Although Grass Carp are often used to control selected aquatic weeds, these fish sometimes feed on preferred rather than on target plant species (Taylor et al. The outstanding freshwater fisheries in Texas are often supported by moderate levels of aquatic vegetation. Since grass carp cannot reproduce in ponds and lakes, they are an excellent biological control agent.

Maximum feed intake of grass carp as a function of temperature and body weight is described by Cmax=4.9W-0.24 [(37.5-T)/(37.5-34)]0.68 e [0.68(T-34)/(37.5-34)], where Cmax = maximum feed intake in g feed/g fish/day), T = temperature in °C and W = body weight in g (Wen et al., 1995), while maximum ration as a function of temperature is described by RLmax = 0.04T2.32, where RLmax, % body weight /d and T= temperature in °C (Cui et al. Larvae first feed on protozoa and small zooplankton including rotifers and then switch to larger zooplankton including cladocerans (Dabrowski and Poczyczynski, 1988) and copepods. Grass carp are selective feeders, preferring soft tissue aquatic plant species. Feeding behaviour Feeding behaviour is temperature dependent (Cai and Curtis, 1990) (see Table 2). Today, grass carp are stocked in many private lakes and ponds to control excess vegetation. Grass carp are rapid growers, with fish stocked at eight inches in the spring reaching 18 inches by fall. The fish are primarily herbivorous. At this stage the fish switch to a macrophytic diet. The grass carp is primarily a plant-eating fish native to the Amur River in Asia and is a relatively inexpensive and effective biological tool to control some species of nuisance aquatic vegetation.

Invasive Weeds. Grass carp generally only consume submerged vegetation that has soft/tender, non-fibrous stems and leaves. Because they eat such large quantities of aquatic vegetation, they can affect other native fish communities, primarily through habitat modification, along with waterfowl using lowlands and wetlands.

If populations are sufficiently high, grass carp tend to stimulate phytoplankton blooms that reduce water clarity. Feeding intensity and feed intake is also affected by diet type. When fed on macrophytes or duckweed grass carp feed for almost 24 hours a day, while only a quarter of the diel cycle is devoted to feeding when fed with pellets or animal based diets (Cui et al., 1995). On the other hand Ni and Wang (1999) found that when grass carp feed on macrophytes they do so continuously for 2-3 h with a break of less than one hour between feeding sessions (Table 3).
