Biotechnology Input in Fish Breeding
Pisciculture, to increase the fish production, has a crucial limitation. Fish cultured in land-locked water bodies usually do not breed without the hormonal induction. Technology of fish breeding suffered for a long time due to the lack of suitable commercial product to induce the spawning of economically important fish. Hypophysation technique, where pituitary extract was used to induce the br...
متن کاملForests fuel fish growth in freshwater deltas
Aquatic ecosystems are fuelled by biogeochemical inputs from surrounding lands and within-lake primary production. Disturbances that change these inputs may affect how aquatic ecosystems function and deliver services vital to humans. Here we test, using a forest cover gradient across eight separate catchments, whether disturbances that remove terrestrial biomass lower organic matter inputs into...
متن کاملLandscape Effects on Breeding Songbird Abundance in Managed Forests
We examined the relationship between songbird relative abundance and local and landscape-scale habitat variables in two predominately midto late-successional managed National Forests in the southern Appalachian Mountains, USA. We used partialregression analysis to remove correlations between habitat variables measured at different spatial scales (local habitat and square landscape regions with ...
متن کاملFish and harlequin ducks compete on breeding streams
We investigated interactions among harlequin ducks (Histrionicus histrionicus (L., 1758)), fish, and their shared aquatic insect prey. We measured flow variability, benthic aquatic prey abundance, fish presence, and breeding density of harlequins on eight rivers in the Southern Coast Mountain Range in British Columbia, Canada, in 2003 and 2004. Rivers with lower flow variability had higher abun...
متن کاملInvestigation of biological characteristics and breeding potentials of some species of surgeonfish (Family: Acanthuridae) inhabiting the Persian Gulf for exploitation in the ornamental fish breeding industry
The coral reefs of the Persian Gulf are among the richest coral reserves systems in the world. These valuable habitats have a remarkable diversity of aquatic species, especially fish. One of the important ecological groups living in coral reefs of the Persian Gulf is surgeonfish (Family: Acanthuridae), which have been considered by researchers in many studies. These fish can be introduced as br...
