Abstract:

The diversification of current aquaculture practise in South Africa is crucial for the future development of the industry. The rock lobster, Jasus lalandii has been identified as a possible candidate species for shore based culture in systems similar to those used for abalone farming. Reduced Total Allowable Catch (TAC's) and an increased minimum legal size were implemented as management strategies to relieve fishing pressure on natural stocks of J. lalandii, and in turn led to increased market demand and a possible niche for farmed lobsters. High puerulus settlement along the Namibian coast,

Abstract:

The focus of my thesis research is on the interplay between individual behavior, population dynamics and community-level processes within zooplankton communities in coastal Maine. The target organisms of my thesis work are marine copepods. Copepods are small (1-10 mm) crustaceans that perform the essential ecosystem function of consuming and assimilating primary production (phytoplankton) making it available to higher trophic levels such as commercially important fishes. Therefore, copepod population growth is of critical importance to marine food webs. Fertilization limitation has been su

Eurypanopeus depressus and Eurypanopeus dissimilis, two estuarine species of xanthid crabs, were raised under laboratory conditions. Four zoeal stages and one megalopal stage were observed in both species. The larvae of E. dissimilis have a longer intermolt period and grow to a larger size than E. depressus. E. dissimilis can be distinguished from E. depressus on the basis of three main features: 1) greater telson armature, 2) longer endopod in relation to the protopod of the antenna in the fourth zoeal stage, and 3) presence of the frontal horns on the carapace of the megalopa.

Abstract:

Molting in arthropods is a complex process governed by regulatory mechanisms that have evolved and adapted over millennia to allow these animals to grow, despite being confined by a hardened exoskeleton. We isolated the molt-regulating Y-organs (YO) from the common shore crab Carcinus maenas at molt stages B, C1-3, C4, and D0 to assess how changes in protein abundances might underline the unique physiology of each of these stages. We found that changes in protein abundance were most notable in the postmolt stages (B and C1-3), where an increase in energy metabolism and the reactive oxygen spec

Abstract:

Abstract Arthropod photoreceptors are versatile sense organs. Any investigation of these organs has to consider that their structure and functional limitations at the moment of fixation depend on many factors: species, sex, developmental and nutritional state of the animal, time of day and ambient light. The microscopic image of an arthropod photoreceptor is always a sample frozen in time and space. Quite often publications on arthropod photoreceptors only provide the name of the species studied, but nothing beyond that. At least the developmental status of the study animals ought to be noted,

The isopod Saduria entomon matured during winter at an age of three years at 5 m depth in the Norrby archipelago (63° 30'N, 19° 50'E). Males matured eariier and at larger sizes (27-48 mm) than females (23-36 mm). The offspring were released

Abstract:

The blue crab, Callinectes sapidus, represents an ecologically and economically important component of marine and estuarine ecosystems. In Florida, blue crab landings accounted for $9.6 million dollars during the 2010 fishing season. Accurate stock assessments for this valuable fishery are essential. Age is a critical biological component of accurate stock assessments; however, blue crabs and other crustaceans are especially difficult to age because of the complex nature of discrete growth. Biochemical extraction of an aging pigment, lipofuscin, was developed using blue crab eyestalks. The
