Composition and Distribution of Macrobenthic Invertebrate Fauna

carbon was absent in the sediments. Crustacean mean 

 biomass ranged from a low of 0.11 g/m 2 in areas of 

 highest organic carbon content to a high of 19 g/m'-' 

 where organic carbon was between 2% and 2.99%. 

 Moderately low biomasses (between 1 g/m 2 and 9 g/ 

 m ) occurred in the other carbon content classes. Areas 

 devoid of organic content also contained low mean 

 biomass (0.31 g/m 2 ). 



Rank order of the mean biomass of the dominant 

 taxa in terms of organic carbon content was as follows: 

 0%: Annelida, Echinodermata, Mollusca, Crustacea; 

 0.01-0.49%: Mollusca, Echinodermata, Annelida, Crus- 

 tacea; 0.50-0.99%: Mollusca, Echinodermata, Annelida, 

 Crustacea; 1.00-1.49%: Echinodermata, Mollusca, 

 Annelida, Crustacea; 1.50-1.99%: Echinodermata, 

 Annelida, Mollusca, Crustacea; 2.00-2.99%: Mollusca, 

 Echinodermata, Annelida, Crustacea; 3.00-4.99%: Echi- 

 nodermata, Mollusca, Annelida, Crustacea; 5.00%+: 

 Annelida and Crustacea were equal, whereas Mollusca 

 and Echinodermata were absent in this class.
