Grouper Fish

Stretching local and international market demand of fish kerapu (Grouper ) now increasing. One measure is the selling price of these reef fish are increasingly high. Imagine, one kg of duck or mouse grouper fish consumption size (about 500 grams per fish) at the level of farmers worth up to U.S. $ 48 - $ 52 per kg. For the tiger grouper, it costs USD 90-130 thousand per kg.

Although commodity prices of sea fish was very tempting, but the development of grouper fish cultivation in Indonesisa still underdeveloped. According to researchers from the Institute for Public Service grouper Aquaculture Karawang in West Java, Muh Abdul Rahman, hatchery technology for grouper new mass developed in the last fifteen years. "There are still many things that have not mastered the technology,
More Graduates Post-Graduate Institute Pertanian Bogor (IPB) is of the opinion, hatchery technology is not a major problem of farmers is often the seed. The issue that often arises is the stability of sales both in the amount of absorption of low seed and the selling price continues to decline. "Beginning in 2010 the price of tiger grouper fingerlings range from Rp 1,100 per head, but today only around Rp 700 per fish,
He considered, this occurs because the seedling growth was not balanced development of magnifying. As a result, sometimes a lot of seeds produced by society can not be absorbed by the farmers.
Participate opinion about the constraints expressed by the Chairman of the Forum Communications Kerapu Lampung, Build Sitepu. For Wake, the main obstacle pembenih grouper is operating capital in the business cultivation is high. According to him, the bank is "cautious" in giving credit to pembenih.
Wake up rate, it was thought that the fish farmers equated with fishermen who always helped so no feed back (reciprocal) for banks. "Actually, one thing to remember, people who do not have the capital he might not be a grouper fish farmers, as most who play in the grouper have other income sources," he said firmly.
From here Wake up expecting any breakthrough into banking, because the business opportunity is still quite large. "Now it is generally farmers rearing grouper only fill 40% of the total mapped Keramba cage (KJA) and 60% are still empty," he said.

Low Production
Not only pembenih who feel the lack of capital, farmers also feel the same magnification. This is stated by Ahmad Haerudin, cultivators in the Island Grill kerpau Thousand Islands district of Jakarta. Another problem is the supply of seeds that are still lacking.
This condition was recognized by Rahman. He judged the cause of low seed production of grouper fish from hatcheries (hatchery), among others, because of the nature of cannibals that much happening on stage juvenile (post-rearing the larvae) until the seeds are ready to stocking.
In addition, continued Rahman, SR (Survival Rate / survival rate) for grouper hatchery (hatchery) is also lower than when the enlargement, they are vulnerable to environmental changes. "Coupled with the mastery of hatchery technology that has not really steady," he said.
Rahman explains, today generally duck and tiger grouper hatchery average SR of 10% per cycle. Although SR grouper hatchery low, but still profitable (see table analysis of the business).
The same thing is said Wake. "SR at the hatchery is lower than the enlargement due to many factors, such as small fish, feed quality should be good, its durability is still lacking, so easily affected by death," he said
He pointed out, the vessel volume of 10 tons of 100 000 eggs filled grains, could survive 2-5% of total eggs that hatched just been great. "In fact sometimes fail all, therefore, need careful calculation of the technicians," added the man who had started the business in early 2010 kerpu seeding this.
Wake added that in general the issue is not as difficult as grouper seed first. "In eastern Indonesia now many hatcheries. Not like before, only Situbondo East Java and Bali alone, "said Wake. According to Rahman, for Situbondo and Bali could produce grouper seed duck 100 thousand - 150 thousand heads (size 5 cm), while for tiger grouper seed to produce between 1.5 - 2.5 million individuals per month.
Rahman added, for business ducks rearing grouper grouper production cost of about USD 125 thousand per head (average size of 500 grams). This means with grouper harag duck until Rp 500 thousand per kgnya, can dihuting keuntungnya. "Break-even value for the business of rearing grouper can be achieved with a minimum of 60% at harvest SR
