a small amount of oil. However, it is more preferred broiled crab cakes in terms of
consumer health. However, consumers think that fried or sautéed crab cakes are
even more delicious.

2.3.1.1 General Information About Marine Lobsters
Biology of Marine Lobsters
Lobster is one of the arthropod marine species and is important seafood due to its
interesting biology and high economic value. Since lobster is a very valuable flavour
worldwide, there are ongoing technical advances to ensure that stocks in all major
lobster producing countries remain sustainable for future generations. These include
the development of hatchery techniques for the development of fishery, which is
successful for the Homarus species and is in the experimental stage of rock lobster.
Lobsters are large crustaceans. Generally, they may vary in length from a few cm
to more than 60 cm. Like shrimps, lobsters have a well-developed and elongated
body and tail. In addition, the lobsters have a thicker shell. Lobsters are distinguished from shrimps by having a dorsoventrally depressed body, less developed
pleopods and thoracic sternum wide and distinct (Ng 1998). The lobster body is
divided into two parts. The first part is the body part consisting of the integrated
head and thorax, the second part is the abdomen and the tail consisting of six parts.
Head and thorax surrounding the shell is carapace.
The upper shell of the lobsters is flat. Behind the eyes are two pairs of spines. The
outer pair is very small. The lobster has two moving eyes, two antennas, six mouth
sections and 20 gills under the carapace. There are four or five teeth on the lateral
edge of the mouth. Two grooves extend from the end of the mouth and the middle
towards the middle edge of the shell. The abdomen is flat. Two pairs of arms and
with large claws. One of them is a cutting claw and the other is a catch claw equipped
with strong irregular teeth. The second and third pairs of arms are thinner. They also
have clamps. The lobsters are bluish black in colour and the top is spotted and the
bottom is greenish (Alpbaz 1993).
Most lobsters live in rocky and stony areas. They are especially hidden in intensive planktonic cavities. Some live on hard ground, while others are found among
mud, sand, and moss. But they do not bury themselves in the mud. Lobsters are
hidden in a large part of their time, looking for food for a very short time.
Lobsters reach maturity in the age of 4–6 years. Lobster mating occurs in the
summer, during the female’s moulting period. It is stated that mating can occur up
to day 12 even if the mating is usually 48 h after the moulting. Success in mating
