JUMPSTART- Greenwater Hapa-based Tilapia Fingerling Production System

JUMPSTART- Greenwater Hapa-based Tilapia Fingerling Production System The 2015-2016 Jumpstart programme was designed to support on-going activities to boost tilapia production in Trinidad through the delivery of technical advice to fish farmers and the provision of fingerlings. A hapa-based green water nursery system was implemented in 2016 for tilapia fingerling production. The environmental, biological and economic aspect of such a fingerling production system was documented, and will be used to create a manual to be made available to tilapia farmers....

Feasibility Study on the Use of a Land-Based Integrated Multi-Trophic Aquaculture (LB-IMTA) System

Feasibility Study on the Use of a Land-Based Integrated Multi-Trophic Aquaculture (LB-IMTA) System in the Treatment of Wastewater Released From a Marine Re-circulated aquaculture SYStem (RAS) This project aims to improve the operations of the marine recirculating aquaculture system (RAS).  A land-based integrated multi-trophic aquaculture (LB-IMTA) system capable of treating nutrient-rich water exuded from the shrimp (Penaeus vannamei )culture tanks within the marine RAS was installed in an attempt to reuse water.  The purpose of introducing this infrastructure is not only to improve the economic viability for this marine shrimp species, but also attempt to create a stand-alone marine production model capable of being situated...

Socio-economic Baseline Assessment of the Shellfish (oyster and crab) Harvesting Activities in the Gulf of Paria

Socio-economic Baseline Assessment of the Shellfish (oyster and crab) Harvesting Activities in the Gulf of Paria Over time pressure from human activities exerted upon wetlands situated on the west coast Trinidad (Caroni Swamp, Godineau and Rousillac) have impacted on the livelihoods of those working in the shellfish industry.  To further our understanding of the on-going impacts of development on wetland dependent livelihoods, this project establishes a socio-economic baseline on shellfish gatherers working from the wetland of the west coast of Trinidad. An interim report was produced based on an analysis of the questionnaire issued....

Age and Growth Studies of the Marine Invasive Pterois Volitans (Lionfish) from Early Invasion in Tobago Waters

Age and Growth Studies of the Marine Invasive Pterois Volitans (Lionfish) from Early Invasion in Tobago Waters The second known marine Invasive Alien Species (IAS) in Trinidad and Tobago, is the Lionfish, Pterois volitans.  Introduced into the Atlantic Ocean from the Indo-Pacific, the Lionfish, was first captured in Castara, Tobago in July 2012 and at Saut D’eau, on the north coast of Trinidad in July 2013 completing its spread throughout the region.  Within the Caribbean, predicted impacts include competition with native species for prey and habitat, direct predation on native species, and altered native fish community structure. Research aimed at managing these impacts requires improved...
