New Caledonian crows Corvus moneduloides use tools made from sticks or leaf stems to 'fish' woodboring beetle larvae from their burrows in decaying wood. Previous research on this behaviour has been confined to baited sites, leaving its ecological context and significance virtually unexplored. To obtain detailed observations of natural, undisturbed tool use, we deployed motion-triggered video c...

The nematode Anisakis simplex is a parasite spread worldwide which infects consumers of raw or barely cooked fish. Clinically, it manifests itself in varied ways, from asymptomatic patients to others with allergic or digestive symptoms depending on the part of the digestive tract in which the larva lodges. We here present a case of incidental discovery of colonic eosinophilic granuloma, seconda...

Zebra danios (Brachydanio rerio) swim in a burst-and-coast mode. Most swimming bouts consist of a single tail flick and a coasting phase, during which the fish keeps its body straight. When visualising the flow in a horizontal section through the wake, the effects of the flow regime become apparent in the structure of the wake. In a two-dimensional, medio-frontal view of the flow, larvae and ad...

We describe the presence of anisakiasis in a patient who had a small hiatal hernia. A 60 year-old women presented general malaise, burning pain, flatulence, persistent nausea and abdominal distension during five days before consulting. She referred that she ate a dish of marinated raw fish with lemon and pepper ("cebiche") and after a few hours the symptoms began. An esophagogastroscopy showed ...

A preliminary study was conducted on the efficacy of Oryzias melastigma in consuming mosquito larva so as to control mosquito and mosquito borne diseases, and enhancing its reproductive success using supplementary feed. Oryzias melastigma is a larvivore fish and widely distributed in the shallow water, wetlands of Gangetic plains and peninsular India. These studies indicate that O. melastigma i...

The presence of nematode or round worms in the flesh of marine fish has long been known and is perceived to be both an aesthetic and human health problem. The most abundant group are members of the genus Anisakis and within fish they are small, colourless worms which are found, often lightly coiled within the flesh or the viscera. Within the flesh they are often difficult to see with the naked ...

Community service activities for catfish aquaculture with tarpaulin ponds in Tuatuka, East Kupang District, Nusa Tenggara Province. The problems are the potential of natural resources that have not been optimized and desire Agape Farmer Group who wants to progress but is constrained by limited knowledge making ponds, preparation media, stocking larva, maintenance, feeding, monitoring water qual...

The infection status of marine fish and cephalopods with Anisakis simplex third stage larva (L3) was studied over a period of 1 year. A total of 2,537 specimens, which consisted of 40 species of fish and 3 species of cephalopods, were purchased from the Cooperative Fish Market in Busan, Korea, from August 2006 to July 2007. They were examined for A. simplex L3 from the whole body cavity, viscer...

Anisakidosis, human infection with nematodes of the family Anisakidae, is caused most commonly by Anisakis simplex and Pseudoterranova decipiens. Acquired by the consumption of raw or undercooked marine fish or squid, anisakidosis occurs where such dietary customs are practiced, including Japan, coastal regions of Europe, and the United States. Severe epigastric pain, resulting from larval inva...
