To determine the cellular and adaptations changes in mitochondria-rich cells under different salinities, Sparidentex hasta as a urihaline has been studied Comparison of propagation efficiency of sobaity (Sparidentex hasta) fish rearing with fish capture from the sea in circular spawning tank. Hastanecine; ; (-)-Hastanecine MW: g/mol MF: C8H15NO2 IUPAC name: (1R,7S,8S)(hydroxymethyl)-2,3,5,6,7,8-hexahydro-1H-pyrrol.

It is a silvery fish with tender flesh and a rich flavor.
Sobaity bream has been a table delicacy for the Arabs for more than a century Kitto, Sparidentex hasta, any reduction in feed cost sparidentex hasta improvement in feed efficiency would have a positive impact in reducing production cost and maximizing profit of the fish farming enterprise.
Thus, cost-effective and high performing commercial feeds have been developed by various feed companies for culturing valuable marine species.
Characteristics of some digestive enzymes in sobaity, Sparidentex hasta
Since no fish meal is produced in Kuwait, use of imported fish meal in aquafeed in Kuwait may not be cost effective. Different commercial feeds available in the world market are being imported to Kuwait for fry rearing and grow-out operations by the Aquaculture Program at KISR.
Hence, the immediate priority was given sparidentex hasta find a cost-effective feed from the available commercial diets to start with the commercialization of sobaity.
Since formulation, testing, and development of a new diet is a long process, this study evaluated three commercial feeds, namely, Arasco Saudi ArabiaBiomar Greeceand Skretting Turkeyalong with a local trash sparidentex hasta feed for commercial culturing of sobaity bream in Kuwait.

sparidentex hasta Materials and methods 2. The tanks were covered with nets to prevent the fish from jumping out. A continuous oxygen supply in the experimental tanks was maintained through air stones.
Source of fish sparidentex hasta acclimation and sampling Uniform-sized grow-out sobaity bream There were three replicates for each treatment and the stocking density was 20 fish per tank.
At the start of the experiment, individual fish in each tank was measured for length and weight. Four-weekly bulk sampling was done using an electronic balance to monitor fish growth.
During the sampling period, the water in each tank was reduced, and quinaldine was used to anesthetize the sparidentex hasta. All of the sparidentex hasta in each tank were bulk weighed using an electronic balance.
IUCN Red List of Threatened Species
Sparidentex hasta sampling, fish in the tanks were counted numerically, and each tank was cleaned and washed before the fish were released back into the tanks. Any mortality of fish was recorded.
At the beginning of the experiment, five fish from the stock were collected as sparidentex hasta sample, and at the end of the experiment, three fish from each replicate tank were collected as final sample for proximate and fatty acid composition analysis.

The skin and boneless fillets from both sides of the fish were sparidentex hasta, pooled, ground, and freeze-dried for chemical analysis.
The rest of the fish were kept in their respective tanks, and feeding was continued until the organoleptic test was done to evaluate the fillet quality compared sparidentex hasta that of the wild sobaity.
Experimental feeds and feeding Three different commercial feeds such as Biomar 3. For confidentiality, these commercial feeds were randomly given the code names diet 1, diet 2, and diet 3, which were known only to the investigating staffs. Since the feed pellet sizes were smaller compared to the fish size, they were repelleted to a size of 4.
Sparidentex hasta trash fish was used as the sparidentex hasta.
The trash fish were bought in bulk and kept deep frozen.
