The second part covers the management of aquatic weeds, with chapters on various control methods. Profuse growths of aquatic plants can also interfere with angling and other water- based recreation and weed masses when detached from their substrate can block streams, pipes and jets.
Some of the problems caused by growths of aquatic weeds and methods available for their control are described by Mitchell (). Among various obnoxious weeds, Parthenium hysterophorus, Cuscuta spp., Orobanche spp., Striga spp.
and Eichhornia crassipes caused severe losses in crop yield. These weeds spreaded so fast that within a few years these have covered substantial areas in the state putting pressure on the natural resources.

For the purpose of description and management, aquatic weeds may be grouped either on the basis of their botanical relationships or on the basis of their growth habits. Most plants in each group are managed similarly, with some exceptions.
Table A. Aquatic Weed Groups — Grouping of Aquatic Plants on the Basis of Botanical Relationships. The background of and the means for biological control of aquatic weeds which are of practical significance in the tropics are discussed.
There are only a few biological agents available which are expected to be of real importance in the near future, i.e. phytophagous fishes, such as grass carp, and arthropods which feed specifically on water hyacinth.
The book deals with fundamental biology, weed growth and management, and the identification, characteristics and control of those weeds which cause most problems. Useful appendices complete a book which will repay its cost many times for owners and managers, while students of agriculture and horticulture as well as fisheries will also find it.

Proper identification of aquatic weeds is of primary importance to their control. Aquatic plants that cause weed problems are divided into four groups: algae, floating weeds, emergent weeds (foliage above water) and submerged weeds (majority of foliage below water).
Algae are the most common group of weeds in South Carolina ponds. Aquatic weeds are those unwanted plants which grow and complete their life cycle in water and cause harm to aquatic environment directly and to related eco-environment relatively.
