Title Studies on larval euphausiids from the southwest coast of India with notes on their developmental pathways and breeding seasons
 
Creator Mathew, K J
 
Subject Phytoplanktons
 
Description In spite of the exhaustive studies done the world over on the larval euphausiids, the developmental pathways
of several species remain unknown or partly understood. The fact that larval euphausiids form a sizable
portion of the zooplankton in the sea makes a study of the larval biology more important. A large number
of zooplankton samples collected from the southwest coast of India have been examined for the occurrence
and the developmental stages of some major species of euphausiids. As a result of the studies the complete
post-naupliar stages of l'seudeupausia latifrons, Euphausia diomedeae, E. sibogae, E. lenera, Nematoscelis gracilis,
Stylocheiron armatum and S. affine have been obtained. The full complement of post-naupliar stages
of S. affine has been identified and the developmental pathway has been traced for the first time. Critical discussions
have been made in the article on the various life history stages of important species. A study on the
occurrence and abundance of the larval stages in the different months have enabled to understand the active
breeding seasons of five of the species. Thus it has been found that Pseudeuphausia latifrons, E diomedeae
and S. armatum have an active breeding season from December to April while E. sibogae and S. affine have it
from August to December and October to February respectively. S. affine has been found to be a continuous
breeder.
