Commonly found in European lobsters (Homarus gammarus L) are unusual. The protruding rostrum between the eyes has several lateral teeth and usually on or more ventral teeth, which is not found in the European Lobster.

In H. americanus the ventral teeth on the rostrum are visible even in the first zoea larval stage (Helluy & Beltz, ).

A semi-quantitative assay is described for assessing the effectiveness of bait extracts for the lobster Homarus gammarus (L.), using an extract of the squid Loligo vulgaris Lamarck as a standard.

Fractionation of this extract indicated that, while no single component was as attractive to lobsters as the whole, the recombination of the various components yielded a solution which Cited by: • High survival if the lobster larvae are kept in single rooms through the live food period (85 - 91 %), compared to an open system (35 – 83 %).
