Background: The problem in the development of Genetically Improved Tilapia brought about by the protein from the expensive fish feed is the surprising cost of fish feeds. The study's aim is to look for an alternative and cheap fish feed. The research identified Genetically Improved Farmed Tilapia (GIFT) growth and survival rates in the HAPA using formulated sweet potato granules and commercial feeds as the grounds for the development of a Technology Guide. The experiment method has been used in the research. Results: The findings showed that the three formulated feeds have lower protein (20.33, 19.3, and 19.6) yet with higher fat (24.1, 15.69, and 10.72) than the commercial (24.1%, 3%). The initial and final weight in grams, length in centimeters and width in centimeters were highest on T1 then followed by T2 and T3. It was with the use of T1 which proved to be an effective feed. Conclusion: The ingredients utilized in the feed formulations are possible substitution of fish feed and the advancement of its usage is commendable.

The present study describes the habitats, life cycle, larval growth, burrowing behavior and terrestrial adaptation of spadefoot toads (Pelobates syriacus) in Israel based on observations and data collected over more than 30 years in northern Israel. The distribution area in Israel is from the north in the Upper Galilee and Golan Heights (annual rainfall range of 500–1000 mm) to the southern coastal plain (annual rainfall of about 250 mm). Among the 51 different breeding places of amphibians, only ponds where water is available for a few months of the year were used by spadefoot toads and metamorphosed populations were found around these ponds. The larvae underwent metamorphosis during the summer and autumn in northern Israel, and during the spring in central and southern Israel. The percentage of toads burrowing was negatively correlated to soil moisture levels, i.e., greater burrowing behavior occurring under dry conditions. Plasma concentrations of electrolytes and urea increased during burrowing. The burrowing behavior helps the spadefoot toads survive in this area at the southern border of its distribution. Spadefoot toads are highly specialized and have a narrow ecological niche that selects for lower levels of diversity.

The mangroves of Andaman and Nicobar constitute 12.39% of the total area of mangrove of the country. They are recognized as the best mangroves in the country as regards density and growth. About 99% of mangrove lies in Andaman Island and only 1% fall in Nicobar Island. They serve as a unique habitat for various fishes, crustaceans, aquatic organisms, birds, crocodiles, monkeys, etc. These rich and most productive ecosystem forms a basis for the food chain in the sea and coastal waters. They provide fuelwood, charcoal, timber, and wood chips and also helps to stabilize the shoreline and filter the land runoffs and green walls for soil erosion, thus key in stabilizing the loose soil from high wind velocity, tidal surges, and cyclonic storms. But in recent years the mangrove cover of the Islands has reduced from 686 km2 to 616 km2 showing a 10.20% decline. The major reason behind is the undervaluing of the ecosystem, as well as climate change implications.

The internal bonds created in milk gelation with chicken pepsin were approached by the use of dissociating agents-sodium dodecyl sulfate (SDS), urea, ethylenediamine tetraacetic acid (EDTA) and compared to those with rennet gel. Gels viscoelasticity aspects and microstructure were studied using rheological dynamic non-destructive measurements and Scanning Electron Microscopy (SEM) respectively. Results showed that no significant differences (p>0.05) in protein interactions between the two types of gel, with hydrophobic binding dominance in protein gelation. Viscoelasticity and microstructure also showed a similarity in the viscoelastic properties and in milk aggregation micelles mode, obtained by chicken pepsin or rennet.
