In 2014, the Atlantic mud fiddler crab Uca pugnax was found 80 km north of its previously known northern range limit. Two years before this shift was noted, we collected a total of 781 male and female specimens from 6 populations along a latitudinal transect extending from Wareham, Massachusetts (41.7615°N), to Tybee Island, Georgia (32.0139°N), USA. By assessing latitudinal and seasonal patterns in the hepatosomatic index (HSI; a measure of stored energy) and the reproductive status of females, we sought to determine whether adult physiological and reproductive limits might slow the northern expansion of U. pugnax. We did not find a latitudinal cline for HSI, suggesting that U. pugnax is a thermal generalist; however, both males and females in the southern part of the range showed greater seasonal fluctuations in HSI compared to northern conspecifics. Across the range, ovigerous females had a significantly reduced HSI, revealing the cost of reproduction. Ovigerous females were found in the May 2013 collection in Massachusetts be fore ocean conditions were permissible for larval development and earlier than previously reported for this species. U. pugnax is expected to closely track warming conditions in the Northwest Atlantic because adults in northern populations are able to maintain energy stores comparable to that of their southern conspecifics, and they release planktonic larvae in early spring, maximizing their dispersal potential.

Compensatory growth: Fitness cost in farmed fish and crustaceans

Feed restriction in fish and crustaceans is gaining interest due to its unusual acceleration of growth after a feed deprivation period. This phenomenon, known as compensatory growth, allows deprived organisms to reach the weight of never‐stressed counterpart organisms. Since feed is the major economic and ecological burden of fish and crustaceans farming, succeeding to reduce its quantity without loss of production may enhance a sustainable aquaculture development. A wide variety of restriction/feeding protocols, involving differences in nature, duration and intensity, have been tested on aquatic organisms. However, not all of them lead to optimal compensatory growth. Furthermore, before extending this practice to industrial setting, it is essential to assess physiological costs associated with both food restriction and compensatory growth. Indeed, although fish and crustaceans appear to be tolerant to dietary restriction, it involves metabolic, digestive, oxidative and immune changes. Nevertheless, return to basal values is not always achieved through refeeding. Compensatory growth has been observed and described in many taxa; however, physiological mechanisms during this process are poorly understood. On the other hand, the acceleration of growth itself appears to generate physiological consequences in organisms, particularly through the generation of oxidative stress. This review provides an overview of the fitness consequences associated with dietary restriction and the subsequent enigmatic compensatory growth in fish and crustaceans.

“…In other latitudes and in several decapod species, the effect of different diets on the metabolite profile, digestive enzymatic activity and digestibility has been studied (López‐López, Nolasco, Villarreal‐Colmenares, & Civera‐Cerecedo, ; Pavasovic, Anderson, Mather, & Richardson, ; Rosas, Cuzon, Gaxiola, Arena, et al, ; Sacristán et al, ; Velurtas, Diaz, Fernandez Gimenez, & Fenucci, ). Furthermore, metabolic issues have been studied in another species of aeglid crustacean under laboratory culture conditions (Ferreira, Hack, Oliveira, & Bond‐Buckup, ; Oliveira, Hack, Almerão, Bond‐Buckup, & Dutra, ; Silva‐Castiglioni, Valgas, Machado, Freitas, & Oliveira, ). In organisms of A. uruguayana from their natural environment, metabolite profile was determined in various tissues (Musin, Rossi, Diawol, Collins, & Williner, ), as well as the enzymatic digestive activity of lipases, total proteinase and amylase (Musin, Rossi, Diawol, Collins, & Williner, ).…”

The aims of this study were to evaluate the short‐term effects of artificial diets with different protein: cellulose ratios (D1 = 60:0, D2 = 45:15 and D3 = 30:30) on the enzymatic activity and metabolite profile and to probe the suitability of the amino acid profile of the different diets in Aegla uruguayana. The different artificial diets affected the digestive total protease and amylase activities in a short period of time. Lipases were not affected by the diets. In the haemolymph, an effect of the diet was found in glucose and triglyceride measurements. Particularly, the glucose of the organisms fed D1 was significantly lower than that of organisms fed D2, without significant differences in D3. The concentrations of triglycerides were different among organisms subjected to the treatments, indicating a greater concentration in organisms fed D2 than in those fed D1. In muscle tissue, the concentration of glycogen followed the same trend as haemolymphatic glucose, indicating that the organisms fed D2 had a higher concentration of this metabolite compared to the rest. The amino acid profile of muscle tissue of wild and fed aeglids had a high and significant correlation in all cases, showing few changes in the short‐term feeding regime. Some changes were observed mainly in aeglids fed D3, which exhibited the lowest amounts of methionine, lysine and arginine and the highest amounts of aspartic + glutamic acids. In addition, D2 has a good quality of EAA, fulfilling almost all the requirements of a wild aeglid.
