Aquatic weeds & plants contribute a major role in the ecology of your fishery. This however at times with excessive growth of weeds/plants or algae can cause serious problems in ponds, interfering with boating, fishing, irrigation and swimming. Exceptionally dense growths of filamentous algae and submerged weeds will cause serious problems to fish as a result of night time oxygen depletion. This will cause the fish distress as the oxygen level rises and crashes throughout a 24 hour period.


Manual algae prevention is labour intensive, involves specialist equipment if undertaken on a big scale and is not always practical. The use of chemicals, algaecides, herbicides etc, should be used under strict supervision by experts, as it can be extremely harmful to aquatic life if used at the wrong dosage rate having a negative effect on fish, plants, and other species.


CMCS have used aquatic dyes as a method of controlling algae & submerged plant growth in ponds, lakes and reservoirs, the results have been proven over years and lots of our clients now look to us to apply this dye to keep the fast growing weeds at bay throughout the year.


The specially formulated dyes reduce the light levels available to the plants, with light being crucial to their survival this, in turn, leads to their eventual demise as a lack of vital nutrients are absorbed, hence eventually killing the plant and remedying the problem.

CMCS as a company always assess the bigger picture when we start every project and feel that the overall habitat should be optimally performing to get the best from the lake environment. We pride ourselves on always looking to restore and improve the environment, to not only help the flora and fauna to thrive but also make the site as aesthetically pleasing to the eye as possible. These are the habitat appraisals we look to carry out on each job below.


Habitat assessment – assessing the current state?

Habitat improvement – what can be improved on the site from current state?

Habitat restoration – can there be any restoration to banks, plants, woodland?

Natural food production and management – is there much production of food already on site?

CMCS has considerable experience of working with regionally and nationally important conservation sites throughout the UK.
