| 31. | For prime conditioning ( especially if captive reproduction is to be attempted ) live foods such as " Daphnia " should be offered.
|
| 32. | Over time, however, Daphnia adapted to be able to feed on the blue-green algae, helping to control it in the lake.
|
| 33. | The bream are then forced to live by filter feeding with their gill rakers, " Daphnia " water fleas being the main prey.
|
| 34. | It can take as long as 6 months to raise fry to juvenile sizes where they are capable of eating live daphnia on a regular basis.
|
| 35. | Two experimental systems are used in Murdoch's research : the " Aphytis "-California Red Scale and daphnia-algae systems.
|
| 36. | A study showed that " Daphnia pulicaria " is competitively superior to " D . lumholtzi " in the absence of predators.
|
| 37. | The inflexion point in the " Daphnia " population density graph occurred at half the carrying capacity, as predicted by the logistic growth model.
|
| 38. | In this condition the tentacles are very difficult to see with the naked eye and are often only revealed when a prey animal such as Daphnia is caught.
|
| 39. | More fish tended to disperse in the patch with less daphnia ( the sought after food source ) and the more abundant patch had a shortage of visitors.
|
| 40. | FAO described thiamethoxam as non-toxic to fish, daphnia and algae, mildly toxic for birds, highly toxic to midges and acutely toxic for bees.
