| Conch snails are large, fast-growing marine grazers that feed on detritus and film algae on rocks and soft sea bottoms. They are most easily found in shallow beaches just below the low-tide line. Though adapted to a life beneath the soft substratum like sand and silt, these gastropods have very strong crawling extremities, with which they can cling to hard surfaces. The evermore growth of the undesirable algae in marine aquariums, is one of the most annoying problem for aquarists. Conch snails are effective organisms for use in fighting with algae growing.This study was conducted to observe the reproductive activities of same species conch snails stocked in two different aquariums and to determine the effect of water parameters in this process. Water samples were taken from both aquariums weekly to measure temperature, salinity, magnesium (Mg), calcium (Ca) and hardness. Mean values of these parameters of first and second aquariums were 1320±75 mg/L and 1020±75 mg/L Mg; 388±25 mg/L and 310±20 mg/L Ca; 9.7±0.5 and 7.9±0.5 kH; 27±1 and 29±1 ppt salinity; 26±0.5 and 26±0.5 C temperature respectively. It was observed that, the conch snails were well fed and buried themselves in the sand close to the surface for several hours for laying their eggs in the first aquarium. Egg tubes fixed in sand particles in yarn-like shape, were observed in the first aquarium whereas not in the second aquarium. The diameter of yarn-like tube was measured 0.5 mm and the diameter of eggs were between 80 to100 μm. The eggs hatched 6 days after spawning and it was observed that larvae were in meroplanktonic phase. 20 days after hatching … |
