    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: For the successful breeding of western white shrimps (Litopenaeus vannamei) brooders (females and males), we used cuttle fish (Sepia pharaonis) and sand worm (Perinereis nuntica) of Persian Gulf as principle feeds, 3 times a day, and from cow livier and edible bivalve meat (Solen brevis) of Persian Gulf, as secondary feeds, 1 time a day. Nutritional value of Sepia pharaonis, Perinereis nuntica and Solen brevis, with determination of the amount of fatty acids such as arachidonic acid (20:4n-6), stearic acid (18:00), oleic acid (18:1n-9), palmitic acid, palmitoleic acid (16:1n-7), eicosapentaenoic acid (20:5n-3) and docosahexaenoic acid, essential amino acids inclusive arginine, lysine, leucine, isoleusine, threonine, valine, histidine, phenylalanine, methionine, tryptophane and crude protein, crude fat, crude fiber, ash and moisture were done in laboratory. The results showed that, the amount of essential amino acides and nonessential amino acides (in the more causes) in Sepia pharaonis were more than Solen brevis and in Solen brevis more than Perinereis nuntica. Only nonessential amino acides, glysine and alanine in Solen brevis were more than Sepia pharaonis. Also in chemical analysis of wet feeds determined that, crude protein percent in cattle fish was 2.9 times and 2.2 times more than Solen brevis and Perinereis nuntica, respectively. The crude fat in cattle fish was 2.1 times and 1.6 times more than Solen brevis and Perinereis nuntica respectively. Tottaly, the amount of essential fatty acides in Sepia pharaonis and Perinereis nuntica were more than Solen brevis, and in Sepia pharaonis and Perinereis nuntica were almost, equal. Total lipids of Sepia pharaonis, Perinereis nuntica and Solen brevis determined 7.92, 5.90 and 3.63 percent respectively. Totally the percent of fatty acids in cattle fish and Perinereis nuntica is almost equal and was more than Solen brevis meat. We can noted that, the Sepia pharaonis and Perinereis nuntica are suitable as principle feed and Solen brevis and cow livier, as secondary feed for L.vannamei broodstock maturation.

    Environmental risk assessment of the activity of specific pathogen free shrimp production centers (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study is a part of the national and technology master plan entitled "Attain to technical knowledge of specific pathogen free shrimp production and cut off to dependence on foreign products". The goals of this work were to assess and analysis the risk factors of production of specific pathogen free Litopenaeus vannamei shrimp in its all stages (broodstocking, laravl production, shrimp farming, feeding and water quality), determining the pattern of outcomes monitoring, management and control of outcomes from April 2012 to September 2015 in Bandargah research station and Persian Gulf SPF Shrimp research station and their environment, belonging to Shrimp Research Center, located in Bushehr. Identification and screening of risk factors have been done based on Environment Aspect and Effect Analysis method, (EA)2, using a fine statement questionnaire and quantification of risks. The number of identified risk factors in Bandargah research station was 15 while it was 13 in Persian Gulf SPF Shrimp research station. The more number of risk factors in Bandargah station in respect to its number in Persian Gulf station is might due to lower level of biosecurity, physical structure and aging of Bandargah station and existence of two possible source of contamination, the Bushehr nuclear power plant pollutants and Bandargah fishing harbor, near to the station. On the basis of results, the maximum values of APN in Bandargah station was 42 while it was 30 in Persian Gulf station. These results revealed that the level of risk in Bandargah station is lower than that in Persian Gulf station. The most probable risks in both studied research stations are related to transmission of pathogens in shrimp feeding and water intake pollution.

    Investigation of two crop culture of western white shrimp (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Two crop culture of western white shrimp with 2 treatments and 2 replicates in each treatments in earthen ponds with area 0.4 hectares at a density of 20 pl 18 in each square meter were done. For the culture of shrimp in the second stage, the post larvae cultured in nursery pond with area of 0.25 hectare, and density of 96 post larvae in each square meter, and then transfer to the rearing ponds. In each pond, 2 aerators with potency of 3 horsepower fixed. Every day horsepower clarified at 21p.m. to 23 p.m and out at 6 a.m to 7 a.m. The first stage of culture begun in 19 April with pl 18. The yield pick-up after 96 days. The stocking of pl in the nursery ponds was done in 25 July with pl16 and after 38 days hunted and transferred to second stage culture. The second culture was done in 1 September and pick-up after 65 days. For feeding of shrimps we used commercial food numbers 4001 until 4006. In the first mount the feeding of shrimps were done as blind feed and then with the shrimps biomass and with research of feeding trays. Water temperature, dissolved oxygen and pH daily in 2 times at the morning (6 a.m) and evening (at 15 p.m) and the salinity, transparency and water depth 1 time daily measured. In the first culture period (96 days), the mean weight, length, daily weight gain, FCR, survival percent shrimp production were 14.03 gr, 12.08 cm, 0.15 gr, 1.02 gr, 92 percent and 2132 kilograms and in the second culture period (65 days) 14.55 gr, 12.48 cm, 0.22 gr, 0.84, 73 percent and 2675 kilogarms measuered respectively. Totally, in the second period culture the initial weight of shrimps was higher than the first period culture 1.95 gr and 0.008 gr respectively, therefore growth indexes in the second period were better than the first culture period. Coefficient of determination of weight and lenth of shrimps with increase of cultue days, in the first and second culture periods, in the total cases the number were higher than 0.97. This shown that the role of increase of days on the increase of weight and lenth is higher than 97 percent. Also, determination of product moment, showed that there is very strong correlation between increase of days and increase of weight and lenth and between weight and lenth (0.97 to 0.99).

    Details
    Publication Date: 2021-05-19
    Description: The effects of one diet contain of 42 percent soybean meal (experimental treatment with 38 percent crude protein) in comparison with commercial diet (control treatment with 39 percent crud protein) at 6 earthen ponds, each one with the area of 0.4 ha, ( 2 treatments and 3 replicates in each treatment) on growth indexes of western white shrimp (Litopenaeusvannamei) was determined. The initial weight of post larvae was 0.008±0.001g, with density of 25 ind/m2 . The mean of culture periode in the experimental treatment and control treatment was 115 dayes, The mean of growth rate (GR) in the experimental treatment and control treatment was 15.70±0.88g and 15.60±0.52 g, respectively and significant statistically difference was between those (p〈0.05). The food conversion ratio (FCR), in the experimental treatment and control treatment was 1.80 ±0.08g and 1.76±0.06 g, respectively, and significant statiscally difference was between those (p〈0.05). Specific growth rate (SGR) in the experimental treatment and control treatment was 2.38 ±0.03 percent and 2.38 ±0.04 percent, respectivelly and significant statiscally difference was between those (p〈0.05). The average daily weight gain (ADG), in the experimental treatment and control treatment was 0.136 ±0.007g and 0.135±0.004 g respectivelly, and no significant statistically difference was between those (p〉0.05).The net protein utilization (NPU) in the experimental treatment and control treatment was 17.05 ±0.38 percent and 11.80±0.26 percent respectivelly, and significant statistically difference was between those (p〈0.05). The yield of shrimp in experimental treatment and control treatment was 2853.58 ±64.14 kg/ha and 2864.83±168.57kg/ha respectivelly, and significant statistically difference was between those (p〈0.05). The survival in the experimental treatment and control treatment was 91 ±1.78 percent and 92±2.41 percent, and no significant statiscally difference was between those (p〉0.05).The amount of diet consumption, in the experimental treatment and control treatment was 5144±112.23 kg and 5055±59.77 kg respectivelly, and significant statistically difference was between those (p〈0.05). The price of 1 kg of plant diet and commercial diet computed 34.000 rials and 43.000 rials respectively. In the shrimp body analysis, crude protein percent, in the experimental treatment was more than control treatment and significant statistically difference was computed between those (p〈0.05). Totally, the use of plant protein for the feeding of L.vannamei in the earthen pond, can decrease the cost of plant diet, 20 percent lower than commercial diet.
