Environmental differences in fish

Scientists reveal contrasts in fish of same species

A recent study has revealed that the parasitic communities of fish can differ greatly within the same species depending on its location.

Although every body of water on earth contains a unique variety of species and organisms, it has previously been unknown how largely this can affect fish of the same species living within the same region.

A recent study, published in the Journal of Parasitology, has revealed that fish of the same species, living in lakes just 1.5 miles (2.5 kilometres) apart, have different parasitic communities.

One of the lakes has been minimally affected by human factors, whereas, five species of non-indigenous fish have been added to the other.

The two species studied, which are both native to the lakes they inhabit, showed a a difference in parasites due to contrasts in their environment.

Furthermore, the research showed that average lengths and weights between fish of the same species were also "significantly different" as a result of environmental factors.

Scientists say further investigation is needed to find specific reasons that fish of the same species, living in lakes so close to one another, can be so different.

Lords Committee opens Pet Parasite Medication inquiry

The House of Lords Environment and Climate Change Committee will launch its inquiry into Pet Parasite Medication (PPM) on Wednesday (3 June).

Focusing on treatments containing fipronil and imidacloprid, the inquiry will seek to understand distribution pathways and the impacts of PPM use and non-use on biodiversity and human health. It will also cover current regulation, monitoring, and the potential implications for pets and their owners.

The committee will hear evidence from environmental non-governmental organisations and research institutes. The public can follow the proceedings live on Parliament TV or in person in the Palace of Westminster.
