Glenn KR, Pennuto CM. Winter residency and foraging of non-native round goby populations in Great Lakes tributary streams. JOURNAL OF FISH BIOLOGY 2023; 103:1401-1408.

Abstract
Investigations of winter diets and foraging in fish are rare, and less so for migratory species in the temperate zone. In the Great Lakes, the round goby (Neogobius melanostomus) is known to out-migrate from nearshore habitats to offshore depths in the winter months. However, in Great Lake tributaries, populations of this fish were found up to 25 km upstream during winter months. Distance upstream was a predictor of out-migration behavior with populations farthest upstream remaining as winter residents, whereas populations nearest the lakes out-migrated. Distance inland was also a predictor of fish total length, but not Fulton's condition index. Seasonal resources and local prey availability shaped the diets of these fish, but resource use remained unchanged over time since invasion. Total length and body condition also remained unchanged over time since the invasion. Plasticity in both diet and migration behavior seems to be beneficial traits for the inland invasion success of this fish.

CONSERVATION PHYSIOLOGY 2023; 11:coad094. [PMID: 38425367 PMCID: PMC10904007 DOI: 10.1093/conphys/coad094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 09/13/2023] [Accepted: 11/07/2023] [Indexed: 03/02/2024]
Abstract
Climate change will exacerbate the negative effects associated with the introduction of non-indigenous species in marine ecosystems. Predicting the spread of invasive species in relation to environmental warming is therefore a fundamental task in ecology and conservation. The Baltic Sea is currently threatened by several local stressors and the highest increase in sea surface temperature of the world's large marine ecosystems. These new thermal conditions can further favour the spreading of the invasive round goby (Neogobius melanostomus), a fish of Ponto-Caspian origin, currently well established in the southern and central parts of the Baltic Sea. This study aims to assess the thermal habitat suitability of the round goby in the Baltic Sea considering the past and future conditions. The study combines sightings records with known physiological models of aerobic performance and sea surface temperatures. Physiological models read these temperatures, at sighting times and locations, to determine their effects on the aerobic metabolic scope (AMS) of the fish, a measure of its energetic potential in relation to environmental conditions. The geographical mapping of the AMS was used to describe the changes in habitat suitability during the past 3 decades and for climatic predictions (until 2100) showing that the favourable thermal habitat in the Baltic Sea has increased during the past 32 years and will continue to do so in all the applied climate model predictions. Particularly, the predicted new thermal conditions do not cause any reduction in the AMS of round goby populations, while the wintertime cold ranges are likely expected to preserve substantial areas from invasion. The results of this research can guide future monitoring programs increasing the chance to detect this invader in novel areas.

Environmental abundances of the non-native round goby Neogobius melanostomus influence feeding of native fish predators. JOURNAL OF FISH BIOLOGY 2023; 102:1340-1357. [PMID: 36929483 DOI: 10.1111/jfb.15380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 03/12/2023] [Indexed: 06/09/2023]
Abstract
The authors assessed the importance of the round goby Neogobius melanostomus as prey for three native predatory fish species, Atlantic cod Gadus morhua, European perch Perca fluviatilis and northern pike Esox lucius, in a northern and southern area of the Baltic Proper, using a combination of visual analysis and DNA metabarcoding of predator stomach contents. To explore the influence of environmental abundances of N. melanostomus on predation, they related the occurrence of N. melanostomus in predator diets to its abundance in survey fishing. Gadus morhua and E. lucius in the southern area showed the highest tendency to feed on N. melanostomus when it was abundant, as N. melanostomus occurred in up to 100% of stomachs and constituted up to 88% of the total diet volume proportion. The diet contribution of N. melanostomus was associated with N. melanostomus abundances for G. morhua and E. lucius, and when N. melanostomus was abundant, these predators exhibited lower prey richness and a higher degree of piscivory. G. morhua and P. fluviatilis also fed less on crustacean prey when N. melanostomus was abundant. The high importance of N. melanostomus in diets of native fish predators may modify indirect interactions between N. melanostomus and native prey species in invaded coastal communities.
