Goldstripe sardinella
Encyclopedia
The goldstripe sardinella, Sardinella gibbosa, is a species of fish of the family Clupeidae
.
It is native to shallow tropical waters of the western Indo-Pacific
, living at depths down to 70 m, and being associated with coral reef
s. It grows up to 17 cm in length and forms large schools.
It is an important commercial fish, and is eaten dried, salted, boiled, or made into fish balls.
Reproduction
S. gibbosa have very unique eggs because they do not possess the wide perivitelline space (an important aspect to sardinella eggs). Some scientists do not consider this a true member of the Sardinella genus for this reason. The spawning season for these fish ranges from April to October. In this species there is a trend of smaller fish spawning earlier in the spawning season. Peak spawning occurs in June and July and this is followed by the older larger specimens which tend to move into the spawning areas later in the season.
Age Determination
The determination of age in this species has proved difficult because there are annulus present but it is very difficult to determine their true cause. These annulus which are present in the striae are often interrupted or indented. The spaces between striae are often lighter in color especially in comparison to the rest of the striated region of the scale. In comparison, salmon and trout form much more distinct annuli according to annuli forming closer to one another during different seasons of the year. In essence, the debate is whether these annuli are spawning rings or whether they develop as a result of some unknown cause and unknown time frame. This information is ineffective as a measure of the age of the fish until these issues are cleared and definitive.
Commercial Production
Dried Sardinella gibbosa is a favorite especially in Korean markets. These fish are advertised as Dried herring in Korea, England, Sweden and Canada. The process by which Vietnamese Gold Stripe Sardinella are made available includes being washed, steamed, sun dried, packed and preserved. . These fish are important in fisheries in parts of India and throughout Southeast Asia.
Distinguishing Features
Sardinella gibbosa have a relatively slender body, with 32-34 scutes and a below average number of gill rakers. They have unique, small perforations on the hind part of their scales along with a dark spot on the dorsal fin. The distribution of S. gibbosa indludes the Indo-West Pacific, East African coast, and a range from Madagascar to Indonesia. S. gibbosa are one of most abundant Sardinella in Indo West Pacific, and off the coast of Taiwan, Korea and Australia. Fisheries are most prominant in Southern parts of India, with markets throughout Southeast Asia

Coral reef
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny living animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps...
