Chinook salmon spawner stocks in California's Central Valley, 1989: annual report

This report covers the 37th annual inventory of chinook salman, Oncorhynchus tshawytscha, spawner populations in the Sacramento-San Joaquin River system.-It is a compilation of reports estimating the fall-, winter-, late-fall-, and spring-run salmon spawner populations for streams which were surveyed. Estimates were made from counts of fish entering hatcheries and migrating past dams, froro surveys of dead and live fish and redds on spawning areas, and from aerial counts. The estimated 1989 total escapement of chinook salmon in the Central Valley was 205,990 fish. This total consisted of 181,864 fall-, 12,171 spring-, 539 winter-, and 11,416 late-fall-run spawners. All of the spring-, late-fall-, and winter-run salmon were estimated to be in the Sacramento River system, while 3,493 fish of the fall run were in the San Joaquin River system. Due to decreases of spawner populations in most Central Valley tributaries, the total 1989 salmon stock was 32% lower than in 1988; however, late-fall salmon in the upper Sacramento River had a run size similar to that of 1988. The winter run in the mainstem Sacramento River was at a record low level. (PDF contains 44 pages.)

Indol als moglicher Indikator fur nicht einwandfreie hygiensiche Be- bzw. Verbarbeitung tropischer Garnelen

Indole concentrations of 114 samples of tropical shrimp, 3 samples of crayfish, and 3 samples of cold water crustaceans were determined. Cold water crustaceans contained less than 15 μg/kg indole, whereas crayfish contained between 62 and 123 μg indole/kg. In 81 samples (70 %) of tropical shrimp indole content was less than 50 μg/kg, but in 12 samples (11 %) indole content exceeded 250 μg/kg. Different batches of some products with high indole levels as well as of some products with low indole levels were analysed. Except for one sample high as well as low indole levels could be confirmed. Highest indole concentrations were determined in samples which origin was specified as South Pacific, Indo-Pacific, Malaysia, India and India/Vietnam

Fish and fisheries of Bakolori Reservoir

Details are given of fisheries activities carried out in Bakolori Reservoir within the context of many and varied functions of Sokoto Rima River Basin Development Authority. Experimental fishing was conducted for 55 days in 1979 when the reservoir was only one year old and the exercise continued in 1980 and 1981 also for 85 and 52 days respectively. During the exercise, the catch per unit effort showed an increasing trend with increasing efforts by four times to that of the initial. The fish harvest was 1.205 kg/day when 3.8 nets were operated in 1979, this went up to 3.2 kg when the number of nets were increased to 8.37/day in 1980. This increasing trend continued in 1981 season also when 16.15 nets caught 5.756 kg fish per day. A direct relationship was observed in the fishing efforts and catch. Tilapia, Clarias, Labeo, Schilbe and Synodontis spp, were the most predominant fish species in the catch and contributed more than 97% of the total fish harvest

Trace metals -- a potential threat to our fishing industry

Trace metals constitute a major form of water pollutant that can adversely affect fish production. The potentially toxic metals have been identified as lead, zinc, copper, arsenic, antimony, mercury beryllium, barium, cadmium, chromium, nickel, selenium among others. Preliminary laboratory studies have been directed to the determination of traces of lead in the aquatic biota and its toxicity. There are indications that the levels reported in effluents from some of the industries may be above the tolerant limits of local fish species and organisms that make up their food. Metal pollution could become a serious problem to freshwater fisheries in the future as a result of increasing urbanization and industrialization, unless efforts are made to prevent it
