To optimise crop yield, the cocoa trees require spraying with neonicotinoid insecticides (Imidacloprid, Thiacloprid Acetamiprid and Thiamethoxam). It is proposed that rainwater runoff from the treated area may pollute the Owena River and that these pesticides may thereby enter the human food chain via six species of fish (Clarias gariepinus, Clarias anguillaris, Sarotherodon galilaeus, Parachanna obscura, Oreochromis niloticus and Gymnarchus niloticus) which are cultured in the river mostly for local consumption. -

Its first sexual maturity height is 17.5 cm TL in females and 23.4 cm TL in males. Sexual dimorphism based on observation of the genital papilla is difficult to recognize. The fish species is carnivorous with rapid growth rate. For further evaluation of its aquaculture potential in Benin Republic, the current study aims to make a review on the reproductive aspect of P. obscura. Its resistance, rapid growth and high economic and nutritional values represent important potential for aquaculture because it is highly appreciated by the West African population in general. The natural stock of P. obscurais currently threatened to disappearance in Benin due to fishing pressures that lead to overexploitation. A successful rearing of P. obscura in controlled medium could ensure not only the preservation and improvement of natural stocks but also the production of food fish for sustainable aquaculture. -

All these water bodies are the house a wide variety of fish species. Diverse fish species, including Small indigenous Fish species (SIFs) were recorded by various workers from different rivers and wetlands of Assam. SIFs are considered as a source of rich food. They are the source of high-quality protein, dietary calcium, essential fatty acids, amino acids and some of the principal vitamins and minerals. Fish plays a significant role in nutrition and food security but often little recognized element in food security and nutrition. A good number of fish species are consumed as medicine by different ethnic tribes of Assam. In the present paper a review on the diversity of small indigenous freshwater fish species in Assam and their nutritional contents and medicinal importance are presented. Keywords : Fish Diversity, SIFs, Assam, Nutritional content, Ethnomedicine. I. INTRODUCTION II.

Recycled Fish Sculpture (.PDF)
Recycled Fish Sculpture Name:__________ Fish: are a paraphyletic group of organisms that consist of all gill-bearing aquatic vertebrate animals that lack limbs with digits. At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates. Sculpture: is three-dimensional artwork created by shaping or combining hard materials—typically stone such as marble—or metal, glass, or wood. Softer ("plastic") materials can also be used, such as clay, textiles, plastics, polymers and softer metals. They may be assembled such as by welding or gluing or by firing, molded or cast. Researched Photo Source: Alaskan Rainbow STEP ONE: CHOOSE one fish from the attached Fish Names list. Trout STEP TWO: RESEARCH on-line and complete the attached K/U Fish Research Sheet. STEP THREE: DRAW 3 conceptual sketches with colour pencil crayons of possible visual images that represent your researched fish. STEP FOUR: Once your fish designs are approved by the teacher, DRAW a representational outline of your fish on the 18 x24 and then add VALUE and COLOUR . CONSIDER: Individual shapes and forms for the various parts you will cut out of recycled pop aluminum cans (such as individual scales, gills, fins etc.) STEP FIVE: CUT OUT using scissors the various individual sections of your chosen fish from recycled pop aluminum cans. OVERLAY them on top of your 18 x 24 Representational Outline 18 x 24 Drawing representational drawing to judge the shape and size of each piece. STEP SIX: Once you have cut out all your shapes and forms, GLUE the various pieces together with a glue gun. -
