Myxozoan spores were observed in yellowfin goby Acanthogobius flavimanus collected from Suisun Marsh, San Francisco Estuary (SFE). Although histopathological changes associated with the parasite were not observed, the spores formed plasmodia that partially blocked the gastric and intestinal mucosa and gut lumen and may affect the perfomance and survival of the yellowfin goby. Morphological feat...

The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990).  Analysis of fatty acid methyl e...

The distribution and dynamics of microcystins in various organs of the phytoplanktivorous bighead carp were studied monthly in Lake Taihu, which is dominated by toxic cyanobacteria. There was a good agreement between LC-MS and HPLC-UV determinations. Average recoveries of spiked fish samples were 63% for MC-RR and 71% for MC-LR. The highest MC contents in intestine, liver, kidney and spleen wer...

Effect of sodium alginate coating enriched with horsemint essential oil (HEO) on the quality of bighead carp (Aristichthys nobilis) fillets at refrigeration temperature (4 ± 1°C) was studied. Bighead carp fillets were coated with neat sodium alginate (SA) and sodium alginate containing 0.5 and 1% v/v of HEO and their quality changes in terms of total volatile basic nitrogen (TVB-N), peroxide va...

Traditionally, water quality guidelines/criteria are based on lethality tests where results are expressed as a function of waterborne concentrations (e.g. LC50). However, there is growing interest in the use of uptake and binding relationships, such as biotic ligand models (BLM), and in bioaccumulation parameters, such as critical body residue values (e.g. CBR50), to predict metal toxicity in a...

In order to clarify the mechanisms of neoteny in the ice goby ( Leucopsarion petersii ), we examined effects of thyroid hormone and thiourea (TU) treatments on their neotenic characteristics and the pituitary-thyroid axis. Adult ice goby were exposed to 3, 5, 3’-triiodothyronine (T3, 0.1 ppm), TU (inhibitor of thyroid hormone synthesis, 30 ppm), or the combination of the two for 2 weeks. Observ...

The aim of this study was to determine the influence of environmental parameters onthe abundance of monkey goby Neogobius pallasi. A total of 526 and 163 individuals ofmonkey goby specimens were caught by electro-shocker in the Kaboodval and Shirabad Streams, respectively. The ranges of total length of the specimens in Kaboodval and Shirabad Streams were respectively 22-137.55 mm and 32.64-137....

In nature, the Goby fish lives in symbiosis with the burrowing shrimp; serving as a watchman in return for a place to live. Current adaptive learning systems hold an ambiguous position that attempts to compensate for real-world interaction. This paper presents a novel symbiotic-dialog approach to abstract cognitive skill training. The approach is implemented within Goby, a third-party symbiotic...

Concentration and electrophoretic properties of blood serum albumin of the round goby Neogobius melanostomus caught in Black Sea and Azov Sea were studied in relation to age, sex, maturation stage and season. Electrophoretic mobility of serum albumin in Black Sea fish increased with age, while in Azov Sea goby it varied less. No differences were observed in albumin characteristics between femal...
