Part of the common sea urchin gonads or eggs are used, both male and female gonads gonad. Irregular sea urchin has five gonads hanging along the inside interambulakral the aboral region. Depending
on environmental and genetic factors, young urchins can reach sexual
maturity around 1-2 years after the switch from larval stage to the
juvenile phase. Tripneutes gratilla from Bali having sex the first time at the ripe age of 2.5 years. After that gonadnya production declined. It is found also in the class lainny echinoids. Mature
gonads are very large, filling the empty space between the strands of
the intestine and extends from mid-aboral to reach the lantern of
Aristotle. Gonads are generally soft and slimy cooked texture. Such eggs are not desirable as fishery products. Eggs or gonad desired texture is compact, where this condition occurs when the phase pijah information. Urchin harvesting should be done at the time of gonad maturity index reaches a maximum or before the spawning season. Animals
that theoretically should be arrested are ever spawn at least once in
order to be able to breed animals before being caught, the California
red sea urchin (Strongylocentrotus fransciscanus) may only be harvested
once between the ages of 5-8 years. Whereas
in Echinus esculentus Shetland harvesting dilakuka usually from late
December to late February, exactly before the spawning season. Heavy
sea urchins typically achieve 25% of total body weight, depending on
population density and availability of adequate food in the wild. Harvesting should not be done if the average percentage of gonad is still below 10%. Most of the countries in America and Europe have started to develop the cultivation of this species. Although in its development, it is clear the difference between catches in marine products and eggs from the cultivation.
The main difference lies in the color and texture of the eggs produced. Color and texture are the two determining factor in quality and price of sea urchins. According
to Pearce et al (2004) that the sea urchins fed artificial feed can
produce large eggs, but eggs produced pale color (pale), while the color
of sea urchin eggs is much more natural catchment reddish yellow. This affects the selling price (www.beritaiptek.com). Shells
of certain types of sea urchins are covered with black pigment
stabil.Cairan fluid can be used as a mesh and skin coloring. Shells of sea urchins are also in demand as jewelery. While
processing the rest of the organs of sea urchins is usually a shell and
internal organs (viscera) can be further processed into fertilizer. Urchin
gonads are generally sold in a fresh condition, because it has the most
tinggi.Beberapa gonad quality criteria that affect the purchase price
at auction is a type, country of origin, color, texture, size,
appearance, freshness, and taste. Among the criteria are color, freshness and country of origin is an important factor in determining price. Based
on color, quality sea urchin gonads can be grouped into a very good
quality (Grade A) with yellow or orange gonads bright, good quality
(Grade B) with gonad color pink or pale yellow (cream) and poor quality
(reject) the gonad brown.
