DAGG ET AL.: DISTRIBUTION OF COPEPOD NAUPLII 



Table 2. — Regional comparisons of naupliar concentrations during 

 cruise I. Samples were collected by 2 methods: whole water sam- 

 ples were collected with Niskin bottles, and 64 (i.m mesh nets were 

 used to collect the net caught samples.

Table 3. — Onshore-offshore comparisons of naupliar concentra- 

 tions from the upper 10 m of each station. Tests for cruise I are 

 based on naupliar concentrations from all 3 regions pooled then 

 separated into 3 depth categories. During cruises II and III. nauplii 

 were only collected from the Mississippi River delta region.

Figure 2. — Naupliar concentrations (number/liter) from selected stations near the 50 m isobath on the Texas continental 

 shelf (a, station IV-1), the Louisiana Shelf (b, station IV-2, c, stations II-l, II-2, II-3), and the northwest Florida shelf (d,
