Twin-tail goldfish strains are examples of drastic morphological alterations that emerged through domestication. Although this mutation is known to be caused by deficiency of one of two duplicated chordin genes, it is unknown why equivalent mutations have not been observed in other domesticated fish species. Here, we compared the chordin gene morphant phenotypes of single-tail goldfish and comm...

Mycobacteriosis is a chronic disease of freshwater and marine fish. In the present study, Mycobacterium fortuitum from a diseased gold fish, Carassius auratus was isolated and identified by biochemical and molecular (PCR) method. The isolate was found to be resistant to rifampicin, isoniazid, pyrazinamide and ethambutol and myoconda® a nanodrug combination of rifampicin, clarithromycin and clof...

The hunting strategies of pelagic thresher sharks (Alopias pelagicus) were investigated at Pescador Island in the Philippines. It has long been suspected that thresher sharks hunt with their scythe-like tails but the kinematics associated with the behaviour in the wild are poorly understood. From 61 observations recorded by handheld underwater video camera between June and October 2010, 25 thre...

Background Fish is one of the main culprit foods in childhood allergy [prevalence below 5 years 30% and then 9.8%, Spain]. IgE-mediated fish allergy diagnosis (FAD) is based on specific IgE (sIgE) detection to fish whole extracts and parvalbumin, considered to be major allergen, despite oral challenge (OC) is still the gold standard. Parvalbumin is an important panallergen. Cod parvalbumin (Gad...

To improve the pre-cracking behavior and post peak strength of concrete composites, a new variety natural fiber called Fish Tail Palm Fibers was used as micro reinforcement in concrete. (FTPF) are completely renewable resources available abundance, many parts country including India. Three different volume fractions, (0.1%, 0.2% 0.3%, three lengths fibers (10 mm, 20 mm 30 mm) were chosen parame...

An increasing number of low-grade gold ore deposits are characterized by the presence of gold as solid solution into the mineral matrix of sulphide minerals which is not directly amenable to gold cyanidation. In order to liberate this submicroscopic gold the ore has to be oxidized before being subjected to gold cyanidation and exctraction. This is mainly done by autoclave pressure oxidation (AC...

The understanding of fish maneuvering and its application to underwater rigid bodies are considered. The goal is to gain insight into stealth. The recent progress made in NUWC is reviewed. Fish morphology suggests that control fins for maneuverability have unique scalar relationships irrespective of their speed type. Maneuvering experiments are carried out with fish that are fast yet maneuverab...
