چکیده
The longspined sea urchin, Centrostephanus rodgersii, is a climate-driven pest species in south-eastern Australia. harvest of this highly encouraged and Tasmania, the existing fishery expanding resulting large amount waste that needs disposal. Research into use products as inputs for organic or biodynamic farming systems can help reduce costs disposal keep industry profitable; by sustaining incrementing urchin assist their control. In current study, was dried finely ground to powder applied tomato plants greenhouse examine effect on growth productivity. Urchin (UWP) had mineral composition Ca (40 g 100 g−1), Mg (1.7 P (0.03 Fe (19.34 mg kg−1) B (38 kg−1), pH 8.06 water an Electrical Conductivity (EC) value 7.64 dSm−1. Seven different treatment rates UWP (0.3%; 0.5%; 0.8%; 1%; 2%; 3%; 5%), were added 10 replicate pots containing 4 kg nutrient-poor potting mix planted with (Variety K1) seedlings. Plant growth, yield, quality attributes content measured under treatments comparison against Hoagland solution influenced productivity proportional quantity applied, however, control significantly greater yield. Potting increased from 6.8 7 higher available detected receiving UWP. No phytotoxic effects detected. highest matched fruit nutritional composition. Processing has potential fertiliser amendment providing plant-available some microelements such Boron.

Adaptive Capacity of the Habitat Modifying Sea Urchin Centrostephanus rodgersii to Ocean Warming and Ocean Acidification: Performance of Early Embryos
BACKGROUND Predicting effects of rapid climate change on populations depends on measuring the effects of climate stressors on performance, and potential for adaptation. Adaptation to stressful climatic conditions requires heritable genetic variance for stress tolerance present in populations. METHODOLOGY/PRINCIPAL FINDINGS We quantified genetic variation in tolerance of early development of t...
متن کاملThe sea urchin complement homologue, SpC3, functions as an opsonin.
The purple sea urchin Strongylocentrotus purpuratus expresses a homologue of complement component C3 (SpC3), which acts as a humoral opsonin. Significantly increased phagocytic activity was evident when yeast target cells were opsonized after incubation with coelomic fluid containing SpC3. SpC3 could be detected on the surface of yeast, and phagocytic activity could be inhibited by an anti-SpC3...
متن کاملBiotechnology for aerobic conversion of food waste into organic fertilizer.
A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...
متن کاملAn Individual-based Fishery Model and Assessing Fishery Stability
The stability of a fishery system was investigated using two forms of a stochastic computer simulation model that was individually based in terms of the fishing boats. Fish catch was partitioned among boats according to two catch processes: an unranked process in which all boats had equal ability to catch fish and a ranked catch model in which a boat’s ability to catch fish depended on its weal...
