... Total yields climbed to 4 times the maximum of previous fisheries for native species. In the view of human communities on Lake Victoria's shores, Nile perch was "the saviour" (Greboval 1990). ...

... Offtakes could further be improved through provision of market information (in the media) on the number of goats traded and prices as observed by Njwe (1992), and increasing the number of livestock auction centres for increased accessibility by farmers. The accruing income would allow the farmers to carry out village-wide disease prevention which is more effective and economical (Oppong, 2006), or train their own AHAs. ...

... The use of initial low concentrations of these glucosinolates allowed for the monitoring of the reaction, despite the baseline of the electropherogram was slightly disturbed due to the interaction of the isothiocyanates with the micelles. In-vial derivatization with amines or thiol containing compounds such as GSH, results in the production of the corresponding hydrophilic thioureas or dithiocarbamates (Fig. 2) [49], which were also found to be detectable by the developed procedure (data not shown). ...

... The largest scombrotoxin poisoning outbreak in the United States was related to consumption of canned tuna, where the histamine levels were 680 to 2,800 ppm (37). High levels of histamine in commercially produced canned fish products have occurred worldwide and are primarily due to temperature abuse before canning (33,41,43). Tuna for canned trade are mostly processed from fresh catch that is frozen at sea and later thawed, butchered, partially cooked (or precooked), and cooled. ...

... Because PUFAs such as α-linolenic and linoleic acids cannot be synthesized in mammals, they are essential FAs (i.e., required in the diet) [4,5]. These PUFAs not only exert a hypocholesterolemic effect against coronary heart disease and hypertension when used as food supplements, but also are critical for the development of infants during pregnancy and breastfeeding periods [6-8]. ...

... Mass transfer is the most important phenomenon in algal cultivation systems and must be effectively assessed to optimize the amount of nutrients (solid particles) dissolved in liquid water [8,27]. Estimating the mass transfer between nutrients and water of the TLC system contributes to achieve the optimum nutrient concentration and enhance the algal productivity. ...

... In this article, the species in each species group are first aggregated, and the "average" intrinsic growth and carrying capacity is estimated as a group, treating each species group as single species by using the surplus production model. Further discussion on aggregating species into groups using a surplus production approach, can be found in the following literature: Fogarty, Overholtz, and Link (2012); Anderson (1977); FAO (1978); Pope (1979Pope ( , 1980; Saila and Roedel (1980); Caddy (1980); Marten and Polovina (1982); Ursin (1982); Pauly (1982); Pauly and Murphy (1982). ...

... Singh and Jambunathan (1982) studied protein concentration in a different part of pigeonpea and analyzed that embryo consist of high albumin protein content than that of other parts of the seed. Reddy et al. (1979) reported the outer layer is rich in protein content in comparison to the inner layers of cotyledons. Dehulling of whole grains of pigeonpea removes husk and germ, and outer layers of the cotyledon (rich in protein) are converted into a very fine powder which comes in the fraction B (<0.25 mm) through an electro-magnetic sieve shaker and, thus, fraction B is the richest fraction in protein. ...

... Both approaches met with little success as the opaque-2/floury-2 combination did not result in translucent kernels and the opaque-2/sugary-2 combination resulted in a severe yield penalty of almost 20% over that of normal types. Another approach is to alter the germ-endosperm ratio that has the dual advantage of increasing both protein content and quality (Bjarnason and Pollmer, 1972; Poey et al., 1979; Vasal et al., 1980). The germ has almost double the amount of protein and is of better quality than the endosperm however, increasing the germ size contributes to poor shelf life of maize and will be an obstacle in some countries which throw away the germ before preparation of food products (Vasal, 2001). ...
