CONSTRUCTION, OPERATING COSTS AND CASH FLOW TEMPLATES FOR CATFISH (FOOD FISH) PRODUCTION SYSTEMS PESCAT 15 Introduction One of the first things potential catfish producers should do prior to making a major investment in a new operation is to evaluate the financial feasibility of the proposed project. This Fact Sheet provides descriptions of some typical commercial catfish production systems found throughout the southern states. Templates presented here estimate the total investments, debt servicing requirements, annual operating budgets and cash flows for turn-key production enterprises. An analysis also illustrates the sensitivity of systems to changes in prices, costs and production relationships. These templates are available as spreadsheet software in Microsoft Excel Workbook and Lotus .WK3 file formats. Data from published sources as well as directly from producers involved in building and operating facilities are included to provide you a start in developing your own customized budgets. Production Systems You can use these spreadsheets to characterize three basic types of commercial catfish production systems: watershed ponds and ponds with a dependable water supply (well, lake or stream) are conventional production systems, while recirculating systems use more intensive technologies. Two other types of systems, cages and raceways, are not specifically described here, but could be characterized by modifying spreadsheets provided here. Each system has definable production, marketing and financial management issues. You will find detailed descriptions of production and marketing management requirements for systems such as these in several sources (see appendix). However, few of these resources address in detail the potential costs and returns of constructing and operating these systems.

Harvesting, Handling, Storage Pest Control: Weeds Insects Diseases Taxonomists have only recently begun to agree regarding classification of the domesticated species of Capsicum . Although five species are described, only two, C. annuum and C. frutescens have any significance commercially in the U.S.A. Early species separation on the basis of fruit shape, color and position are of little taxonomic value. Flower and seed color, shape of the calyx, the number of flowers per node and their orientation, are the primary separating characteristics. A simple key to identifying the five domesticated species of Capsicum may be found on page 1996 of "Peppers of the Worldan Identification Guide" by Dave DeWitt and Paul W. Bosland, Ten Speed Press, PO Box 7123, Berkeley, CA 97407.

Soft-Shell Crayfish: A New Crop for the Midwest Paul B. Brown AQUACULTURE Culture Economics and Marketing METHODOLOGY ... Fig. 1 Crayfish production can be divided into two distinct segments: hard- and soft-shell production (Huner 1990; Huner and Romaire 1990). Hard-shell producers market tail meat, similar to shrimp production, while soft-shell producers market the entire body, similar to soft-shell crab production. Soft-shell production requires a dependable source of relatively large, hard-shell crayfish. Studies conducted in our laboratory have indicated significant potential for pond production of native species for the tail-meat market ( Table 1 ). In our first attempt at producing the northern or fantail crayfish ( Orconectes viriles ), production levels were dependent on initial stocking strategy, but ranged from 323 to 807 kg/ha when fed agricultural forages (Brown et al. 1990), which compares favorably with average production levels in the South of 545 to 691 kg/ha (Roberts and Harper 1988). That initial study and two regional symposia on crayfish culture stimulated a great deal of interest in crayfish and construction of ponds was initiated. The next step in providing opportunities to midwestern farmers is evaluation of soft-shell production. AQUACULTURE Culture Economics and Marketing Soft-shell producers in the South purchase crayfish for $0.07 to 0.50 per kg, transport those animals to controlled, indoor tanks, and wait for the animal to molt, which typically takes 1 to 4 weeks. Soft-shell crayfish retail for $1.80 to $3.60 per kg. Thus, the profit margin and relatively quick turnover of product entices many farmers into soft-shell production.

New Horticultural Crops for the Southeastern United States Mary Lamberts FRUIT CROPS Alabama Florida Georgia ... Table 3 There are many reasons for the upsurge in interest in new horticultural crops. One industry expert (Cook 1990) reported that during the period between 1978 and 1989, consumption of fresh produce in the United States expanded 23%. The retail produce industry is now worth $32 billion. While the aging of American consumers also is a factor which can lead to overall reduced food purchases, it also has the potential for proportional increases in fresh fruit and vegetable consumption. Americans between the ages of 55 and 64 consume 39% more fresh fruit and 34% more fresh vegetables than the national average. As consumers move into their peak income-earning years, they purchase more high-value products and look for greater diversity. According to Manning (1990), the American produce industry has been riding the crest of a powerful demographic wave which will flatten by the year 2000. Manning predicts that although the nutritional appeal of fresh fruits and vegetables will continue, health options for consumers will increase; growers will need to create more demand and retailers will need to be convinced that consumers will pay more for produce before raising wholesale prices.
