Aquarium Corals: Applying PAM fluorometry for the advancement of coral aquaculture

By Zack Zartler on Jan 18, 2012 at 10:00 AM

(Alaska Pacific University) While the aquaculture of corals has greatly improved with recent technological advances in water parameter regulation, flow control, and lighting, a lag persists in physiological examination of the health of coral specimens. A cost-friendly, pulse amplitude modulated (PAM) fluorometer (Junior- or JR-PAM) was used to examine photosynthetic activity of corals within recommended aqua-culturing temperature ranges. A total of 24 coral fragments were used, representing four species: Acropora sp., Montipora digitata, Pavona decussatus, and Seriatopora hystrix. Exposure to typical, aqua-culturing temperature treatments (22, 24, 26, and 28°C) for three week periods revealed significant restrictions of photosynthesis at lower- and higher-end temperatures. Both maximum quantum yield (FV/FM) and maximum, relative electron transport rate (rETR) were significantly different across the four-interval temperature range. The efficacy of the JR-PAM for in situ coral research was also examined, and usefulness for determining coral productivity was assessed.

Aquarium Fish: An Overview of Clownfish of the Saddleback Complex

By Kenneth Wingerter on Jan 04, 2012 at 10:00 AM

Members of the Saddleback Complex are among the most challenging species of clownfish to maintain in captivity. A rather high level of care must be reached to ensure (if it can be ensured) the health and wellbeing of these sensitive animals. Generally, attempts to keep these fishes should be undertaken by advanced aquarists (especially so if host anemones are to be kept as well). Properly cared for, the wide-band clownfish, the saddleback clownfish, and the sebae clownfish alike will undoubtedly enhance the beauty and distinctiveness of any marine aquarium display.
