    Evaluation of restocking program in north Alborz (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Gillan , Mazandaran and Gorgan provinces have temperate climate, thus they have more potential for aquatic animal culture. There are thousands hectare of lands for Aquaculure and fisheries in adjacent to Caspian Sea in this provinces. these areas(North alborz) have provided a favorable back ground for aquatic animal breeding and stock enhancement of species in the sea. As a result, this investigation executed during two stages (phases). At first stage, the goal of this project included the feasibility study and demonstrating the existing situation of fish stock enhancement activities in North Alborz area and second phase is to survey on distribution, and production activities of stock enhancing hatcheries as well as their constructions,and production time table. Survey was started frome 2006 to 2008 by using qestionaries in 7 hatcheries from tree provinces.results revieled that there are more than 10 species was subjected to restocking .Total releasing was about 300 millions of fry and finger lings in to the Caspian sea.

    Publication Date: 2021-05-19
    Description: 30000 juvenile Indian majour carps (Labeo Rohita,Cirhinus merigala, Catla catla) imported (2007 and 2008) and transferred to the earthen ponds in Astaneh Fisheries Research Station (Gilan ) and Sheiban Resaerch center (Khozestan) , In order to assess the viability of rearing fry up to 1 gram fingerlings under the climatic condition of north and south part of Iran . Growth parameters from the larval stage to 1 g were studied also .The fry with 300 mg weight, were released in to 3ponds.specimens were separated to tree experimental categories. fishes were fed with artificial food and also with the natural products of the ponds which were enriched with organic fertilizers, after being equally stocked in the ponds .During the experiment, oxygen level ,PH, turbidity, and temperature were measured . Monthly fry samples were taken, for weight and length biometrical analysis and also determination of the weight gain percentage, average daily growth rate, specific growth rate. Results have indicated adaptations and considerable growth in this species, with an increase from the initial weight of 300 mg to an average of 13.5±1.6 mg in 50 days period until the end of November for fingerlings.Catla was gain 1 g. during 15 day while Roho and Merigal were gain 1 g. during 14 and 10 days respectively. Results revealed that the Indian majour carps compatibility with the condition in Gilan province was succesfull and the combination of species and optimization of their compatibility specialy in other provinces like Sistan and Baluchestan were remind for futhre studies.

    Description: An experiment was conducted to evaluate the possibility of adaptation, growth and survival of Nile tilapia (Oreochromis niloticus) with 0.3g initial weight and red tilapia (Oreochromis sp.) with 0.7g initial weight in underground brackish water. Fry of Nile tilapia and red tilapia imported from Indonesia and after passing larviculture (25g) were examined separately in fiber glass tank by two replicate. Fish were fed at a restricted feeding program according to standard table during the light period. The results showed that some growth factors such as final weight, final length, daily growth rate, specific growth rate and weight gain in Nile tilapia were slightly higher than red tilapia but other factors such as survival and feed conversion rate in red tilapia were slightly higher than Nile tilapia. There were no significantly differences at 99% level among these factors. Length-weight relationship equation was w = 0.012×TL3.189 in Nile tilapia and w = 0.014×TL3.119 in red tilapia (r2 = 0.99), b value were 3.189 and 3.119 respectively in Nile and red tilapia representing isometric growth. According to the reliable growth and high survival rate (98%), it seems that both Nile and red tilapia could be good candidates for rearing in brackish water condition.

    Description: Nowadays, Litopenaeus vannamei are the most important species of farmed penaeidae shrimp in the world that is rapidly replacing native species in areas aquaculture. Due to demand increase for this species culture, shrimp displacement to different areas may be associated with some potential pathogens transferred to new areas farmed. Therefore, in this study were prepared bi-osecurity conditions for specific disease-free production of L. vannamei. Thereafter, three populations (Molokaei, High health and mix of Molokaei and High health) of the shrimp various reserves were detected base on origin and genetic indexes such as: observed heterozygosity, expected heterozygosity, allele frequency, coefficient inbreeding, genetic differentiation, genetic distance and genetic identity. On the other hand, epidemiological studies indicate non pathogens (viral, bacterial, fungal and parasitic) recognition of different populations selected in the quarantine salon. The bioassay results showed that the average weight and length of the populations of High health and Mix significantly greater than was a population of Molokaei. The shrimp populations were stocked in fiberglass tank (five ton) and were kept separated in the quarantine salon. During maintenance shrimp of populations in the quarantine salon were evaluated living and non-living pathogens with PCR, microbiology and biochemical methods. There is not any pathogens detection from shrimp populations stocking in the quarantine salon, so the shrimps were carried over to pond for broodstock culture of specific pathogenic free.
