ABSTRACT
Introduction: Meat, fish and other livestock to various reasons that are consumed orally
is preferred. Given the importance of the health of fish to be used in human society
seems essential. Gill necrosis syndrome is one of the most important diseases in the
aquaculture industry. The purpose of this study was to investigate the prevalence of
histopathological gill necrosis in carp carrot opioid Lake is distracted. Methods: In this
study, 100 pieces of carp (carrots) Kazeroon distracted Lake fishing and ice
compartments Rubber powder was sent to the lab. Fish Pathology Laboratory, Faculty
of Veterinary Medicine, the measure biometric characteristics such as weight, length
and ... And clinical studies , necropsy was attempted and the observations recorded , the
fish gills were isolated and transferred to 10% formalin solution. The gill tissue sections
were stained with hematoxylin and eosin, they were studied. Results: In 31 % of cases,
one or microscopic signs were observed in 69 % of cases, no symptoms were reported
pathology. The most important microscopic signs, including the collapse of the
cytoplasm membrane 28, 23 hypertonic cytoplasm, nucleus Hypertrophy 25, 17 pick

INTRODUCTION
Rapid population growth and decline in world fish stocks for several reasons, including water pollution,
environmental degradation and ... Has led to a more pressing need to maintain the health of the animal species to
be felt. Furthermore, the use of different reasons other livestock, meat; fish that are consumed orally is
preferred. Given the importance of the health of fish to be used in human society seems to be very important [6].
Carrots belong to the ruler of fish fauna, branches Owners ropes, Category orders Shaklan fish carp family
Cyprinidae, the family carp, C.carpio and scientific names of species Cyprinus carpio [5].
This species of fish has an elongated body, head down and pressed flat, greenish -white body color, no
Palpus and fin is short [6].
There are five pairs of gill arch. In front, four pairs of primary gill cylindrical blade, to create two rows
from the front to the back extends. The two rows at the base by gill walls are connected to each other. The
radius on the front edge of the gill arch is located are inclined upward. Usually the last couple pharyngeal gill
arch bone is altered role in breathing fish [1]. Chilodonella or two nellyisms pounds, skin and gill parasites of
freshwater and brackish disease are caused by the chilodoneloze. chilodonella genus belonging to the family
chilodonella , critoforyde dark, cynto frogmino phore class A, and is a branch of ciliates [5].
eyctiofibrious multi phylious external parasites most dangerous fish is freshwater white spot disease ,
eyctofetirious are created. The disease can cause severe losses in fish. In marine fish, there is a similar parasite
that is crypto carrion airtians [4].
The tissue fluids and particles are resulted from the destruction of the parasite feeds. The lining is thin at
first but gradually begins to thicken and becomes hyperplasia [4].

A lierne has hard skin parasites that can cause severe freshwater fish and occasionally sea. Because of their
specific shape that is also known as hookworm. A lierne genus belongs to the family lierne. And has more than
40 species lierne species of this genus is most species. Create a boil -like lesions on the scalp, trunk, fins and
gills are. In severe infections may be worn across the body of the fish small and large wounds and mucous thick
cover on the scales [7].
Cryptobia sex is the most common protozoan flagellate parasite. Several species of this genus cause
disease, pollution and economic cryptobiosies freshwater and saltwater fish are the world [4].
Infection by bronchioles Cryptobia red gills, but has abnormal mucus accumulates abundant in gills and
skin [3]. Gyrodoctylous the most important parasites of parasites in a single host ( Monogenous ) which is about
0.5 mm in length and the color is white [4] . This parasite is rarely seen with the naked eye and usually the skin
and rarely fish gills and eyes will be present. Columnaris disease, a disease of the skin and gills of freshwater
fish by Flexi Columnaris is caused by bacteria [2]. These bacteria will multiply at high temperatures.
Considering the above mentioned issues and the importance of feeding the fish in the present study was aimed
to investigate the prevalence of histopathological gill necrosis in carp Carrot Lake is distracted Kazeroon
Methods:
The study was done on rainbow trout farm, trout Arjan plain located in Fars province.
Rainbow trout was listed weight.
After obtaining samples from salmon farms Arjan, in boxes containing rubber powder and put ice to our
laboratory were transferred ichthyology of Veterinary Medicine, Islamic Azad University of opioid. In the
laboratory, biometric characteristics such as weight, length, and other symptoms were reviewed and data. Then
by the dissection instruments, including forceps, scissors, scalpel, Sean, pin and ... Autopsies were performed.
After recording the above information and pictures of the steps listed to laboratory histopathology of Veterinary
Medicine was transferred tissue blocks with dimensions cm 1 × cm 1 from fish liver rainbow trout catches taken
and formalin (10%) previously prepared was transferred . Then, for each sample, two slides, each slide contains
two sections of tissue, tissue was prepared. The histological evaluation was performed by light microscopy.
Results:
The main histopathological findings observed in various stages of necrosis of gill tissue necrosis which can
vary depending on factors causing disease. In the present study it was found that this effect was shown in 31 and
69 cases had not seen a sign of the syndrome. The most important microscopic signs, including the collapse of
the cytoplasmic membrane 28, 23 hypertonic cytoplasm, nucleus Hypertrophy 25, 17 pick nose, 11 are replaced
by connective tissue (Fig. 1) (Fig. 1 to 6).

Discussion and conclusions:
Fish carp gill necrosis factor, bacterial, fungal, viral, parasitic, and terrain factors, toxicology, nutritional
factors and complications of neoplastic disease is caused. In this study on 100 carp pond were Fars distracted
opioid city, 200 slides were prepared. After investigation it was found that samples most carps the fish pond,
with gill necrosis are common.
Previously stated that gill necrosis (Fin Rot) in the southern Baltic Sea fish trusulus metlyous odious tumor
necrosis factor-alpha in amoebic gill necrosis is the main role in causing disease [8] .5 micron diameter
increases, more hypoxic effects can be observed in fishes . Gill necrosis and bacterial agents who in relation
caused by environmental stress are created in three steps:
1 – Gill Influenced by environmental stress such as ammonia, acidity and toxins yellow or dark purple

It comes as no traces of the bacteria were seen at this stage.
2 - During this stage the bacteria attack and cause damage to the gills, gill necrosis, so that a layer on the
gill covers, white and gray.
3- Washing by freshwater amoeba positive effect on removing the gills of fish amoebic gill disease (AGP)
is. However, re-infection can occur again within a week [9,10].
Sodium- hydrogen exchange system in cell- stone carpet is done. The most sensitive organs of bony fish
gills are extremely vulnerable because external position and in direct contact with water and trigger water or
suspended in water and are hurt. Reported epidemic in America Pennsylvania led to 90 % mortality of carp fish
in the area. Chronic infections, especially parasitic disease may be a large number of inflammatory cells in the
gill filaments (lymphocytes - macrophages) are present. Lamella chronic glaucomatous disease may spread like
a bacterial disease that affects the kidneys [11,12,13].
It also stated that the edema and hypertrophy of gill epithelial cells in acidification of water and increasing
water pollution by aluminum can be seen. Significant associations between blood ammonia and ammonium
levels carp gill necrosis, a disease of the blood of carp ever increasing concentration of more than 5/3 is
equivalent to milligrams per liter. That the main cause of death in Ireland, viruses Spring carp fish carp (SVC)
[14,15].
Conclusions:
In general at the end of pathology we can say that the syndrome named gill necrosis in fact is a complex of
different defects of gill and its diversity is on the basis of frame changes and symptoms of illness. Gill syndrome
is result of primary and secondary factors which spread among the primary causes of ammonia and PH to stress
and physical and chemical parameters and infection can also have devastating effects on the epithelial cells of
the gills.
