Spat grew better at the low stocking density, demonstrating that a higher stocking density is not suitable.Īrcangeli G (2012) Focolai in Italia da OsHv-01 microvar: problema o opportunità?

A higher rate of mortality was initially observed in the L group (6.7% at t1) however, mortality in the H group was higher at later sampling dates, reaching the highest level at t4 (32.4%). Considering the time factor, oysters were significantly heavier (0.941 g P < 0.001) and longer (21.30 mm P < 0.001) at t5 than at any previous sampling time (t1–t4). 10.47 mm P < 0.001) in the L group compared to the H group. On the basis of the ANOVA analysis, spat were significantly heavier (0.352 vs. A total of 53,100 spat (weight 0.033 g, length 5 mm) were divided into seven cylinders at either high density (H 5055 oysters/cylinder, 167.3 g/cylinder) or low density (L 2530 oysters/cylinder, 83.7 g/cylinder). Lanterns were hung 6 m below the surface of the water in the Middle Adriatic Sea. Spat were reared at two stocking densities in polyvinyl chloride cylinders (10 cm diameter, 24 cm length) placed within lanterns composed of five levels (60 cm diameter, 11 cm height). A pregrowing trial was carried out using nursery-stage cupped oyster ( Crassostrea gigas) in order to evaluate weight, length, mortality, and final costs of spat grown in long-line aquaculture at different sampling times (t1–t5) over 81 days.
