FISHES 



The fish fauna of Surrey is essentially a freshwater one, but owing 

 to a part of the Thames being under tidal influence it possesses a few 

 marine types which extend into its limits. A complete list of Surrey 

 fishes has not appeared before. 



TELEOSTEANS 



ACANTHOPTERYGII 



1. Perch. Perca flimia tills, Linn. 



2. Ruff or Pope. Acerina cernua, Linn. (A. 



vulgaris, Day). 



Common in the Thames above Richmond. 



3. Miller's Thumb or Noggle-head. Cottus 



gobio, Linn. 



ANACANTHINI 



4. Flounder. Pleuronectes flesus, Linn. 



Yarrell records it as occurring in the 

 Thames as high as Sunbury near Hampton. 



HEMIBRANCHII 



5. Three - spined Stickleback. Gastrosteus 



acu/eatus, Linn. 



The smooth form (G. /iurus, Cuv.) alone is 

 found in inland ponds and streams, whilst the 

 varieties with bony shields on the sides (G. 

 tracburus, G. simiarmatus, Cuv.) occur in the 

 tidal part of the Thames. 



6. Ten - spined Stickleback. Gastrosteus 



pungitius, Linn. 



More local. Known from Battersea and 

 Cobham. 



HAPLOMI 



7. Pike. Esox lucius, Linn. 



OSTARIOPHYSI 



8. Carp. Cyprinus carpio, Linn. 



Introduced from Asia to Europe in the 

 twelfth or thirteenth century. First men- 

 tioned in England in 1496. 



9. Crucian Carp. Cyprinus carassius, Linn. 



Both the typical form and the gold-fish (C. 

 auratus, Linn.) have been introduced in ponds, 

 and are now fully acclimatized. 



10. Barbel. Barbus vulgaris, Flem. 

 Abundant in the Thames. 



1 1 . Gudgeon. Gobio ftuviatilis^ Flem. 



12. Rudd. Leuciscus erythrophthalmus, Linn. 



13. Roach. Leuciscus ruti/us, Linn. 



14. Chub. Leuciscus cephalus, Linn. 



15. Dace. Leuciscus dobula, Linn. (L. vul- 



garis, Day). 



1 6. Minnow. Leuciscus phaxinus, Linn. 



17. Tench. Tinea vulgaris, Cuv. 



1 8. Bream. Abramis brama, Linn. 



19. Bleak. Alburnus lucidus, Heck. & Kner. 

 Common in the Thames. 



20. Loach. Nemachilus barbatula, Linn. 

 In small streams. 



MALACOPTERYGII 



21. Salmon. Salmo saiar, Linn. 



The salmon, which was once abundant in 

 the Thames, can no longer be claimed as a 

 member of this county's fauna, no capture 

 having been recorded since 1821. Several 

 attempts have been made since 1862 at re- 

 introducing the fish, the latest of which (the 

 first of a series which are to be carried on for 

 some years to come) took place in April, 1901, 

 when between 500 and 600 samlets, reared 

 at Denham near Uxbridge, were turned into 

 the river just below Teddington weir.
