Background: The fishes of family Gobiidae are one of the least studied fishes, especially for otolith structure. The otoliths were possess species specific features. Hence, traits of sagittal otolith of gobid species studied. Methods: Five gobid species Odontamblyopus roseus (Valenciennes, 1837), Trypauchen vagina (Bloch and Schneider, 1801), Glossogobius giuris (Hamilton, 1822), Parachaeturichthys polynema (Bleeker, 1853) and Boleophthalmus dussumieri (Valenciennes, 1837) were investigated by three methods including morphological, shape indices and step wise discriminant function analysis (SDFA). Result: Interrelationship between shape indices investigated, at 95% level of confidence (P less than 0.05), revealed that perimeter of P. polynema and area of T. vagina have isometric growth with their length (b = 3.0071, 2.90, respectively) and otolith area of B. dussumieri have positive allometric growth (b = 4.23077). SDFA, based on otolith morphometry, discriminated species up with 97.18% accuracy. Hence, the results of present investigation can be used for discrimination of the species and as a tool in predicting fish size from the otoliths and in calculating the biomass of these less studied fish species.

An investigation was carried out to compare the physical, chemical, microbiological and sensory properties of three freshwater dried fish products of Wallago attu Bloch & Schneider, 1801 (Siluriformes: Siluridae), Channa striatus (Bloch, 1793) (Perciformes: Channidae) and Glossogobius giuris (F. Hamilton, 1822) (Perciformes: Gobiidae). The traditionally sun dried fishes were collected from Kawran Bazar Fish Market, Dhaka, Bangladesh. Results showed that the water reconstitution properties varied among the dried fishes where maximum rehydration was observed in the C. striatus at room temperature, 40 oC and 60 oC. Moisture content of W. attu, C. striatus and G. giuris were 22.70% +/- 0.45%, 18.75% +/- 0.58% and 21.93% +/- 0.54%, respectively; the protein content were 61.85% +/- 0.99%, 66.44% +/- 1.02% and 62.83% +/- 0.87%, respectively; the lipid content were 6.21% +/- 0.93%, 6.81% +/- 0.72% and 5.98% +/- 0.55%, respectively, and the ash content were 6.79% +/- 1.11%, 6.49% +/- 1.29% and 7.83% +/- 0.98%, respectively. Peroxide value, acid value, pH, TVB N value and aerobic plate count were found to be highest in W. attu followed by G. giuris and C. striatus. Results of this study revealed that traditionally sun dried fish products were acceptable quality in terms of physico-chemical, microbiological and sensory aspects.

AbstractCharacteristic features of histology and fine morphology of the olfactory organ in the tank goby, Glossogobius giuris (Perciformes, Gobiidae, Gobiinae), were investigated with light and scanning electron microscopy. The olfactory cavity contained single lamellae that were exposed to the aquatic environment by small anterior and posterior nostrils. Typical olfactory rosettes were not observed. Histologically, each lamella consisted of two layers of epithelium; wrapping the central core that was composed of connective tissue stroma with nerve fibers and blood capillaries. The mucosal lining of lamella was merged with sensory and non-sensory olfactory cells, identified on the basis of structural characters, surface specializations, and staining features. The principal sensory elements were ciliated receptor cells that were characterized by apical dendritic processes expanded from cell soma and microvillous receptor cells equipped with multiple tiny dendrons on the mucosal surface. The bead-like appearance of several labyrinth cells, mucous cells with secreted mucin, scattered lymphatic cells, stratified epithelial cells bearing microfolds, and condensed ciliated supporting cells were observed in the non-sensory epithelia. Undifferentiated basal cells were embedded in the deeper zone of the epithelium above the basement membrane. The cellular organization of the olfactory lining was interpreted with chemoreception of the fish concerned.

Muara Gembong Beach is part of the eastern area of Jakarta Bay which is still a source of fish consumption for the local community. This study aims to present information about the concentration of metals in several types of fish. The study was conducted in October 2018 at 5 stations, namely the Citarum River, Muara Bendera, Pulau Buaya, Muara Blacan, and Muara Jaya. The parameters measured were copper (Cu), cadmium (Cd), Chromium (Cr), lead (Pb), Zinc (Zn), mercury (Hg), and Arsen (As) in several types of fish consumption sizes, with the local names Kuro (Eleutheronema tetradactylum), Keropak (Hexanematichthys sagor), Bloso (Glossogobius giuris), Samgeh (Nibea soldado), Shrimp (Macrobrachium rosenbergii), Mujair (Oreochromis mossambicus), Patin (Pangasianodon hypophthalmus), and detected in fish samples. Zn was detected in all fish samples and research stations, while Cu was detected in shrimp in Muara Blacan and Muara Flag. As detected in Kuro in Muara Jaya, Mujair in Muara Blacan, Shrimp in Muara Bendera. The concentration of Zn, As, and Cu has exceeded the quality standard in biota. Prevention of the entry of waste containing metals into waters, among others, through increasing public regulations and strict sanctions from the government.

An experiment was conducted in the laboratory of the Department of Agricultural Chemistry, Bangladesh Agricultural University (BAU), Mymensingh to determine protein and major mineral nutrients (viz. Ca, Mg, Na, K, P, S and Fe) in different available fish species of the Brahmaputra River of Bangladesh. Total 32 fish samples of 15 fish species were collected from three locations of the river during November 2017. The highest amount of Ca (2.00%), Mg (4.17%), Na (0.41%), K (3.24%), P (0.17%), S (0.129%) and Fe (226.9 mg kg−1) were obtained from chela (Salmophasia bacaila), chanda (Chanda nama), chingri (Macrobrachium sp.), shingi (Heteropneustes fossilis), bele (Glossogobius giuris), baim (Macrognathus aculeatus) and mola (Amblypharyngodon mola), respectively and the sequence of the mineral nutrients was K > Mg > Ca > Na > P > S > Fe. The study results revealed that 100% of daily Ca requirement can be replenished by consuming 100 g fish flesh portion of the chela (Salmophasia bacaila)/ chingri (Macrobrachium sp.)/ bele (Glossogobius giuris). Similarly, among the 15 fish species, 11 and 12 species alone can contribute 100% of Mg and K requirement for human by taking 100 g fish flesh, respectively. The maximum content of N (3.88%) was obtained from shingi (Heteropneustes fossilis), while the minimum (2.81%) was recorded from mola (Amblypharyngodon mola). The protein content among the fish samples varied between 17.6-24.3% with a mean value of 21.2%. Finally, the study results concluded that the common fishes available in the Brahmaputra River are a good source of protein and major mineral nutrients, which contributes in nutrition to the local people of the country.

Glossogobius giuris were collected during March to September 2013 from the Payra river to estimate the length-weight relationship with relative condition factor (Kn), fecundity, gonadosomatic index (GSI) and relation between fecundity and other parameters. The length-weight relationship was found to be Log W= 2.667 Log TL – 1.805 in male and Log W = 2.931 Log TL – 2.040 in female. The mean Kn were found to be 1.02±0.155 for male and 0.97±0.276 for female which indicates satisfactory condition of the fish population. The mean relative fecundity was ranged from 88495 to 264104 with a mean value of 171581±17855, having a average total length of 21.21±0.44 cm, body weight 70.22±4.62 g and gonad weight 2.74±0.31 g. The relationships among the fecundity, the total length, body weight, gonad weight were found to be linear and positively correlated. The mean GSI value was 3.42±0.33 and the highest GSI value was recorded 9.34±0.71 in the month of September. This study will help to introduce this species in sustainable aquaculture through proper management and for the development of induced breeding technique.
