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.

Germany livestock import ban lifted

The UK government has amended its ban on the import of livestock, meat and dairy products from Germany.

Defra said the decision follows 'rigorous technical assessment' of the measures applied and the current situation. "If the situation changes, we will not hesitate to take necessary action in response to the FMD outbreaks in the European Union to protect our domestic biosecurity," it said.

The ban was implemented in January following an outbreak of foot and mouth disease (FMD) near Berlin. Personal imports of meat, milk and dairy products will remain in place at a country level.
