Description Not Available
A two-dimensional hydrodynamic and particle
tracking model was used to estimate the dispersion and
retention of barnacle larvae from their possible spawning
sites in a tropical monsoon-influenced estuarine system
(central west coast of India). Validation of the hydrodynamic
simulations yielded a good match with field measurements.
The pattern of larval dispersal in the region
varied with the winds and currents. The seasonal changes
in abundance could be attributed to physical forcing and
weather conditions. The extent of barnacle larval dispersal
from spawning sites varied from 10 to 78 km for different
sites and seasons. During a 24-h cycle, the larval abundance
showed one to two peaks in the estuarine area. The
increased larval abundance is favored by the flood currents,
pushing the larvae into the estuary. Physical forcing in the
region helps in transport of the larvae from their spawning
sites hugging to the coast and contributing to the population
within the estuary. Field observations and numerical
experiments suggest the occurrence of higher larval abundance
in the estuary during post-monsoon. The dispersal
pattern indicated that the barnacle population present in the
estuary is well mixed, and with a seasonally changing
pattern.
