Abstract
The potential for integration of sandfish (Holothuria scabra) and snubnose pompano (Trachinotus blochii) culture was assessed in two experiments. Experiment 1 examined the effect of varying pompano:sandfish stocking density ratios (1:0.5, 1:1, 1:1.5 and pompano monoculture control) on growth, survival and sediment quality (measured by Total Organic Matter: TOM and Sediment Total Nitrogen: STN content) over 75 days. Experiment 2 applied the best density (1:1) determined from Experiment 1 to commercial-scale co-culture in 2 × 500 m 2 earthen ponds over 8 months. Mean pompano weight gain during Experiment 1 was 11.9% higher on average in co-culture across all treatments (70.5 ± 5.2 g cf. control: 59.7 ± 4.8 g), while sandfish performed better (11.6% increase) at density ratios of 1:0.5 and 1:1. Survival remained high (>91%) in all treatments. Absolute growth rates were 14.9% higher in co-culture for pompano, whereas fastest sandfish growth occurred at density ratios of 1:0.5 and 1:1 (10.3% and 11.2% higher cf. control, respectively). Sediment TOM and STN content reduced with increasing sandfish density (TOM: 55.6–46.1% and STN:62.3–34.5% lower cf. control). During Experiment 2 pompano and sandfish reached 494.5 ± 1.8 g and 393.0 ± 20.9 g, respectively; over 8 months from initial sizes of 2.53 ± 0.02 g and 5.49 ± 0.05 g. Specific growth rates averaged 2.20 ± 0.02 and 1.75 ± 0.03%/day. Sediment TOM and STN increased over the culture period. Results demonstrate high feasibility for co-culture of these species with improved pond sediment quality.
