The objective of this study was to investigate themarketability of the Nile andred hybrid tilapia fillets which were reared at the Inland Saltwater Fish Research Center (Yazd, Iran). The fish samples were transferred to the National Fish Processing Research Center (Anzali, Guilan, Iran) andfish filleting was done manually. A questionnaire was designed based on the Central Location Test CLT to assess consumer’s attitudes. A 9-point hedonic scale (1 = extremely bad, 9 = extremely good) was applied for consumer survey. Fish loins papered from each fillet were deep fired in frying oil and presented to the 276 consumers in Tehran, Mazandaran and Guilan provinces. Proximate compositions of the samples were also determined. Results indicated that the tilapia fillets contained 18.8-19.3% protein, 1.5-1.6% fat, 77-78% moisture and 1.8- 1.9% ash. The acceptance results revealed no significant differences between both tilapia species in all three provinces. However, significant differences were found among the three provinces for the acceptance of the Nile and red tilapia fillets.

Fermented sausage is a favorite kind of meat-product that has allocated great proportions
of meat consumption in the world. For the first time in Iran in this study the production of
Fermented sausage from minced meat of common carp was assessed by means of lactic acid
bacteria at different incubating temperatures as 15, 25, and 35°C. To prepare the fish
sausage, common carp mince was grounded and mixed with NaCl (3%), glucose (3%) and
lactic acid bacteria at 5 log CFU/g and afterward were incubated for 48 h. During the
incubation of fish sausage, microbiological tests, moisture and protein content, and TVB-N
were measured. According to the results, the higher temperature of 35°C stimulated the
rapid growth of lactic acid bacteria, resulting in a rapid decline in pH, and consequently
suppressed the growth of pseudomonas, Micrococcaceae and Enterobacteriacea.

Microalgae as a source of valuable compounds such as fatty acids are isolated from the
natural environments and their mass production with high nutritional value is one the
necessities of many hatcheries. The present study aimed to determine the effects of enriched
daphnia with microscopic algae on some growth indices and survival rate of Persian sturgeon
(Acipenser persicus) larvae. Chlorella vulgaris and Scenedesmus dimorphus were purified
and cultured. Then, Daphnia longispina was fed microalgae including Chlorella vulgaris and
Scenedesmus dimorphus enriched with Docosahexaenoic acid (DHA). The microalgae density
to enrich daphnia was estimated at 5Ã 107 cells mL-1. Three treatments with three replicates
and a control group were considered in this study. A total of 30 Acipenser persicus larvae
were allocated to each sixty liters tank. Experimental fish were fed daphnia enriched with
Chlorella vulgaris (treatment 1), daphnia enriched with Scenedesmus dimorphus (treatment 2)
and daphnia enriched with Chlorella vulgaris and Scenedesmus dimorphus (at the rates of
50%) (treatment 3). Persian sturgeon larvae in the control group were fed like VNIRO stage
from daphnia caught in pond. Larvae were fed 30% of body weight per day for four times.
During the experimental period, water temperature, dissolved oxygen concentration and pH
ranged between 18-24°C, 5.8-7.2 mg l-1 and 5.6-8.2, respectively. The minimum (219 ± 98.4
mg) and maximum (315.16 ± 140.8 mg) mean (±SD) weights were observed in the control
group and treatment 3, respectively. The results obtained from the body weight increase (BWI
%) revealed that there were significant differences between treatment 3 and other treatments.
Highest (4.6±1.13% day-1) and lowest (5.5±1.24% day-1) mean (±SD) specific growth rates
(SGR) were recorded in fish fed the control group and treatment 3, respectively. Lowest
(68%) and highest (85%) survival rates were recorded in the control group and treatment 3,

In this study phytoplankton were used as a water quality index in agricultural sewage for
feasibility study of aquaculture in Ahwaz and Khorramshahr region. Monthly sampling was
done in 6 stations during one year period (2008-2009). 34 phytoplankton genuses were
identified. The most frequent classes were Bacillariophyceae (diatoms), Cyanophyceae,
Chlorophyceae, Dinophyceae. The water flow of drainage channel had inverse relationship
with phytoplankton density. Diatoms were present in all stations. Palmer index suggested that
station 2,5,6,3,4 had the highest rate of pollution respectively and station 1 was relatively
polluted. The stations of 1,2,5,3,6,4 had the highest value of useful phytoplankton index for
fish growth.

This research was carried out to study some physiological responses of mudskipper (i.e.,
Boleophthalmus dussumieri) as a biomarker Poly Aromatic Hydrocarbons (PAHs). Fish
specimens were obtained 5 stations (Arvand, Jafari, Zangi, Samayeli, Bahrakan) along north
western coast of the Persian Gulf (Khuzestan Coast). PAHs concentration was measured by
HPLC method. Lysosomal membrane change was measured by NRR time method and
stability of red blood cell membrane was evaluated by EOF test. Total PAH concentrations in
the sediments and the liver tissue ranged between 113.50-3384.34 ng g-1dw, 3.99-46.64ng g-1
dw, respectively. Highest PAHs pollution was found at Jafari while the lowest was detected at
Bahrakan, with significant between these 2 stations. Values of mean RT of the dye ranged
from 34 (for the blood samples of mudskipper collected from Jafari site) to 78 minutes (for
the blood samples of mudskipper collected from Bahrakan). Preliminary results showed a
significant difference among stations except between Arvand and Zangi. Osmotic fragility
curves indicated that erythrocytes collected from mudskippers at Jafari were the most fragile
followed by Zangi> Arvand> Samayeli> and Bahrakan. The results suggest that lysosomal
membrane change and red blood cell membrane stability in B. dussumieri could be extended
as a biomarker of oil pollution in marine biomonitoring programs.

Nudibranches are the largest group of Hetrerobranches, (a sub-branch of Opisthobranchia)
and are widespread and cosmopolitan species. They vary in shape and colors and occur in all
waters from intertidal to deep sea zones and from polar to the tropics regions. Nudibranches
are subdivided in two main groups including Anthobranchia and Cladobranchia. In the present
study, based on morphology the svudied species was identified as Goniobranchus annulatus
that belong to Anthrobranchia group. In molecular analysis the sequences of the partial
mitochondrial COI gene of Goniobranchus annulatus species from Iran with 15 similar
sequence of nudibrnaches from genbank were compared. Phylogenetic based on
Neighbor_joining analyze showed a monophyly relationships between families of
nudibranches and also revealed that Goniobranchus vibratus is a sister taxa to the
Gonidbranchus annulatus from Iran Goniobranchus annulatus with 100% bootstrap support.

In this study, the effect of Rosemary and Zataria extracts on three different treatments in frozen
Silver carp minced were studied in normal packaging. Therefore, a control and three treatments were
defined:
Treatment 1 - Control: frozen meat packaged in conventional
Treatment 2: Frozen Silver carp minced + Zataria 300mg/kg in normal packaging
Treatment 3: Frozen Silver carp minced + Rosemary 200mg/kg in normal packaging
Treatment 4: Frozen Silver carp minced + Rosemary compound (100mg/kg) and Zataria (100mg/kg)
in normal packaging
After quick freezing of samples in the spiral freezer by individual quick freezing method, to maintain
the cold temperature (-18)°C were transferred. For six month, Sampling and measurements to
determine the fatty acid profile of the zero phase beginning in the first month and then every ten days,
and 15 days in the second month of the third month after the monthly test. Identifying, defining and
measuring the fatty acid profile by gas chromatography was performed. In this study, levels of both
saturated and unsaturated fatty acids in three experimental and one control were identified as follows:
A: SFA: (Saturated Fatty Acid): Meristic C14: 0/ Palmitic C16: 0 /Hepta decaenoic C17: 0 / Stearic
C18: 0 / Arashidic C20: 0
B: (MUFA Mono Unsaturated Fatty Acid): Palmitoleic C16: 1-W7 / Oleic C18: 1-W9 /Gadoleic C20:
1 - W9
C: (PUFA Poly Unsaturated Fatty Acid): Linoleic C18: 2-W6 /α-Linolenic C18:3-W3
D: (HUFA High Unsaturated Fatty Acid): Arachidonic C20: 4 - W6 Eicosa panta enoic acid C20: 5-
EPA/W3 Docosa hexa enoic acid C22: 6-DHA/W3. Results of this study was to determine keep frozen
fish meat containing extracts of Zataria and Rosemary in freezing conditions, stability of different
types of fatty acids, mono unsaturated fatty acids, poly unsaturated fatty acids, high unsaturated fatty
acids, So that none of the fatty acids measured, were not observed increase or decrease Changes over
time while maintaining the oxidation of fatty acids is minimized.
The results obtained from the profile of fatty acids and their related indices and statistical tests
show the treatment contains Rosemary extract show greater stability than thyme during storage (-
18)°C. According to studies, Frozen minced fish meat treated with extracts of Rosemary, was used

The aim of the present study was to determine the impact of replacing the fish oil by
alternative lipid sources in diets for rainbow trout (Oncorhynchus mykiss) on growth, fatty
acid profiles of muscle. Five isonitrogenous and isoenergetic semipurified diets were
formulated containing 100% rice bran oil (RBO), 100% linseed oil (LO), 100% Soybean oil
(SO) and a 1:1:1:1 rice bran, linseed, soybeen and fish oil mixture (MX) were compared to a
pure fish oil (FO) diet. The diets were fed to apparent satiation twice a day to triplicate groups
of 30 rainbow trout with an initial weight of 90g for 15 weeks at 12°C.At the end of the
experiment, fillet samples were collected from fish for the measurement of fatty acid profile
and fillet composition. Fish fed the FO diet had the highest weight gain over the experimental
period (280.28 g), However no differences in growth rate and CF were observed across diet
groups. Feed conversion ratios (FCR) ranged from 1.12 to 1.24. Significant difference in
FCR was found in the group fed an FO diet. The fillet lipid concentrations and fatty acid
composition of the fish were significantly affected by the experimental diets. Fish fed the FO
diet contained significantly lower lipid levels (20.18%) than those fed the 4 other diets. The
highest level of n-3 PUFA concentrations were recorded in fish fed the LO diet (21.8) with
significant difference than other diets and the lowest were in those fed the RBO diet (7.84).
Fish fed the SO diet contained significantly higher level of n-6 PUFA concentrations (31.72)
than other diets and the lowest were in those fed the FO diet (19.15). Fish on the FO diet had
a significantly greater percentage of DHA (10.10%) in muscle tissue compared with fish on
all other diets and the lowest was in those fed the RBO diet (2.81%). However, the highest
level of eicosapentaenoic acid (EPA) concentrations was recorded in fish fed the SO diet
(1.84%) and the lowest in those fed the diet (0.67%). This study showed considerable
reductions (about 3-fold) in the n-3/n-6 ratio when FO in the fish diet was replaced by rice
bran and soybean oils, which may be extremely negative from a nutritional point of view. In
other hand linseed oil had the highest n-3/n-6 ratio (0.91) that was comparable with fish oil n-
3/n-6 ratio (0.89). The results in this study imply that an appropriate mix of vegetable oils and
FO can replace the sole use of FO in fish feeds.

In the present study, accumulation of manganese, cadmium, zinc, iron and copper in the
commercially fish species (silver pomfret and tiger tooth croaker) caught from Bandarabbas
coasts at 2010 was measured and the risk of daily intake of them in Hormozagan urban
population was estimated. The average concentrations (μ/g dry weight) of manganese,
cadmium, zinc, iron, and copper in the muscle tissue of silver pomfret were 1.248, 0.217,
14.444, 2.397 and 3.300, respectively, while the concentration of them in tiger tooth croaker
were 1.009, 0.403, 12.564, 4.467 and 2.366, respectively. According to fish consumption rate,
urban populations of the province were divided into four groups low, medium, high and very
high. The target hazard quotient (THQ) in each group calculated separately. The THQ of all
groups were much lower than 1 in the two fish. The results showed that urban populations of
the province have not any risk due to accumulation of the studied heavy metals.

per
Diplostomum spathaceum is a digenean parasite with an indirect life cycle. Its mature stage
lives in gull's intestine, cercariae in snails (Lymnaeidae) liver and metacercariae stage in
piscine, amphibian, and mammalian eyes. Notice that penetration of cercariae into skin and
eye cause lesions which cause susceptibility to secondary infections, appetite loss due to
infections, blurry vision, and disability in hunting and feeding on fish. It, therefore, plays an
important role in aquatic health. During this study, prevalence of Diplostomum spathaceum
infectious in 240 introduced and endemic fishes of water resources in West Azerbaijan
province were studied from spring 2008 to winter 2010. The results indicate that 58/30 % of
fish (140 fish) showed infestation with this parasite which presents a high rate of infestation in
the fishes in these water resources.
