Decapods form the backbone of global crustacean fisheries and aquaculture. Palinurids contribute a small percentage of global decapod catches but are of high commercial value. They are currently ra...

Biological body parameters of adult male West Coast rock lobsters, Jasus lalandii, of commercial size were analysed over two years to determine reserve accumulation during two moult (i.e. growth-) cycles. Two fishing areas were compared that were his

An understanding of the effect of key intrinsic and extrinsic factors on the oxygen consumption of Panulirus homarus rubellus is imperative for the development of optimized transport, holding and growout protocols. This study investigated the effect

An understanding of the ammonia excretion dynamics of the east coast rock lobster Panulirus homarus rubellus is necessary to inform suitable holding, growout and transport protocols. The effect of body weight, emersion, daily rhythm, feeding and ambi

In South Africa's Western Cape Province, numbers of bank cormorants Phalacrocorax neglectus breeding at 11 localities decreased from above 500 pairs during 1978–1987 to 350 pairs from 1995 to 2006. The most northern colony (Lambert's Bay) was extin

Although acoustic tracking has been used to study the movement of several species of clawed and spiny lobsters, only recent technological advances have provided sufficiently small transmitters to examine the utility of using acoustic tracking as a me

Increased fishing effort may downwardly bias indices of abundance, such as catch-per-unit-effort (CPUE), due to gear saturation. A field experiment was developed to assess gear-saturation effects on an index of relative abundance used for stock-asses

The availability of resources and their suitability for subsistence and small-scale commercial fishers in South Africa were assessed and appropriate options for the management of resources recommended. Assessment of current resource utilization and r

Diets of male and female West Coast rock lobster Jasus lalandii in South Africa were compared across a large size range of 10–85 mm carapace length (CL). The diets of male rock lobsters were compared between two different depths, different seasons,

Accurate determination of diet is important in ecological studies. Many macrobenthic predators fragment their prey so finely that identification of component organisms is difficult. Knowledge of the food available to masticatory predators such as lob
