This paper presents a review of Great Lakes fishery assessment problems and addresses the variety of fisheries, the special circumstances created by rehabilitation, the emergence of joint strategic planning among fishery agencies, and convergence of water quality and fishery management. The inferences that emerge are that (1) continuing observation series are essential, (2) the variety of needs calls for a variety of assessment approaches, and (3) assessment objectives need to be clearly defined in order to protect the ongoing monitoring series. It is suggested that more attention should be given to fish community monitoring, to sport fishery statistics, and to gear calibration. On the other hand, improved coordination of human and material resources and focus on integration of water quality and fisheries assessment can achieve much, without great funding increases.

Fish Survival

Jinan City is the first pilot city for the construction of a hydroecological civilisation in China. Fifty-eight representative river sampling stations were selected through field trips and surveys, and fish were sampled in the spring, summer, and autumn of 2015. An index of fish biological integrity in Jinan City was constructed and to evaluate the hydroecological health of rivers. Canonical correlation analysis was used to select key driving factors that affect the health of the fish community. The results show that the key physical factor affecting water quality was turbidity, the key chemical factor affecting water quality was chemical oxygen demand (COD) and the key hydrological factor affecting water quality was discharge. Of all the driving factors, COD had the greatest effect on the health of the fish community, followed by discharge and turbidity. Macropodus chinensis Bloch was sensitive to changes in COD; Saurogobio dumerili Bleeker and Pseudolaubuca engraulis Nichols were sensitive to the hydrological factors of discharge and flow velocity; and Saurogobio gymnocheilus Lo and Squaliobarbus ourriculus Richardson were sensitive only to discharge. COD and discharge had a strong effect on fish survival, whereas turbidity affected fish survival but was not a major factor affecting the spatial distribution of river health. The findings can provide a reference for aquatic ecological rehabilitation in developing countries.

Insufficient Time

The zoobenthos of Bowland Lake is described prior to, and for 2 yr after, neutralization of the lake from pH 4.9 to > 6.0 and reintroduction of lake trout (Salvelinus namaycush). Observed changes in the total abundance, biomass, and size structure of shallow and profundal zoobenthos assemblages were attributable to changes in the fish community, not to improvements in water quality. A shift toward increased importance of oligochaetes, more representative of nonacidic conditions, occurred. However, many common, acid-sensitive taxa of zoobenthos which were absent prior to neutralization had not appeared within 2 yr after treatment, indicating insufficient time for recolonization.
