Generate an appropriate single-sentence summary for the given text such that it includes the main topic of the text.

Example Input: Pink salmon are native to Pacific Ocean waters but have spread to parts of northern Europe after being released into rivers in Russia in the 1960s. Fisheries Management Scotland said 2017 saw "unprecedented numbers" of pink salmon in UK rivers. It said due to the fishes' two-year life cycle the salmon could be seen again this year. There are concerns the invasive species could become established in Scottish rivers and compete with native Atlantic salmon for food. The Ness, which flows from the northern end of Loch Ness to Inverness and the Beauly Firth, and Helmsdale in Sutherland were among the rivers pink salmon were spotted in during 2017. The fish have already colonised some rivers in Norway. Fisheries Management Scotland has issued advice to anglers on what to do if they should encounter the fish this year. The national body said the fish should be humanely killed and handed over to the local district salmon fishery board for further analysis. Anglers have also been asked to report sightings of pink salmon, including their spawning activity in August and September. The invasive species spawns at a different time of the year from Atlantic salmon. In its new advice, Fisheries Management Scotland said the Scottish government had been involved in work looking at how to control pink salmon. Options being considered include allowing district salmon fishery boards and trusts to capture the fish under licence in targeted efforts. Also being looked at is the setting up of a formal framework for anglers' reports of pink salmon they catch while fishing for native species of fish.
Example Output: A non-native species of fish could return to Scottish rivers in large numbers this year.

Example Input: By Jane WakefieldTechnology reporter Rather than building vehicles from scratch, Otto will make kits to retro-fit existing lorries. The start-up, which will be self-funded, is betting on autonomous lorries becoming a reality before cars. Drivers will still be required to take the wheel on non-motorway roads. Implementing self-driving technology on US motorways is seen as being easier than on other roads or city streets. Details about when the first models will hit the road and the price of them are not yet available, although Otto has said that it would be "a fraction" of the cost of building a truck from scratch. The kit will include cameras, radar and lidar sensors which will allow the vehicle to safely keep within a lane, maintain a set speed and slow or stop when necessary. It is unlikely, at this stage, to be able to change lanes. Driverless trucks are already becoming a reality. Daimler has tested its Mercedes-Benz lorry on motorways in Germany and has also been granted the first autonomous truck licence in Nevada. In Europe, convoys of semi-autonomous driving lorries from six different manufacturers have travelled across the continent with a driver in the lead setting the speed and route and the other trucks following automatically. One of Otto's main goals will be to reduce road accidents involving drivers who work long hours. According to the National Academies of Sciences, Engineering and Medicine, there are around 4,000 fatal accidents in the US each year involving trucks or buses. Between 10% and 20% of these are linked to driver fatigue. Otto is looking for 1,000 truckers to volunteer to have self-driving kits installed on their cabs to fine-tune the technology. The American Trucking Association, the US trade group for lorry drivers, said it was looking at drawing up a policy for self-driving technology later this year. "We are paying close attention because this could be huge for trucking in terms of labour costs and safety," Dave Osiecki, chief of national advocacy told the AP news wire. San Francisco-based Otto currently has around 40 employees, including Anthony Levandowski, who built Google's first self-driving car. In an interview with technology website BackChannel, co-founder Lior Ron, ex-product boss for Google Maps, said the firm had already completed several tests of a retro-fitted Volvo cab. "We have driven on a bunch of roads in California and outside, testing the sensors. And we've done driving with a safety driver in the back seat but the truck driving autonomously, and a couple of miles completely driverless without a driver in the back seat at all." But the firm has greater ambitions, he added. "We want to get the technology to the point where it's safe to let the driver rest and sleep in his cabin and we can drive for him, exit to exit."
Example Output: A group of former employees from Google, Apple and Tesla has formed a start-up aimed at turning commercial lorries into self-drive vehicles.

Example Input: The school, part of City, University of London, was named after the figure in 2002, after a donation from the foundation that bears his name. The foundation will also change its name as it is "no longer appropriate". Both organisations acknowledged the hurt caused by the association. Sir John Cass's Foundation was set up as an educational charity in 1748. It funds work across London, concentrating especially on projects for young people. On the Foundation's website Sir John Cass is described as "a merchant and politician, whose wealth posthumously was used to create the Foundation to deliver educational benefits to disadvantaged children". However, he was also a major figure in the early development of the slave trade and the Atlantic slave economy, directly dealing with slave agents in the African forts and in the Caribbean. The university said on Monday that following broad consultations, its governing council had decided unanimously that continuing to use the name "was incompatible with City's values of diversity and inclusion". For now, the business school will be be referred to as City's Business School pending consultations about a new name. Julia Palca, head of the City Council, said: "We acknowledge the great pain and hurt caused to members of our City and business school community and to many black people by the association of the wchool's name with the slave trade. "Any continued use of Sir John Cass' name would be seen as condoning someone whose wealth in part derived from the exploitation of slavery. This is incompatible with our values of diversity and inclusivity. We have therefore taken the decision to remove the name." 'Hurt and anger' The move comes amid intense debate about the honouring of people with links to the slave trade, which has included some successful demands for the removal of statues. A statue of Edward Colston, a fellow slave trader, was also toppled in Bristol in the wake of international protests following the death of George Floyd in police custody in the US in May. A spokesman for Sir John Cass's Foundation said the charity was also now "committed to a name change". A spokesman said: "We also continued to celebrate Sir John Cass without explaining or acknowledging his connection to slavery and human exploitation or the hurt and anger this has caused amongst our beneficiaries and our community. "We recognise, acknowledge, seek to understand, and apologise for the public hurt and anger. So let us be clear: we no longer consider the Sir John Cass name appropriate to represent us and the work that we do in this century or in the future."
Example Output:
The prestigious Cass Business School, in London, is changing its name because of its associations with Sir John Cass, a 17th Century merchant and proponent of slavery.
