AQUARISTA JUNIOR PDF

Zooxanthellae within stony corals Porites sp. Black light nm was found to promote photosynthesis. Long-term experiments are in the planning stages. Determination of efficient photosynthetically speaking light sources is important for several reasons. Economy in the costs of maintaining a coral reef aquarium certainly is a concern, but the health of zooxanthellae and hence their animal host should be of primary importance. Aesthetic concerns, such as the promotion of coral coloration through expression of fluorescent proteins and non-fluorescent chromoproteins, are of interest to many.

Feeding behavior depended on fish size. Fish 30—50 mm either visually fed or pump-filter fed depending on zooplankton size. Electivity and feeding rate increased with prey length, but were distinct for similar-sized cladocerans and copepods. They fed non-selectively on cyclopoid copepodites, had intermediate electivities for calanoid nauplii and small cladocerans, and had highest electivities for large cladocerans, cyclopoid adults, and calanoid copepodites and adults.

Apparently, few stereotyped feeding behaviors have evolved during the acquisition of microphagy in fish. Shift in feeding modes allows these two species to optimally exploit the variable and dynamic patchy distribution of planktonic resources.
