Furthermore, a statistically significant depth-sampling day interaction was noted, with a depth-graduation, of settled spat abundance (abundance at 8 m >4 m >1 m depth) during the period from the 30th (beginning of June) to 105th day (mid-August) (Tukey's HSD test; P < 0.
The size of settled spat was similar for both species (Table 2; interaction of size x species; P > 0.
The results reported here agree with various other studies showing the best scallop spat settlement occurred near the seabed (Buestel et al.
Her daughter, who has washed dishes at El Vaquero, bused tables at Red Agave and waited on customers at June, has embraced her role as front-of-house manager at Carmelita Spats
Unfortunately, he passed away but I think it's important Spats
did come back at the right time.
Food quality and quantity are important factors for successful development of bivalve larvae and spat (Laing 1995, Gagne et al.
Another factor that may influence larval and spat development is the nutritional status of the broodstock (Utting & Millican 1998, Farias-Molina 2001).
The current study aimed to determine the effect of (1) ambient light, (2) periodicity of tank cleaning, (3) different diets and feeding regimes, and (4) broodstock conditioning on growth and productivity of spat of Nodipecten nodosus under hatchery conditions.
If successful, Palmer says Wakatu will eliminate the early mortality stages of spat, reduce mussel growth time from 18 to 12 months and increase mussel yield from 40 to 53 percent.
He says that if this is achieved pond-based spat production, together with selective breeding, will not only increase Wakatu's export earnings by 50 percent, it will open up wider implications for development across the aquaculture sector.
