    Description: The gobies exhibit a main role in the general production of the Caspian Sea due to their species diversity and unexploited stocks. So, of the 80 fish species known from Iranian part of the Caspian Sea, 10 of them are gobies. The deepwater goby, Ponticola bathybius (Kessler, 1877), Gobiidae, is a native species in the Caspian Sea which settles on sandy and shelly substrates and, in a few numbers, on firm silt down to 75 meters. The presence of predators such as Acipenseridae and prey items as Clupeonella sp. could be effective in the abundance of gobies. Gobies fishes are known as the great consumers of food resources and the considerable competitors for other species. ... In Iranian coastal waters of the Caspian Sea, there are differences in some important ecological factors including substrate type, slope and light intensity which may affect the prey community. Therefore, this study was carried out to compare dietary composition of P. bathybius at three different localities (Bandar-e-Anzali, Salmanshahr and Miankaleh) along the southern Caspian Sea coastal waters.

    Description: Anzali Wetland as a listed habitat in Montreux Record, was investigated for the mammal fauna during Jan. 2015 - Jan. 2016. About 165 km of water bodies and 200 km around Anzali Wetland were patrolled, respectively. By applying different methods, such as direct observation, different signs recording, using different sampling traps,nets and camera traps, twenty mammal species were identified from 5 orders and 13 families. While Wild boar,Golden Jackal and Common otter were widely distributed, Common badger, Asiatic wildcat and Jungle cat were observed in some parts of this wetland. Six rodent species were recognized in different parts of the wetland. Among four identified bat species, Nathusius’s pipistrelle has been reported only from this region in Iran. The most commonly recorded bat species was the Soprano pipistrelle, a species hereto recorded only from two Iranian localities. Two recognized species from order Eulipotyphla; Caspian shrew and a mysterious mole are important due to their narrow geographical distribution range as well as their taxonomic situation. Although there was no quantitative or qualitative data from the past, our results show that the situation of many mammal species are not suitable, and some of them are being increasingly threatened.

So, of the 80 fish species known from Iranian part of the Caspian Sea, 10 of them are gobies (Abdoli et al., 2012). The deepwater goby, Ponticola bathybius (Kessler, 1877), Gobiidae, is a native species in the Caspian Sea which settles on sandy and shelly substrates and, in a few numbers, on firm silt down to 75 meters (Miller, 2003). The presence of predators such as Acipenseridae and prey items as Clupeonella sp. could be effective in the abundance of gobies (Kalantarian et al., 2013). Gobies fishes are known as the great consumers of food resources and the considerable competitors for other species (Corkum et al., 2004). According to Miller (2003), fish are as dominant prey for larger specimens of P.
