Edible products from pelagic bissaria (Atherina mochon) fish.

The study was concerned with the utilization of small pelagic bissaria (Atherina mochon) fish in preparing edible, cheap, acceptable and nutritive products. The results confirmed the successful use of the mince of both the whole and beheaded gutted fish either alone or after mixing with different levels of plant sources (e.g. rice, wheat, potato, sesame butter, spices) in producing fresh fish ball, fish flour and spiced salted fish paste. Generally, the panelists preferred the products made from beheaded gutted fish mince above that prepared from whole one. The utilization of plant sources improved the technological properties of the products. The influence of processing on the chemical composition of these products was studied and tabulated.

Occurrence of Vibrio parahaemolyticus in selected marine invertebrates, sediment, and seawater around Alexandria, Egypt.

Samples of seawater, sediment, and the following invertebrates were collected from the Mediterranean Sea in the neighborhood of Alexandria, Egypt: sea urchins (Echinus spp.), clams (Tapes spp.), and wedge shells (Donax trunculus). A total of 165 samples were collected from November 1979 to July 1980. Average counts (per 100 mL or 100 g) of Vibrio parahaemolyticus content were as follows: seawater, 36; sea urchins, 349; sediment, 436; wedge shells, 534; clams, 1872. Samples collected in the summer months contained higher levels of V. parahaemolyticus than winter samples.
