Tabby cat basic color pattern. The "Patched" tabby is a calico or tortoiseshell cat with tabby patches (also known as "caliby" and "torbie", respectively). All those patterns have been observed in random-bred populations. Several additional patterns are found in specific breeds. A modified Classic tabby is found in the Sokoke breed. Some are due to the interaction of wild and domestic genes. Rosetted and marbled patterns are found in the Bengal breed. The Mackerel tabby pattern has vertical, gently curving stripes on the side of the body. The stripes are narrow and may be continuous or broken into bars and spots on
Mackerel for about 75% of the total catch of scombroid mackerels. Chilean jack mackerel are the most commonly fished non-scombroid mackerel, fished as heavily as chub mackerel (see second graph on the right). The species has been overfished, and its fishery may now be in danger of collapsing. Smaller mackerel behave like herrings, and are captured in similar ways. Fish species like these, which school near the surface, can be caught efficiently by purse seining. Huge purse seiner vessels use spotter planes to locate the schooling fish. Then they close in using sophisticated sonar to track the shape of the shoal.
