The tabby patterns are due to three distinct gene loci and one modifier: The agouti gene, "A/a", controls whether or not the tabby pattern is expressed. The dominant "A" expresses the underlying tabby pattern, while the recessive non-agouti
Mackerel as food in these fish and the consequent risk of mercury poisoning. Mackerel as food Mackerel is an important food fish that is consumed worldwide. As an oily fish, it is a rich source of omega-3 fatty acids. The flesh of mackerel spoils quickly, especially in the tropics, and can cause scombroid food poisoning. Accordingly, it should be eaten on the day of capture, unless properly refrigerated or cured. Mackerel preservation is not simple. Before the 19th-century development of canning and the widespread availability of refrigeration, salting and smoking were the principal preservation methods available.
