First of all, it was likely a male, not a female, if there was only one fish
present. Females deposit eggs the male has built, the male then fertilizes the eggs, and takes up watch. The female leaves. Absolutely no parental care invested by female bass (neither smallmouth or largemouth). The male stands guard over the eggs as well as the fry once they hatch, keeping sunfish, minnows, and an assortment of other critters at bay until the fry get to the size where they being to leave the nest on their own. So - the second question to ask ...... just how many eggs or fry got gobbled up in the 5 to 7 minutes it took for you to play the fish, land it, photograph it, put it back, and have it return to the nest. Most scientific studies show even a short period of time removed from the nest can result in drastic fry predation. Whether legal in your area or not, dedicated, concerned, and conservation-minded anglers should seriously question whether it's ethical to fish bedded bass, whether they should participate in such activities themselves, and just what we want for the future of our bass fisheries.

American Fisheries Society Symposium 31. Edited by David P. Philipp and Mark S. Ridgway. ISBN: 1-888569-38-7. Published January 2003 The Use of Sanctuaries for Protecting Nesting Black Bass from Angling (Pages 371-378) Cory D. Suski, Frank J. S. Phelan, Mark F. Kubacki, and David P. Philipp Catch-and-release angling for bass during the brood-guarding stage can induce premature nest abandonment by the male parent, resulting in loss of the brood to predation. Significant levels of angling-induced brood loss can cause a population-level decrease in reproductive success. If that decrease in reproductive success translates into a decrease in recruitment, the population density and/or size structure of the bass population may be affected negatively. To avoid these potential problems, managers in some parts of North America have implemented regulations designed to protect nesting male bass while they are spawning and guarding their young. The purpose of this study was to determine if Voluntary Bass Conservation Zones (areas within a lake that are closed voluntarily to all angling until the bass spawning season is over) could be used to protect these highly vulnerable bass from angling. Our results demonstrate first that with sufficient levels of advertisement and community enforcement, a Voluntary Bass Conservation Zone can both reduce levels of angling for nesting bass and increase the reproductive success of the bass population within the zone. They demonstrate second, however, that a Voluntary Bass Conservation Zone that is not properly enforced can actually decrease bass reproductive success by attracting unscrupulous anglers to bass spawning areas, thereby increasing levels of angling for nesting bass. How Well Does a Closed Season Protect Spawning Bass in Ontario (Pages 379-386) Mark F. Kubacki, Frank J. S. Phelan, Julie E. Claussen, and David P. Philipp Current management strategies for largemouth and smallmouth bass sometimes incorporate seasonal closures in spring/early summer to protect bass during their reproductive periods. Our 12-year (1990-2001) field study investigated how well southern Ontario's closed bass fishing season matched the reproductive periods of nesting male largemouth bass Micropterus salmoides and smallmouth bass M. dolomieu in two lakes and two rivers in the region. Study areas within each system consisted of two-kilometer stretches of shoreline in which bass reproductive activity was monitored visually by divers. The data collected for each nesting male included species, egg deposition date, level of mating success, duration of parental care, and whether that male was successful or unsuccessful at producing surviving offspring to the free-swimming independent fry stage. Our results demonstrate that the extent of protection afforded nesting male bass through the use of the closed season varied significantly among water bodies and among years, reflecting the variation in spring warming rates. Smallmouth bass guarded their broods at the nest site significantly longer than largemouth bass and were, therefore, vulnerable to anglers longer. In addition, visual surveys of angling activity revealed that angler noncompliance with this regulation was common and even pervasive at some sites. The annual and geographic variation in the extent of protection afforded by the uniform seasonal closure indicates that a refinement of that regulation may be beneficial. Furthermore, the substantial levels of preseason angling observed in several of the study sites indicate that some other method of protection (e.g., sanctuaries or total closed seasons) may be more effective in many instances. |

Also consider how many lakes get stocked by people, how many fewer people remove fish from lakes as they can buy food at the local store, and a thing called "nature". Ignoring all that, I think you _might_ have a point. |
