Population Structure of the Tub Gurnard (Chelidonichthys lucerna Linnaeus, 1758) in Türkiye Coasts Using Otolith Chemistry and Shape Analysis

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries
Chelidonichthys lucerna is an economically important demersal species. It is under excessive fishing pressure and yields from fisheries are in decline in Türkiye. Information about the species' population structure and habitat connections is limited.

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Stock Status of Ompok bimaculatus in Kaptai Lake: A Length‐Based Approach for Sustainable Fisheries Management

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Ompok bimaculatus, a silurid catfish, is a commercially valuable and endangered species in Bangladesh. Kaptai Lake is a critical habitat for this species, yet growing market demand and ecological pressures jeopardize stock sustainability. Therefore, this study employed a length‐based approach integrating LB‐SPR and aLBI to conduct the baseline

Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

The Effect of Temperature, Flow, Density and Disease on Smallmouth Bass (Micropterus dolomieu) Early Life Growth Rate

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Individual growth rates of fish are influenced by gradually changing environmental conditions and rapid‐onset events. However, there is a paucity of information on drivers of spatiotemporal variability in growth rates of fishes across large spatial extents.

Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, Volume 33, Issue 5, Page 977-989, October 2026.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key

Water temperature and river discharge drive age‐dependent changes in brown trout (Salmo trutta) growth

Journal of Fish Biology, Volume 109, Issue 4, Page 2080-2093, October 2026.
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

Climate change impacts on fish in the Baltic Sea

Journal of Fish Biology, Volume 109, Issue 4, Page 2147-2165, October 2026.
Abstract The Baltic Sea is a marginal sea with strong abiotic gradients harbouring fish of both marine and freshwater origin. Here we review the empirical evidence for how changes in climate variables have impacted different fish and fish communities in the Baltic Sea.
