Group 4

Marine fauna

Pollution along the coast is usualy due to both farming and urban, industrial activity

Most urban and industrial dumping is legally in order (each

pollutant keeping within the bounds). However, not always are the size and frequency of

dumping in the same area taken into account.

Group 4 has gathered information about the quality of sea water along our coast focusing

the attention on a research on shellfish which prove to be particularly suitable to be

used as chemical, microbiological and toxicological pollution indicators; being filter-feeders, they draw nourishment from filtering water which enables them to stockpile large

quantity of chemicals, bacteria, viruses, algal cells and/or toxic principles inside their

digestive tissue.

The results of this research reveal that ...

chemical parameters keep within the legal bounds on most part of the coastline, while

microbiological analyses point out the presence of coliform in some more densely

populated areas.Only Cumae coastline (north of Naples)

appears to be heavily influenced by a big purification plant dumping which prevents

shellfish from living.

Marine fauna in the Gulf of Naples is the same as in the Tyrrhenian sea

It is very rich in the so-called “Blue fishes”

Besides “blue fishes” there is a large variety of different

species like:

Sardina

Sardina pilchardus

Alice (o Acciuga)

Engraulis encrasicholus

Sgombro

Scomber scombrus

Aguglia

Belone Belone

Marvellous conger eels often peep out from dark caves and

indentations Gronchio

Along cymodocea and Neptune grass

prairies you can run into sea horses

Cavalluccio marino

Hippocampus Guttulatus

Starfish lying on sandy plains.

Stelle marine

Astropecten Aranciacus

In Spring and Autumn John Dory fish, which normally lives in deep sea,

comes up to the surface Pesce San Pietro

Zeus Faber

Scorpion-fish lay their eggs near the rocks

Scorfano

Scorpaena Scrofa

Among seafood, the little known red sea urchin is particularly worth

mentioning: an unmarketable dainty

Riccio Rosso

Astropyga Radiata

Nudibranchi

Ipselodoris valencenniens

Nudibranchi may be found on the rock walls

On the seabed there are expanses of poseidonea and gaudy gorgonias

There are areas where black coral...

Corallo nero

Gerardia Savalia

…and pink coral can be found.

Corallo rosa

Dendrophillia ramea
