Lawn mower

A lawn mower (mower, etc.) is a machine utilizing one or more revolving blades to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. The blades may be powered by muscle, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin, or the machine may have a battery-powered or plug-in electric motor. The most common power source for lawn mowers is a small (typically one cylinder) internal combustion engine, particularly for larger, self-propelled mowers. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" types, or more often, are "ride-on" mowers, equipped so the operator can ride on the mower and control it. A robotic lawn mower ("lawn-mowing bot", "mowbot", etc.) is designed to operate either entirely on its own, or less commonly by an operator by remote control.

Hybrid striped bass

A hybrid striped bass, also known as a wiper or whiterock bass, is a hybrid between the striped bass (Morone saxatilis) and the white bass (M. chrysops). It can be distinguished from the striped bass by broken rather than solid horizontal stripes on the body. Hybrid striped bass are considered better suited for culture in ponds than either parent species because they are more resilient to extremes of temperature and to low dissolved oxygen.

They became part of aquaculture in the United States in the late 1980s. Most producers purchase the fish young (as fry or fingerlings) and raise them in freshwater ponds. Currently, about 10 million lb (4.5 million kg) are produced annually in the United States. Hybrid striped bass are used both as a gamefish and a food fish.

Most of these fish are produced by fertilizing eggs from white bass with sperm from striped bass; the resulting fish are also called "sunshine bass" or "Cherokee bass".

Hybrid striped bass are known for aggressive feeding habits which makes them highly sought-after by anglers. Often schooling by the thousands, these stocked fish surface feed on baitfish such as shad. Often called "breaking", this surface feeding makes the fish visible and easy to catch on a wide array of lures and baits. Popular lures include casting spoons, buck-tail jigs, soft-body plastic fish replicas, and inline spinners.
