Fish cold-blooded‚ limbless‚ completely aquatic vertebrates‚ having gills‚ commonly fins‚ and typically elongated torpedo-shaped body mostly covered with scales. Fish are usually grouped into four classes‚ three living (Agnatha‚ Chondrichthyes‚ and Osteichthyes) and one extinct (Placodermi): 1. Agnatha‚ the primitive jawless fishes‚ including the cyclostomes (lampreys and hagfishes) and extinct armoured fishes known as ostracoderms‚ none of which has gill arches (bony frames for the gills);

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the

CHAPTER 1 INTRODUCTION BACKGROUND OF THE STUDY Fish is abundant in the Philippines and is the cheapest source of protein‚ thanks to advances made in aquaculture or fish farming. Aquaculture is contributing significantly to food security‚ livelihood‚ and the economy. It involves raising seaweeds‚ milkfish‚ tilapia‚ shrimp‚ oysters and mussels in tanks or enclosures‚ ponds‚ pens‚ cages and open coastal waters. Fish Farming has been practiced over a hundred of years. It is a viable‚ sustainable

The Fish by Elizabeth Bishop Bishop uses literary devices‚ especially similes‚ metaphors‚ tone‚ and imagery to convey her theme of admiration for survivors of life’s difficult battles‚ in this case the fish‚ although at first she failed to admire and appreciate the fish. Bishop also doesn’t realize how beautiful the fish is at first‚ but she eventually finds beauty in the fish. Bishop’s tone of aloofness in lines 5-10 shows that first she is disappointed in what she thought was a big catch.
