- 10 greatest wildlife spectacles on the planet<\/a><\/strong><\/li>\n<\/ul>
<\/p><\/div> <\/section>
The spectacle of salmon leaping up their natal river can be traced back to a previous autumn when they started their lives as pea-sized eggs laid by their mothers in gravelly riverbeds. In April or May, they hatch as \u2018alevins\u2019 before becoming fry and feeding on aquatic invertebrates.<\/p>\n
The minority that are not picked off by predators will then steadily develop into larger \u2018parr\u2019 with distinctively patterned flanks. Depending on water temperature and food availability, they might spend several years in the river system before a silvery sheen replaces the parr marks and they undergo a physiological change in preparation for saltwater.<\/p>\n

Anywhere between 15 and 50 months will be spent feeding in rich deep-sea waters on a diet of crustaceans, post-larval sandeels and small fish. While food is plentiful for the maturing salmon, there are also many predators, such as sharks, seals, dolphins and humans, meaning only about 10 per cent of the smolts that initially leave the rivers will ever be able to return back to freshwater.<\/p>\n
Bottlenecks such as rapids and waterfalls are the best places from which to watch salmon leaping <\/blockquote> <\/div> <\/div> <\/div>\n<\/div>
How they pilot back is still unclear, but it\u2019s thought they use a combination of the Earth\u2019s magnetic field and knowledge of ocean currents. Arriving at the coast, they probably locate their natal river by recalling a \u2018chemical memory\u2019 imprinted as smolts. Upon entering the estuaries, another transformation occurs when the breeding \u2018tartan\u2019 is developed.<\/p>\n
The females, called hens, become much darker, with a rainbow colouration along their flanks, while the males, otherwise known as cocks, develop red bellies, streaky flanks and a large hook, called a kype, that protrudes outwards and upwards from their lower jaw.<\/p>\n

How do salmon leap upstream?<\/h2>\n
Relying solely on the reserves put down at sea, the salmon are made up of rippling muscle and use their strength and agility to power up the river<\/a><\/strong>. The movement of the fish tends to be dictated by rainfall, with a higher flow rate actually making it easier to work their way past a variety of obstacles en route to their spawning grounds.<\/p>\n
Justifiably famed for their leaping abilities, the height they are able to jump depends on the \u2018run-up\u2019 the plunge-pool at the base of any waterfall allows for. Driving up from the river bottom into the air, the aim is to jump over any watery obstruction, with a leap of over 3m not uncommon. Dropping back into the water the other side, they propel themselves forward against both the current and gravity with vigorous contractions of their tail. Many leaps seem to end in heroic failure as fish are thrown back into the \u2018washing machine\u2019 down below, but the majority usually end up passing the obstacle \u2013 particularly when water levels are higher.<\/p>\n

To see the action, why not try using either an aquascope or an underwater camera? However, please do be careful on the wet, slippery banks and rocks at the water\u2019s edge. \u00a0<\/span><\/p>\n
What happens during spawning?<\/h2>\n
In the shallow spawning stretches upriver, you may be able to see the hen salmon digging a series of shallow depressions, called redds, in the gravel. Any eggs subsequently deposited will then be by fertilised by an attendant cock salmon who has successfully fought off the opposition.<\/p>\n
The spawning process further upriver can be so exhausting that over 90 per cent frequently die once the eggs have been laid and fertilised. Although a few post-spawning salmon, called kelts, do seem capable of returning to the sea and spawning again in future years.\u00a0<\/span><\/p>\n

How can I spot leaping salmon?<\/h2>\n
To see salmon leaping, bottlenecks such as rapids and waterfalls are undoubtedly the best place from which to watch, with early mornings and late afternoons being when the fish are most active, as well as after heavy rainfall. A good vantage point is ideal, and once you\u2019ve identified where salmon are leaping you can then move closer for a better view. So why not swim against the current of popular opinion yourself, by catching what is surely one of our most underrated wildlife spectacles?\u00a0<\/span><\/p>\n
Do any animals prey on salmon?<\/h2>\n
All manner of predators will eat salmon parr in rivers, such as goosander, grey heron, kingfisher<\/a> and mink<\/a>, but the only animal capable of taking on a mature salmon swimming upriver to spawn will be an otter<\/a>. Look out for their distinct spraint piles \u2013 smelling of jasmine tea! \u00a0<\/span><\/p>\n

T<\/b>he Falls of Shin, Sutherland<\/b><\/a><\/h3>\n
This Highland waterfall on the River Shin in Achany is famed for its leaping salmon, and offers a lookout from which to watch the action, with a visitor centre located close by.<\/p>\n

The narrow waterfall on the River Almond is undoubtedly one of the best places for viewing leaping salmon in all of Scotland and a favourite spot with photographers.<\/p>\n

Standing on the banks of the River Tyne, salmon can be seen leaping up this weir as they head to spawning grounds further upriver in the Pennines.<\/p>\n
G<\/b>ilfach Nature Reserve, Powys<\/b><\/a><\/h3>\n
When the River Marteg is swollen with rain this reserve, managed by Radnorshire Wildlife Trus<\/a>t, is a great place to catch both salmon leaping and otters trying to intercept them.<\/p>\n

The Salmon Viewing Centre near Selkirk offers the opportunity to learn all about the salmon\u2019s life-cycle before seeing the fish in action at \u2018the cauld\u2019 \u2013 a large weir a short walk away.<\/p>\n
