Study on propagation and breeding of Hamoun fish (shizothoraxzarudnyi) to one gram weight in earthen pond

Hamoun fish, Schizothorax zarudnyi, is an indigenous species of the eastern waters of Iran, which is exclusively found in this region. However recently drought occurrence in the Chahnimeh reservoirs (a semi natural water body) making them vulnerable to extinction. As an appropriate action to address this problem and according to the 3 side contract between Italian Government – UNDP - Islamic republic of Iran Government and the Italian government financial support to reduce poverty in the Province of Sistan-Baluchestan through the reinforcement and dissemination of aquaculture activities the project was developed at the Hamoun Research Unit by the Chahbahar Fisheries Research Center to record the breeding normative of 1 g weight larvae for restocking and other researching purposes. 331 broodstocks of the indigenous species Shizothorax zarudnyi weighing 800-2450 g were collected from the Chahnimeh reservoirs in early autumn, 2006. From 5/3/2007 (the project is supported and communicated on 2010) , Ovulation was stimulated with three stimulators; pituitary extract (3-6 mg kg-1 body weight), GnRH-A (20-30 mg kg-1 body weight) and anti dopamine (10-15 mg kg-1 body weight) that was given in 2-3 doses to breeders. Of 169 injected breeders , some were injected On mid March of 2007 (12-13 ºC water temperature) responded to the injection 25% ,while the rest were injected On April of 2008 (14-16 ºC water temperature) responded to the injection 65%. In the present project of 167 breeders 82 were female and 87 male. Totally 30 female breeders released their eggs in different stages. 20 female breeders released their eggs completely, 3 breeders released half of their eggs and 7 released 1/3 of their eggs. The male breeders just injected in the final dose of hormontrapy and all were ready for releasing sperms however the ovulation in female breeders occurs between 353-428 h ºC and after the final dose of injection. Ripe eggs were stripped from the females and fertilization was done by the dry method. Fertilized eggs were transferred to veis incubators and troughs. Incubation period for eggs differs and larvae hatch out after about 910 days at an average water temperature of 12.5 °C. Maintained at 13-14 °C, complete absorption of yolk sac in Shizothorax zarudnyi larvae occurred after 5-8 days. Larvae were fed with a mixture of powdered milk and egg yolk in this stage followed by decapsulated Artemia cysts and nauplii of Artemia and then on formulated starter diets used for carps. Because the ponds were not ready, larvae were maintained in troughs for about ten days before they were transferred to two 1200 m2 earthen ponds where they reached a body weight of about 1 g. They were then handed over to the Iranian Fisheries department in the region. Larvae were fed with the starter feed SFCO in the earthen ponds. About 350 thousand larvae were stocked in two earthen ponds. Based on the results of present study and other studies we may conclude that artificial breeding in Schizothorax can be successfully achieved at 14-16 ºC in flow through systems using hormone therapy (combination of GnRha and anti dopamine) and larvae could be easily cultured in earthen ponds. However this species exhibits lower growth rates as compared to carps its high expenses could have an important role in economical feasible

An investigation effect of seaweeds as shrimp -feed ingredient for growth performance of Litopenaeus vannamei

In this project, the nutritional effects of Sargassum illicifolium Chabahar bay-Oman Sea, on growth and survival rates of whiteleg shrimp (Litopenaeus vannamei) were studied. The seaweed collected from 6 coastal area, rinsed, dried, powdered and measured the nutritional values in laboratory for surveying statistically. According to the high nutritional value of Tis coastal seaweed, this variate seaweed powder, replaced with protein resources (fish meal and Soy and Wheat) of whiteleg shrimp feed which was formulated by Havorash feed factory of Boshehr in four treatments (A: as control without any replacement) B: with 5%, C: 10 % and D: 15% seaweed replacement, each with three replicates in order to obtain isonitrogenus 33% CP., and Isocaloric (13% fat and 15% carbohydrate) feed. The weighed milled ingredients were carefully mixed using a laboratory food mixer. The mixtures were primed with 30% hot water to yield a suitable pulp. Wet diets were made into 2 mm pellet size and dried at 40 °C in a drying cabinet and maintained in standard condition which was used according to daily need shrimp, calculated by each 10 days biometry. Water stability and absorbtion capacity of the pellets in sea water were measured and compared statistically. Juvenile shrimps (Initial body weight =3 g) brought from Jask hatchery, acclimazed for one week in Chabahar hatchery condition and feeding daily 3-5% body weight. Abiotical parameters and weight and length biometrics were measured two days and 10 days, respectively. After 45 days and final biometry, FCR, CF, SGR, caracas analysis, muscle colourimetery with HPLC were done, tasted with pp Plot for determining the parametric data and statistically differences using one – way ANOVA, Duncan test of SPSS software. The Tis coastal seaweed with 9.8% CP, 2% lipid and 23% carbohydrate had higher nutritional value compared to the other gathered seaweed. Also amino acid and fatty acid profiles, vitamins and minerals were measured in all seaweed samples each, with three replications. As result, the water stability of D feed treatment in seawater (98%) and C (97%) had statistical differences with A and B (95% stability) (P0.05) but Cholestrol content of, showed differences between all, significantly (P<0.05) which was the highest (121.68±12.12) in D and the lowest in A (147.92±11.02). Feed treatment D and C performed colour changes pink partial orang and pink in shrimp muscle with no any difference compared to white and none colour in shrimp were fed B and A feed treatments . It seems this colour changing can be playing a major role in market acceptability

Fisebility study of collection and rearing of proleus stage of lobster (Panolirus homarus) in the cement tanks

The present study was carried out from late October2010 to end of June 2011. Executive operations were done in two stages; proleus catching from the sea and stocking/rearing them in a control conditions. Totally, it took 8 months from start to finish. The research objectives were; - Proleus catching techniques achievement. -Proleus keeping, stoking and rearing achievement. 32 pieces of proleus and post-proleus were collected by special installed collectors at the beneath of the sea. They were stocked after adaptation and initially biometry. In order to stocking, two 4th-tone tanks (one for proleus stage and another one for post-proleus stage) were applied. 0.77 gram and 11.8 gram was recorded as average weighted for proleus and post- proleus, respectively. Four stations were chosen for collecting of require samples. They were starched from west side of Ramin’s Jetty toward east. 84% of the samples were caught from the station two, using sandwich collectors. Collector’s efficiencies were compared to each others, in this study. A significant difference was observed between the sandwich collectors efficiency with the other collectors (p0.05). Comparison of the proleus abundance between stations showed a significant difference between station 2 and other stations, but there wasn’t any sig. difference between the stations number 2, 3 and 4, together (p>0.05). The samples were fed by fish waste, bivalves and squid. The amount of larval requirement food was calculated based on 15% of their body weight. During breading period, 50% of the rearing tanks water was exchanged, daily. Total weight, total length and carapace length was measured, monthly. 0.6 gram, 5.5 mm and 1 mm was recorded for mean total weight, mean total length and mean carapace length for proleus and 18.3 gram, 25.4 mm and 8 mm was recorded for mean total weight, mean total length and mean carapace length for post-proleus. According to the results, can be realized that growth rate in post-proleus was much faster than the growth rate of proleus. Finally, comparison of the total weight, total length and carapace length between proleus and post-proleus were showed a sig. differences between the two reared groups (p>0.05)

Possibility of the pond culture of Asian sea bass, lates calcarifer in Gwadar farm , Sistan & Baloochestan

In the present study, the possibility of marine culture of Asian sea bass in the shrimp earthen ponds located in the Gwadar region (coastal area of Oman Sea, southeastern of Iran) was investigated. To this end, Asian sea bass frys reared for 7 months including 1 month nursery and 6 months growth-period. During the culturing periods, fish were feed ad libitum by various commercial rainbow trout diets based on fish growth stages. After nursery period, the average weight of 11.05±1.5 g and survival percent of 65 % were obtained for fish. During the growth-out period, the average weight increased continually from 31.4±4.7 g in late June to 252.1±30 g at the end of growth-out period in late Dec. Also, the highest values of monthly weight gain yielded during August, Sept and Oct when fish had the average weight range of (76.9±14.4)-(188.1±12.8) g. The values of monthly feed conversion ratio (FCR) were low and similar from July to Oct and then increased in Nov and Dec. The values of total monthly feed intake (FI) increased continually from July to Oct and then with a decrease in Nov, increased again in Dec. The values of survival percent after nursery and growth-out period were 65 % and 66% respectively. Also, the average of monthly FCR, FCR at the time of fish harvesting, total FI and total harvested biomass were 1.36, 2.5, 630.5 kg and 325 kg. in conclusion, the pond culture of Asian sea bass with marine water results appropriate survival and growth rates so that fish (11.05±1.5 g) obtained marketable weight (252.1±30 g) during 6 months culturing period. It seems that first-half of year in Gwadar area is more suitable for sea bass culture since this time periods results better FCR ( fed by rainbow trout feed) and has economic justification. Also, with regular sorting operation and providing of species-specific feed for Asian sea bass can increase the Production per Unit Area

Study and relocation of corals in developing area of Shahid Beheshty port, Chabahar

The conservation of coral colonies is very vital for marine organisms and human. In Chabahar Bay, the coral reefs are in danger of destruction due to the development program of Shahid Beheshti Port. In this project, over 30,000 hard corals were transported to coast of Hotel Lipar an area at a distance of 3.5-4 kms far from Shahid Beheshti Port. Also, the new techniques were used for coral reattachment and transportation. The operation has done within expert divers and consultancy of Prof. Dr. Maikle Risk. Four methods performance as pailots. Since the corals are very sensitive to turbidity and suspended sediments from land reclamation and dredging projects, therefore appropriate measures should be conducted for conservation and recovery of them.37 patches in size 5×10 meters has built with concerete. Diffent sizes of corals were separated by mechanical tools and transported to new sites and reattachment on artificial sea bottom.Three monthes after the last reattachments monitored showed that %96.93 of corals were in good health. This success was the important achievement because of innovating coral carrier and mass coral relocation. At present, the coral relocation is suggested as a good method for recovery of coral reefs after a disturbance in condition of their native habitats

Identification of local microalgae & their evaluation as live food in aquaculture from Oman Sea

Microalgae are very important organisms in aquaculture as major live food in all growth stages of bivalve, some larval stages of crustaceans, some fishes and zooplankton. In this project with the knowledge that local algae can provide better nutritional balance for local animals. Microalgae were isolated, identified and evaluated for their nutritional value for the first time. Another aim of this research was to create phytoplankton culture collection (Bank) in the south of Iran. Water was sampled from Sistan and Baluchesta coasts, then isolation and purification process were carried out in the lab. Species identification was based on morphology and molecular analyses. rDNA was extracted from each strain after PCR, partial LSU-rDNA region were sequenced and compared with similar sequence from GenBank. In order to evaluate their nutritional properties, relative growth, fatty acids composition, total lipid, carbohydrate, protein, and some vitamins of each purified strain were determined. Totally 25 species were isolated and purified, of which 12 strains were recorded in GenBank and their nutritional potential were assessed. Dunaliella cf. bardawill, Isochrysis sp. Cheatoceros sp. Clorella cf. volgaris, Ochromonas sp. and Synechococcus sp. were the most important species research. Iranian strains were varied in their amount of protein (27-40%), carbohydrate (221%) and lipid (8-13%). Proportions of SFA (21-48%), MUFA (33-53%) and PUFA (11-28.5%) were varied among strains. The highest amount of PUFA and B3 vitamin were found in Clorella cf. vulgaris. The highest content of protein (40.12% dry wt) and total fatty acid concentration (30% dry wt) were found in Dunaliella cf. bardawil and Ochromonas strain(CHPO2) respectively. The maximum content of total fatty acid was observed in Ochromonas sp. (CHPO2). Cheatoceros sp. had higher relative growth rate in comparison with other species
