  • Histological, morphological and physiological studie on the ontogenic development of digestive tract in Alburnus chalcoides

    Zakeri-nasab, Masrour (Islamic Azad University, Science and Research Branch, Tehran, 2018)
    Alburnus chalcoides is a member of the Cyprinidae, which is considered as biologically, ecologically and economically important fish. Sampling of this fish was done randomly from the first day after hatching to pre-puberty at different intervals. The growth of this fish was investigated morphologically and histologically by Hematoxylin-Eosin staining method, and the secretion of gastrointestinal mucosal layers of the cells from carbohydrates was studied by histochemical analysis by periodic acid scavenging. To study the physiology of fish, its digestive enzymes were studied. Anatomical study on this fish showed that its digestive system consists of two major parts of the esophagus and intestines. In the early days of the digestive tract, it was a simple and simple tube in which mucosal secretions were not observed, but after the appearance of the Goblet cells, this activity began and a layer of neutral polysaccharide compounds was observed on the gastrointestinal tract. The presence of neutral polyunsaccharide secretions in the gastrointestinal mucosa has shown that it plays a role in the digestion and absorption of food and is important in protecting the epithelial layer of the digestive tract and passing food. In enzymatic studies, it was found that all enzymes had a significant difference in the level (p <0.05). The trypsin, chymotrypsin, and amino-peptidase enzymes have been shown to be more prominent in the two active start-ups, and the third and fourth weeks (entering the infant's age and adolescence). The alkaline phosphatase enzyme has a relatively stable trend and increased on the fifth day (mouth opening) and decreased slightly from week 4. Lipase and amylase also have a decrease trend, which is likely to be linked to a high protein diet of the animal. The start of active nutrition was increased, evolutionary characteristics of this fish were somewhat similar to other fish of the carp species, but there were also some differences.

    In this study, the identification of the Acanthopagrus species Sparidae family by morphometric characters & meristic counts and the stock separation of Arabian yellowfin Seabream Acanthopagrus arabicus as the dominant species was determined through geometric morphometric and otolith shape in the west and east part of the Hormuz Strait. Samples were collected in five different areas including Khuzestan, Bushehr and Hormuzgan Waters as the west of Hormuz Strait, and Jask, Sirik and Sistan & Baluchistan Waters as the east of Hormuz Strait from June 2014 to May 2016. A. arabicus, A. berda and A.bifasciatus were identified in the northern part of the Persian Gulf & Oman Sea, the first one was identified as a dominant species of this genus. Evaluation of morphometric characters and meristic counts indicated that individuals of A. arabicus in west and east of Strait of Hormuz were significantly different from each other which showed high phenotype diversity of this species (p<0.05) and 85.3% of the individuals were categorized precisely in the correct classification which indicated as a key identification method in the region. From the meristic counts, the number of scales on the lateral line, on the chin and scales from the fifth and ninth spine of dorsal fin to the lateral line were the factors of separation in the west and east of the Strait of Hormuz. Body shape analysis was showed the most variations on the head and top of the body and significant differences of body shape was proved between west and east of Strait of Hormuz. Landmark positions in the samples of the west Strait of Hormuz were indicated the decrease of body depth, increase of head length, leaning of base and pectoral and ventral fin to upper part of the body, meanwhile it was contrary in the samples of the east. CVA correlation analysis showed a significant difference in body shape in the west and east of the Strait of Hormuz (P <0.0001). The otolith shape indices showed a significant difference in the west and east of the Strait of Hormuz and the results of the DFA analysis confirmed the accuracy of the classification of the species in the main region by 53.8 percent and the otolith shape in the west of the Hormuz Strait was more circular and had an equal growth in the length and width, while in the eastern part of the Strait of Hormuz they had more growth and aspect ratio, ellipticity and form factor of the area were approved. The results of the otolith Fourier Shape Analysis showed that six components out of the 77 main components were expressed 90 percent of the cumulative strength and difference, and the most changes were observed in the dorsal and ventral part of the otoliths of the Arabian yellowfin Seabream, and 70.4% of individuals of this species were correctly classified in the west and east of the Strait of Hormuz. The results of this survey confirmed two separate stocks in the west and east of Strait of Hormuz.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran UniversityIran, 2017-06)
    Colletteichthys dussumieri or Batrachus dussumieri or Austrobatrachus dussumieri as flat toadfish is a sedentary and solitary species that lives partly buried in soft sand and mud or concealed in rock crevices, in coral reefs or in sea grass or weedy bottoms and in tidal pools, where they function as ambush predators feeding. They prefer high saline waters and also experts in camouflage therefore flat toadfish lives in the demersal, marine environment. Size of C. dussumieri is 14 cm in Iranian Waters of Persian Gulf (Kish Island). Their ability to change color to lighter or darker shades at will and their mottled pattern makes them difficult to see Toadfishes are said to be quiet vicious and will snap at almost anything upon the slightest provocation. Toadfishes do not school, but they are gregarious and tend to congregate together. They have limited dispersal ability because of their demersal eggs which lack pelagic larvae. Compared to other fishes, they are sluggish in nature. This species is dimorphism and spawning only once in a year. Toadfish are well known for their ability to "sing", males in particular using the swim bladder as a sound-production device used to attract mates. Food: Colletteichthys dussumieri is feeding fish, prow, crab, isopod, squilla and mullasca.

    Plectorhinchus gaterinus or Blackspotted rubberlip known as Grunts, Black-spotted Grunt, Blackspotted wweetlips, Spotted grunt, Spotted sweetlips. P. gaterinus is reef-associated and may also occur in sand banks and near estuaries. The Blackspotted rubberlip occurs in coral and rocky areas, inhabiting depths between 3 m and 55 m. It found singly or in large groups in coastal waters and reef flats often sheltering during the day under ledges. In some areas sweetlips are known as "Grunts" because they "grunt", the grunting sound is produced by their flat teeth plates rubbing together and this is amplified by their air bladders. Sweetlips can be distinguished from other species by their very large rubbery lips. P. gaterinus commonly reaches a length of 30 cm, with a maximum size of 50 cm in males. Body of the adults is silvery with black spots and yellow lips and fins. The forehead of the head is gray. This species is oviparous with distinct pairing during breeding. Small juveniles show longitudinal black stripes.

    Lutjanus ehrenbergii is known as Blackspot snapper and Black-spot snapper. L. ehrenbergii is widely distributed in the Indo-West Pacific at depths ranging from 5 to 20 m. This reef-associated species inhabits very shallow coastal habitats, often in large schools near freshwater run-offs. Adults inhabit coral reefs, while juveniles frequent inshore areas over sand, silt or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries. This species may enter freshwater areas to consume small fish and invertebrates. This species reaches sexual maturity at approximately 2 years of age and reaches a maximum age of at least 11 years. Growth trajectories are significantly different between sexes for L. ehrenbergii with females achieving a larger asymptotic size than males. This species is a component of fisheries to varying degrees throughout its range. It is highly sought after in some areas, such as the Persian Gulf, and is commonly seen in subsistence fisheries and markets through other parts of its range.

C. novaeguineae is living coral reefs at reef edge and slope at depths of 1 to 20 m. We report for the first time from Bali Waters (Indonesia). This species has exhibited a slight preference for the coral Acropora spp. over Poccilopora spp. and Porities spp. A mature C. novaeguineae is pentagonal in shape with an inflated appearance and much-abbreviated arms. It can grow to a diameter of 30 cm. Rows of tube feet are on the underside, and it has a central mouth. The color is very variable and includes a mottling with darker and lighter shades of fawn, brown, orange, yellow and green. The armored body wall is made of calcareous ossicles which are supported internally by pillars which buttress the ambulacra. The armouring contains pits into which the tube feet can be retracted. The body cavity is filled with water. Small cushion stars are very different in appearance. They are star-shaped, with five short, broad arms and a low profile. As they grow, the inter-arm areas fill in and expand relative to the tube-feet areas, and the arms get shorter relative to the disc which becomes inflated and more massive.
