Aquaculture Hyperbooks Turbot Technical Pages
These pages contain technical advice on the cultivation of turbot. They are complimented by economic modelling tools that enable you to explore how a potential turbot cultivation business might work. There are models for the hatchery and on-growing aspects of farming.

Aquaculture Hyperbooks Clam Technical Pages
These pages contain technical advice on the cultivation of Manila and native clams. They are complimented by economic modelling tools that enable you to explore how a potential Manila or native clam cultivation business might work. There is a model for each species. Key words: Aquaculture; Mussel; Scallop; Oyster; Clam; Halibut; Turbot; Cod; Manila; Pacific; Hyperbook; Economic; Model; cultivation; farming; King; Queen; algae; trestle, rope; cage; seabed; suspended; hatchery; nursery; production; -
Effects of electrofishing for Ensis spp. on benthic macrofauna, epifauna and fish species. SR652
This report summarises the results of experimental work carried out as part of “Design and Trials of Electrofishing System for Razorclams – FIFG 57437 and Seafish IPF funding project C85”. The aim of the project was to design and trial methods of harvesting Ensis spp. using electrical stimulus with the intention of providing a more environmentally benign alternative to existing hydraulic and toothed dredges. The results of this study demonstrate that the effects of electrofishing gear employing relatively low DC voltage and amperage can be effectively used in the harvest of Ensis spp. without serious negative effects on the epifaunal and macrofaunal benthic community. -
Seafood-waste disposal at sea – a scientific review
Due to the recent tightening of regulations surrounding the disposal of seafood processing waste to landfill, fish and shellfish processors are now facing a rise in the cost and difficulty of waste disposal. This is of particular concern in remote areas where alternative uses (e.g. fishmeal) are neither accessible nor economically viable and therefore, cost effective and environmentally-sound solutions to the disposal of this waste need to be found. This report examines the potential for disposal at sea, together with the likely impacts and advice on the selection of appropriate sites for disposal.
