POLYCULTURE EXPERIMENTS OF POMPANO Trachinotus carolinus (CARANGIDAE) AND SPOTTED RED SHRIMP Penaeus brasiliensis (PENAEIDAE) IN CONCRETE PONDS, MARGARITA ISLAND, VENEZUELA

Abstract

Since 1978, polyculture experiments of pompano (Trachinotus carolinus) and shrimp have been conducted in the Centro de Investigaciones Cientificas, Universidad de Oriente, Venezuela. Experiments are carried out in circular concrete ponds (28 m2) with running seawater (salinity 37-39 ppt and temperature 26.4-30.9OC) and constant aeration. In the first experiment (September-December 1978) pompano and shrimp were stocked at a density of 10/m2 and were fed with Tivela mactroides (Mollusca, Pelecipoda) "guacuco" pellet of 60% crude protein. Pompano 0.225 0.1 g reached after 75 days 40.6525.6 g with food conversion of 6.59 and 17.14% survival; shrimp 1.3k0.4 g reached a weight of 5.7k0.9 g and 2.68% survival during 75 days. The common food conversion was 7.57. with a false bottom. Pompano and shrimp were stocked at densities of 5 and 10/m2 respectively, and were fed with a pellet named GSCA (42.8% crude protein). Pompano 4.0fl.l g reached 62.1k10.3 g after 75 days of culture, the food conversion and survival being 3.1 and 64.29%, respectively. Shrimp stocked at 3.620.6 g reached 8.951.8 g after 75 days, and feed conversion was 10.7 with 54% survival. The common feed conversion for pompano and shrimp was 6.6. After 75 days of culture the high mortality of pompano w a s due to the infection of branchial parasites, the protozoa Amyloodinium ocellatum and the trematode Bicotylophora trachinoti.The second experiment (June-August 1981) was carried out in tanks 'Mailing address: Apartado Postal 321, Porlamar 6301, Isla Margarita, Venezuela.

The status of Florida pompano, Trachinotus carolinus, as a commercially ready species for U.S. marine aquaculture

“…In addition, commercial tank-based production was evaluated in the Dominican Republic as well as in Florida (McMaster, 1988). In the late 1970s, pond-based polyculture of pompano and shrimp was assessed in Alabama (Tatum & Trimble, 1978;Trimble, 1980), and in the late 1970s and early 1980s work in Venezuela evaluated polyculture of pompano and shrimp using seawater tanks (Gomez & Scelzo, 1982) as well as production of pompano in floating cages (Gomez & Cervigon, 1987).…”

Production Characteristics and Body Composition of Florida Pompano Reared to Market Size at Two Different Densities in Low‐Salinity Recirculating Aquaculture Systems

“…Research conducted during this time period focused largely on developing production methods in various culture systems, including ponds (Berry and Iverson 1967;Moe et al 1968;Cuevas 1978;Tatum and Trimble 1978), in-pond cages (Marcello and Strawn 1972;Swingle 1972;Tatum 1972Tatum , 1973Smith 1973), and flow-through tanks (Iverson and Berry 1969;Gomez and Scelzo 1982). A common thread of the results of these studies was poor growth and feed conversion of fish greater than 200 g, usually coupled with poor survival, resulting in the inability to produce market-size fish (.450 g).…”

Amino Acid Availability of Soybean Meal for Florida Pompano

“…Despite interest in commercial aquaculture of Florida pompano since the 1960s, relatively limited information on the nutritional needs of this species is available. During the last 40 years of aquaculture efforts, Florida pompano have been fed groundfish (Iverson and Berry 1969;Finucane 1970a;Tatum 1972;Smith 1973), commercial fisheries bycatch (Berry and Iverson 1967;Moe et al 1968;Jory et al 1985), laboratory-prepared diets (Gomez and Scelzo 1982;Riche 2009), and a variety of commercial fish feeds (Iverson and Berry 1969;Finucane 1970aFinucane , 1970bSwingle 1972;Tatum 1972;Smith 1973;Holt and Strawn 1977;Tatum and Trimble 1978;Trimble 1980), with varying degrees of success. As research has increased our knowledge of the nutritional requirements of a growing number of fishes, better diets for marine species have been developed and some of these diets have been used successfully in Florida pompano growth trials (Williams et al 1985;Lazo et al 1998;Heilman and Spieler 1999;Weirich et al , 2009.…”
