Growth rates of larval and juvenile bigeye scad Selar crumenophthalmus in captivity
Growth rates of larval and juvenile bigeye scad Selar crumenophthalmus reared in captivity were studied. The results are presented, discussed, and compared to wild S. crumenophthalmus and other pelagic fish. S. crumenophthalmus are a small pelagic carangid fish of circumtropical distribution. Larvae were reared in a modified mesocosm system and sampled daily for growth. Larvae grew to a mean si...
متن کاملSome Biological Aspects of Bigeye Scad, Selar crumenophthalmus from Bangaa Faru, Maldives
In this paper, we studied some biological aspects of big eye scad (Selar crumenophthalmus) from Maldives. The fish sample was collected from the local fish market at Bangaa Faru, Male, Maldives. The length of the samples were ranged from 7.7 cm to 24.5 cm (mean value = 16.85 ± 2.82 cm) in fork length. Body weight ranged between 8 g to 255.6 g (mean value = 87.76 ± 40.41 g). The exponent values ...
متن کاملA new species of Henneguya (Myxozoa) in the big-eyed scad (Selar crumenophthalmus) from Hawaii.
We describe a new myxozoan, Henneguya akule n. sp., infecting the carangid fish Selar crumenophthalmus in Hawaii. Spores were found only in the aortic bulb, characterized by elliptical capsule with 2 tails, and pyriform polar capsules that angled toward the anterior end of the spore. Polar filaments had 3-4 coils. Parasites were present in apparently healthy fishes and caused no evident gross p...
متن کاملRelationships between larval nutritional experience, larval growth rates, juvenile growth rates, and juvenile feeding rates in the prosobranch gastropod Crepidula fornicata
Planktonic larvae experiencing short periods of starvation or reduced food supply often grow and develop more slowly, have poor survival, fail to metamorphose, metamorphose at smaller sizes, or grow slowly as juveniles. In this study, we examined the impact of short periods of food limitation at various stages of larval development on larval and juvenile growth in Crepidula fornicata. In additi...
متن کاملSchooling properties of an obligate and a facultative fish species
Schooling fish species are conventionally subdivided into obligate and facultative species, depending on the proportion of the time spent in structured schools, but little is known about the factors affecting the group structure in the absence of external structuring stimuli such as food sources, risk of predators or water flow. Changes in attraction and repulsion indicators, depending on the s...
