Ok here is the thing. I do not like most sea foods (not even tuna fish), except for the ones that are not kosher namely shrimp and clam. The thing is this-
"Seafood is an excellent source of minerals. Fish are one of the most important sources of calcium. The soft bones of small fish such as sardines and smelts and canned varieties such as salmon are especially valuable sources of calcium. Other minerals in seafood include zinc (oysters and crustaceans), iron (oysters, bluefish, and shrimp), copper (oysters, crabs, and lobster), potassium (mussels, scallops, and clams), and iodine, phosphorus, and selenium (all seafood in general). Fresh seafood is low in sodium. For those who have to restrict the intake of sodium, fresh seafood is an excellent choice, although you should limit your intake of processed seafoods such as smoked, cured, and most canned seafoods. Salt is added in the processing of these seafood products as it is in imitation seafood products. " from http://www.ocean.udel.edu/mas/seafood/nutritioninfo.html.
So basically due to the fact that I can't stand sea most foods (I love gefilta fish but one can't keep having the same thing every day) and sea food is very important for nutrition, and one would think that nutrition trumps kashrut, I hereby give myself heter leechol bi-shrimp vi-tzedpah. XD
