there are various factors affecting the fighting fish larval survival including nutrition, substrate, water quality, pathogen and stress. experiments were conducted to study the effect of substrate and live feed on larval survival of fighting fish fry. nine small glass aquaria (60 cm × 30 cm × 30 cm) were used as breeding tanks. equal pieces (80 cm2) of rigifoam (t1), polythene (t2) and banana ...

Recent innovations in training deep convolutional neural network (ConvNet) models have motivated the design of new methods to automatically learn local image descriptors. The latest deep ConvNets proposed for this task consist of a siamese network that is trained by penalising misclassification of pairs of local image patches. Current results from machine learning show that replacing this siame...

Cell-mediated cytotoxic (CMC) activity is the main cellular immunological response to kill tumor cells, virus-infected cells and parasites (Groscurth, 1989). In mammalian species this is carried out by several leucocyte populations depending on the non-specific/innate and specific/adaptive immune response. Among the last ones, the CMC activity is carried out by cytotoxic T lymphocytes (CTLs), e...

We combined behavioral and physiological measures to compare coping style in wild-type Betta splendens and a domesticated strain selectively bred for sports fighting. We showed previously that the fighter strain is more aggressive than the wild type during experimental conditions that most closely resemble an actual fight. We predicted that compared to the wild type, the fighter strain would sh...

It has previously been shown that Siamese cats have abnormal retino-geniculate pathways. In the lateral geniculate nucleus of the Siamese cat two layers (A and C) represent the nasal retina of the contralateral eye in a normal manner. Two other layers (A1 and C1) have some segments that carry a normal retinotopically organized representation of the visual field, and other segments in which the ...

Betta livida is an endangered endemic species of wild fighting fish affected by habitat degradation and exploitation. Despite this concern, the literature on conservation betta negligible. Conservation a non-use value, whereas itself use-value because they are sought after in ornamental trade business. Therefore, contingent valuation method (CVM) was applied study to establish monetary value fo...

Studies of behavior in yellow bullheads showed that they recognized individuals of their own species by means of pheromones. After training by reward and punishment, blinded bullheads were able to discriminate between the odors of two donor fish, but they lost this ability when deprived of their sense of smell. The main source of the intraspecific chemical stimuli involved in recognition is the...

Loss of functional habitat in riverine systems is a global fisheries issue. Few studies, however, describe the decision-making approach taken to abate loss of fish spawning habitat. Numerous habitat restoration efforts are underway and documentation of successful restoration techniques for spawning habitat of desirable fish species in large rivers connecting the Laurentian Great Lakes are repor...
