Unsustainable over-fishing and over-exploitation have initiated the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to classify sea cucumbers as endangered species.
The species’ life histories are complex and stock enhancement programmes designed must allow released juveniles to complete their life cycle and contribute to spawning biomass.
With survival of sea cucumbers aggravated by flood, radioactive contamination, global warming and coral reef degradation, a green biotechnological approach (artificial propagation and mariculture) is needed to sustain supply for desired bio-compounds, while sustaining an eco-desired wild stock.
CITES is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survivals.
Universiti Sains Malaysia researcher Prof Madya Dr Farid Che Ghazali said through research, the university developed the La Maison Stichopodidae, a species-specified soft engineered calcium carbonate fossils-stabilised reef invention.
“It is the first ever enriched reef for Stichopodidae viability and propagation designed in compliance and fulfilled recommendation as in ‘Guideline for Marine Artificial Reef Materials, 2004’,” he said.
Dr Farid said located at Telok Rotan, Pulau Redang, in Terengganu, these reefs integrate well with agematic cloning practices and consists of two main casts.
“Echinodermata reefiness (nocturnal biological characteristics, environment and anatomy) was incorporated into their design,” he said.
He said as a waste-to-benefit effort, the echinoderm’s geochemical signatures [ancient clam shells/mussels (Class: Bivalves; Phylum: Mollusks), dried corals (Acropora sp., Dendrogyra cylindricus sp.) and silica pebbles\, was formulated with Portland cement, creating a durable cube measured at 8.88N/mm2.
