Inrumentation in Intensive Aquaculture: Computerid Monitorig and Control in Round Pond Shrip Culture Background Paul K. Bienfang The Ocic Institute Aquaculture is widely recgnize as an industr which has very large growth potential for the United States. This growth is being driven by a consistently increasing demand for sefoo products in the face of leveling and/or declining fisheries catches from the wild. U.S. demands for seoo in excess of domestic supply have cause burgeoning importtion of sefoo products. Ths has resulted in ever increasing annual trde deficits in the area of fisheries and aquaculturay produce products. \ . Most of the aquaculturay produce sefoo imported to the U.S. comes from lesser develope countres (LDC). Support by low operating costs for land, labor and fee, aquaculture production has ben growing rapidly in such countres, providing them with export revenues and providing the additional supplies of seoo demanded by the U.S. market. Most of these LDC settings operate extensive production systems becuse the infrastrcture canot support the stabilty required by more intensive production systems. Within the last decde, increasing attntion has been directe at developing aquaculture systems within the U.S. which are ecnomicaly compatible with the business climate prevailing in our domestic settng. One of the foremost barers to market entr is the development of production systems which ca overcome the higher production costs and provide products at costs competitive with the foreign imports. This has involved focusing attention on the development of intensive production systems which produce more pounds of product per area per unit time. Indee, intensification is generaly recognize as being the principle opportunity for economic feasibilty of aquaculture withn the U. S. business climate. The growth of aquaculture in the Unite States has direct growth implications for several key attendant industres in addition to the commercial producers themselves. . The fees and instrument industres are only two which show promise for coat-taling on the increases in domestic aquaculture industr. Both of these areas represent mature industries having limited growth potential within the existing markets, yet both represent areas where the U.S. tehnology is some of the best in the world. Both industres also figure heavily in the nee for 83
intensification of domestic aquaculture, becuse both the quaity of fees and the requirements for system monitoring and management are requisite nees for the intensification procss. These conditions (Le., the growth of domestic aquaculture, the nee for intensive productions systems and the automate monitoring nees for controlled management of such systems) together with the effluent monitoring requirements for environmenta protetion, argue for the opportunities for a substatially increase market for marne instrmentation. As aquaculture grows, so wil the nee for instrmentation to automate many of the otherwise labor-intensive aspets of production. A critica component of intensive production systems is the development of automate monitoring systems to provide the enhance water quality maintenance required to mitigate the risks potentially assoiate with intensification. Computerized monitoring/management systems tae advantage of the U.S. technologica infrastructure to provide the required management of multiple intensive aquaculture production systems with a minimum of manpower. Such capabilty encourages domestic economic growth opportunities for both the aquaculture and electronics industres. Project Objectives The objectives of The Ocic Institute component are to inform both current and potential instrment uses in the aquaculture and fisheries areas of the available tehnology in marne instrmentation. Secondly, we want to improve the communication interface between these endusers and the instrment manufacturers. Thirdly, we wil survey the instrmentation uses and nees of those involved in stock enhancement activities. Project Tasks The project tasks to be performed during the seond yea include: 1. convening an international workshop at WAS '89 to document world state-of-thear in instrmentation uses and publish procings; 2. establishing a state-of-the-ar aquaculture monitoring demonstrtion system; 3. documenting aquaculture activities and instrmentation nees; apd -- 4. assessing the market for instrmentation technology in stock enhancement related areas. 84
