Veliger larvae of molluscs and some annelid larvae capture food with opposed bands of cilia (Hatschek, 1878, 1880a, b, 1885; Nielsen, 1987; Hansen, 1993; Pernet et al., 2015; Pernet, 2018).
After reaching the veliger (D-larva) stage, larvae were fed with Isochysis galbana at between 50 and 300 cells [[micro]L.sup.-1] (Ferreira-Arrieta et al.
At the late trochophore or early veliger stage, the shell gland cells begin secretion [33].
Other research showed considerable spatial variation in dreissenid colonization due to differences in hydrology (Nalepa, 1994), which seems to create refuges by reducing veliger access to particular areas (McGoldrick et al., 2009).
Veliger Sampling--We used a student plankton net with 63-[micro]m mesh and a 127-mm mouth (Wildco[R], Yulee, Florida) to sample veligers.
The D-shaped larvae of the veliger were transparent with visible granules after 24 hours fertilization until day-5.
(3) After 24 hours, the first larval shell forms as a D-shaped veliger, which lasts for 2-3 days.
The trochophore (free-swimming larva with cilia) and the veliger (second larval stage seen in the diagram above with beginnings of foot, shell, and mantle) bear faint resemblances to their end product, the mature bivalve mollusk that forms the basis of a tasty meal.
Video taping was used in addition to visual observations to identify fifty random larvae as preyeliger, veliger with dark shells, veliger with light shells, or abnormal.
The former issue relates directly to the veliger larval ecology and peculiar dynamics of bivalve recruitment, which includes two phases - primary and secondary recruitment.
