These data represent the first reported study of Relative larval abundance was degree of stratification, although theĪssociation was weak. The only physical parameter associated with Larvae, with the possibility of a pulse of larvae from elsewhere toward Size-frequencyĭistributions of larvae indicate that these were 2 separate cohorts of Two pulses of larvae wereĬaptured, in March and late May to early June. Indicating at least some larval retention. More and larger larvae wereĬaptured in the inside and middle of the harbor than the outer harbor, Larvae were found consistently at the surface and Paired with molecular identification and sorting (FISH-CS)-was used toĭetermine the distribution of geoduck larvae over 4 mo at 3 stations in A novel approach time-integrating larval tube traps (Panopea generosa Gould 1850), a commercially important species found in Known about in situ larval distribution of Pacific geoduck clams Them, has limited many studies of larval distribution in the field,Įspecially for species that are less common. The patchiness ofĭispersing larvae, and the resources needed for sorting and identifying Parameterization of larval connectivity models. History is necessary for effective management of shellfish and Retrieved from ĪBSTRACT Realistic species-specific information about larval life
