The production of same sex Oreochromics niloticus to enhance better and uniform growth for Tilapia culture has called for technological means using sex-reversal hormones Methyl Testosterone (MT), this study will look into the percentage growth and survival of Oreochromics niloticus fry.

Awareness of Community on Fishery and Aquaculture Production in Central Ethiopia

The study was conducted in three different districts Gumer, Enemornaener and Cheha Woreda on awareness and perception of community on fishery and aquaculture production

Effects of Photoperiod Regimes on Growth Performance of Heterobranchus bidorsalis (Geoffrey St. Hilaire, 1809) fingerlings under Laboratory Conditions

Environmental factors are known to influence growth and survival of aquatic organisms. Varying intensities of light can be of great advantage to catfishes

Ranching Lake Nasser’s Nile Crocodiles

The Nile Crocodile Crocodylus niloticus is the most widely distributed crocodile species in Africa, occurring in almost all sub-Saharan countries. It was included in Appendix I in 1975. Egypt submitted a proposal (no. 9) to the IUCN at the Conference of Parties (CoP) no. 15 to transfer the Egyptian population of C.niloticus from Appendix I to Appendix II for purposes of ranching

Biosynthesis Of Nanoparticles - A New Horizon In Fish Biomedicine

The biogenic nanoparticle has becoming a significant potential technology as the result of phytomining which revealed that metals are usually deposited in the form of nanoparticles. The various biological agents in the form of algae, plants and microbes have emerged as an efficient candidate for the synthesis of nanoparticles.

First Hydroacoustic Assessment Of Fish Abundance And Distribution In The Shallow Sub-Basin Of Lake Titicaca

For the last two decades, a rapid eutrophication process impacts Lake Titicaca, the largest tropical freshwater lake in South America and the main highest Great Lake. This is especially notorious in the Bolivian sector of its shallow Lago Menor sub-basin. Lago Menor is deteriorated by the combination of multiple contaminations (domestic, industrial and mining) from untreated wastewater discharged from the urban area of El Alto, indiscriminate overfishing, and climate change. These threats particularly affect the native Andean killifish genus Orestias, the ecology and dynamics of which require in-depth studies with non-invasive techniques.

Emerging Sustainability Issues And Management Needs Of Booming Aquaculture Production Of Introduced Pangasianodon Hypophthalmus (Sauvage 1878)

Pangasius production has greatly expanded in India covering over 42,500 ha of ponds and tanks and also 2500 cages. It is mostly produced in small ponds (0.4 ha) by small farmers commonly producing 40-45 tons/ha but larger ponds above 4 ha having 1.5 to 2 m deep are many producing 80-85 tons/ha. West Bengal is the main hub of seed production, supplying over 700 million fry, while few commercial nurseries and hatcheries have recently come up in the states of Andhra Pradesh, Chhattisgarh, Odisha and of late Uttar Pradesh.

Small-Scale Fisheries Production And Rural Livelihoods: A Case Of Lake Mutirikwi (Lake Kyle), Zimbabwe

This study was conducted on Lake Mutirikwi, Zimbabwe, to determine the annual fish production and the role of small-scale fisheries in rural livelihoods. Fish production data (catch and effort) were obtained from fishers’ records. Information on fishers’ demographics and livelihoods was obtained through a questionnaire survey. A total of 30 fishers were interviewed.

Utilization Of Poultry By-Product Meal As An Alternative Animal Protein Source In The Diet Of Nile Tilapia (Oreochromis Niloticus)

This study was conducted to determine the possibility of using Poultry by-Product Meal (PBM) as an animal protein source for feeding Nile tilapia fry and determining its optimum inclusion level. The study continued for 8 weeks in four 300-liter fiberglass tanks. Each tank was stocked with 40 fry of an average weight of 4.4 g. Fish in the first tank were fed a control diet without (PBM), whereas the fish in the second, third and fourth tanks were fed diets containing 5%, 10% and 15% PBM, respectively. Diets were formulated according to their protein contents, and each contained 35% protein. The diets were made in the form of pellets
