Four feeding levels (40%, 60%, 80% and 100% of satiation) were designed as the different treatment groups to assess its effects on water quality and plankton community structure in the yellow catfish rearing enclosure ecosystem. The results showed that the weight gain and specific growth rate decreased significantly as the feeding level decreased. The soluble nutrients (except for NO2-N) concen...

Recent work suggests that mammalian retinal ganglion cells may become more like developing ganglion cells in form while regenerating through a peripheral nerve graft. We have injected Lucifer Yellow into regenerating ganglion cells of goldfish to look for similar changes. Within three weeks of injury, we saw dye-coupling to nearby cells, which is a common developmental feature in many species. ...

OBJECTIVE To compare the sensitivity and specificity of fluorescence in situ hybridization (FISH) with real time polymerase chain reaction (RT-PCR) in the diagnosis of Chronic Myeloid Leukemia (CML). STUDY DESIGN A cross-sectional, analytical study. PLACE AND DURATION OF STUDY Haematology Department, Armed Forces Institute of Pathology, Rawalpindi, from January 2012 to February 2014. METH...

The functional, nutritional, and antioxidative properties of hydrolyzed herring and herring byproducts (head and gonad) were evaluated. All freeze-dried herring fish protein hydrolysate (FPH) powders were light yellow and contained 77% to 87% protein. The degree of hydrolysis was 18.3%, 13%, 13%, and 10.1%, respectively, for head, whole fish, body, and gonad after 75 min digestion. All FPH powd...

Mosquitofish (Gambusia affinis) is an example of a freshwater fish species whose remarkable diffusion outside its native range has led to it being placed on the list of the world's hundred worst invasive alien species (International Union for Conservation of Nature). Here, we investigate mosquitofish shoaling tendency using a dichotomous choice test in which computer-animated images of their co...

The parameter value of ornamental fish is determined by the brighter color a type fish, higher so that farmers need to maintain providing feed containing pigments can be obtained from vegetable and animal sources carotenoids. Sunkist balloon molly (Poecilia sp.) were stocked in an aquarium measuring 60 × 30 cm3 (5 fish/l), Objectives this study was determine effect feeding formulations using di...

Background: The traditional power law model, W(L) = aL, is widely applied to describe weight (W) vs. length (L) in fish. The exponent, b, is independent of the system of units and has an easily interpreted physical meaning as related to isometric growth (b = 3). In contrast, the coefficient, a, depends strongly on both the exponent and the system of units, and its physical meaning is difficult ...

BACKGROUND Understanding different patterns of fish consumption is an important component for risk assessment of contaminants in fish. A few studies on food consumption had been conducted in Malaysia, but none of them focused specifically on fish consumption. The objectives of this study were to document the meal pattern among three major ethnics in Malaysia with respect to fish/seafood consump...

Concentrations of total aluminium (Al) and iron (Fe) were determined in Lake Loskop over a period of four months in 2009 in samples of phytobenthos, phytoplankton, macroinvertebrates, amphibians and fish. The highest concentrations of Al and Fe were measured in the filamentous algae Spirogyra fluviatilis (Hillse) and Spirogyra adanata (Kütz), (Al=18,997.5mgkg(-1) dry weight and Fe=22,054.2mgkg(...
