Atlantic salmon Salmo salar are extensively farmed throughout their natural range, and unintentional interactions between farmed fish and wild populations have been implicated in the decline of wild salmon. The trace element composition of salmon scales distinguishes wild from farmed fish, and potentially provides a rapid and cheap method to assess the extent of escaped farmed fish within a wil...

Amidst overexploited fisheries and further climate related declines projected in tropical fisheries, marine dependent small-scale fishers in Southeast Asia face an uncertain future. Yet, small-scale fishers are seldom explicitly considered in regional fisheries management and their contribution to national fish supply tends to be greatly under-estimated compared to industrial fisheries. Lack of...

Retained foreign bodies can be a source of infection and a cause of disability. A 63-year-old white man presented with a nonhealing wound of the right second finger of 1 month's duration. The injury occurred while cleaning fish. Radiographs and subsequent wound exploration showed a retained fish scale in a finger wound. In addition to foreign bodies, atypical infectious organisms must be consid...

We compared quantity and structures of food-derived gelatin hydrolysates in human blood from three sources of type I collagen in a single blind crossover study. Five healthy male volunteers ingested type I gelatin hydrolysates from fish scale, fish skin, or porcine skin after 12 h of fasting. Amounts of free form Hyp and Hyp-containing peptide were measured over a 24-h period. Hyp-containing pe...

present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

Coral reefs are highly complex ecological systems, where multiple processes interact across scales in space and time to create assemblages of exceptionally high biodiversity. Despite the increasing frequency of hierarchically structured sampling programs used in coral-reef science, little progress has been made in quantifying the relative importance of processes operating across multiple scales...
