purposes is permitfed in areas where scores are between 80 pg/100 g and 160 pg/100 g and the canned packs are tested before release for sale. On the Pacihc Coast, butter clam canning has been permitted up to 300-500 pg/100 g, where it is done under permit and the neck has been removed and discarded [7].

Uses.—Spread on leather for the removal of bony tumours. One part of this ointment, mixed with two parts of lard, is used for dressing Professor Yamell s caustic clams. 

No one can estimate how many fish, crabs, oysters, and clams have succumbed to the poisons dumped in the Chesapeake Bay. As these containers breach, sea life in the vicinity will be certainly killed. Efforts should be made to locate these munitions and remove them or encapsulate them in concrete. 

Shortly after fertilization, the sperm nuclear envelope is rapidly broken down inside the egg cytoplasm. In vivo, removal of the sperm nuclear envelope has been documented by electron microscopy in both the sea urchin (Longo and Anderson, 1968 Longo, 1976) and the surf clam (Longo and Anderson, 1970). These studies have shown that breakdown of these envelopes is incomplete. A small portion of the nuclear envelope associated with other material appears to... 

Surf Clam. Testes are removed from ripe males and held on ice. Sperm are released by mincing and collected dry. To our knowledge, storage of intact sperm has not been reported. 

A cytosolic extract essentially free of MVs can be prepared from the S o extract (Collas and Poccia, 1995a). Cytosolic extracts support sperm chromatin decondensation, histone phosphorylation (Green et ai, 1995), and sperm lamin removal, but not nuclear envelope assembly (Collas et ai, 1995). To our knowledge, no such extracts have been investigated for the surf clam.
