Methods & Sampling

Dataset acquisition description

In this experiment, larval growth and metamorposis was tested using different food levels.

Larvae hatched on October 10, 2009 and ~50 were distributed into each tubs on 500mL filtered sea water (FSW). Because the greatest metamorphic success was in the Isochrysis galbana treatment during experiment 1, only that species was used in experiment 2. Three food densities were created high food (4 x 104 cells mL-1 ), low food (4 x 103 cells mL-1 ) plus an Unfed treatment in which larvae were raised in FSW.

Larvae were placed in settlement challenges at 6- and 8-day post-hatch. Procedures were as in the first experiment, except that on each day 15 larvae from each replicate container within each food treatment were pooled, then redistributed into three replicate containers with coral rubble in 200 mL FSW (total N = 45 larvae from each food treatment). Also, mortality was so high in the 6-day challenge that the challenge was terminated after 2 days rather than 3

Instruments

Hemocytometer

Supplied Name: hemocytometer

Supplied Description:

Investigators used a hemocytometer to count algal cells and calculate densities of phytoplankton stocks and amount of stock to add to containers for each treatment.

Instrument Type

Generic Name: Hemocytometer

Generic Description:

A hemocytometer is a small glass chamber, resembling a thick microscope slide, used for determining the number of cells per unit volume of a suspension. Originally used for performing blood cell counts, a hemocytometer can be used to count a variety of cell types in the laboratory. Also spelled as "haemocytometer". Description from:
