Comments on US Policy towards Aquaculture
|
With the prevailing financial situation and the need to create jobs, has the American government given any thought to intensifying domestic aquaculture production to reduce imports and create more jobs in the sector?

What is the prospect of GMO in Aquaculture?
The use of genetically modified organisms (GMOs) in agriculture and livestock farming has raised environmental and social concerns. Can it be expected that GMO in aquaculture will also spur resistance from ecologists, environmentalists and the general public?

Aquaponics
I’ve spent this weekend attending my 10 year university reunion and worked on my Aquaponics setup in my backyard.
I’ve got the fish side of things figured out but may need to read up a little more on the plant aspects.
Just a few more bits and bobs and we’re good to go!

What type of salt is used for treating fish ailments??
The literature often says to avoid iodised salt. Rock salt, aquarium salt and sea salt are the recommended safe options. But this study tells us may be we don’t need to worry so much…

| Abstract: | Salt (NaCl) is a common therapeutant in fish culture. The use of salt containing iodine may be harmful to fish. The goal of this study was to determine if using iodized saltfor dips and baths increases morbidity/mortality of fish and establishes the LC50of iodine for three commercially important species: koi, Cyprinus carpi;guppy, Poecilia reticulata;and Jack Dempsey, Rocio octofasciata. Fish were exposedto a salt bath (4 g/L) or a salt dip (25 g/L) using either iodized or non-iodized salt and observed for clinical signs of iodine toxicity or death. For the LC50trials, one fish of each species was exposed to a range of iodine concentrations for a period of 24 h. There were no significant differences in mortality between fish treated with iodized vs. non-iodized salt. The use of iodized salt for baths and dips appears to be safe in the three species tested. LC50of iodine in these species appears to be greater than 1.4 mg/L. | ||||||||||||||||

| Abstract: | Four isonitrogenous (30% crude protein) and isocaloric (4.40 kcal/g) experimental diets were formulated to contain 0.0% (control), 0.5%, 1.0%, or 1.5% cinnamon. The diet containing 1% cinnamon resulted in significantly greater (P 0.05) contents due to cinnamon supplementation. Blood plasma profile showed an improvement in hemoglobin (HB), red blood cell (RBCS), hematocrite (PCV), total protein, and total lipids, while there was a decrease in creatinin, urea, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and glucose in fish fed 1% cinnamon. Cinnamon was found to have an antibacterial activity antagonistic to Aeromonas hydrophilainfection in fish. Performance and FCR improvement translated into a 10% decrease in feed costs associated with the 1% cinnamon diet. | ||||||||||||||||

Abstract: The stress response of wild and captive reared rainbowfish (Melanoteania duboulayi) following chasing by a simulated predator was examined. Cortisol release rate was monitored using a flow through system by measuring water borne hormone levels. Tests using known cortisol concentrations revealed that the technique yielded 95% of the cortisol present in the water. Cortisol release rates increased several fold in both populations after being chased but peaked at different time periods. Wild fish showed a typical stress response with release rate rising to (2.29±0.22ngg-1h-1) 2h after exposure followed by rapid recovery. The captive-reared population by contrast showed an atypical response with cortisol release rate peaking 4h post exposure but reaching only half the level of the wild fish (1.19±0.11ngg-1h-1). The implications for the release of hatchery-reared fish for stock enhancement are discussed. Citation: Amina Zuberi, Sinan Ali, Culum Brown .
