“…This can be explained by the increase in microorganisms' activities which might increase the consumption of DO in these water bodies. This finding is also noted by several research groups (Rosas et al 1999;Crear and Forteath 2000;Chomicki and Schiff 2008). However, a remarkable drop in DO concentration during the highest intensity of Argulus presence, improved the Argulus' ability to live under low DO concentrations, as shown by Hoffman (1977).…”

Parasite intensity dynamics can be strongly affected by ecosystem abiotic components. We conducted this study to investigate how the intensity of Argulus sp. is influenced by physicochemical factors in three water bodies - river, fish farm, and reservoir - and to find the occurrence of Argulus sp. under different conditions. Argulus sp. specimens were collected using different methods - gill-netting 30 × 1.5 m, 40 mm mesh monofilament net and set from a small boat, beach seining and plankton net - from July 2010 until Jun 2011 at Guangdong province, China. Main water parameters taken for the assessment consisting of temperature, pH, DO, biochemical oxygen demand of 5 days (BOD5), chemical oxygen demand (COD), NH (4) (+) , total nitrogen (TN) and total phosphorus (TP). The results show that the ratio of female to male Argulus sp. during the studied period was 2.3:1. The presence and intensity of Argulus sp. were temperature-dependent and variable; pH values were lower than standers with high intensity of Argulus sp. Argulus sp. has the ability to live in low dissolved oxygen (DO) concentration. Relatively high concentrations of BOD5, COD, NH (4) (+) , TN and TP were detected with related variable intensity of Argulus sp., which is supposed to be a freshwater fish ectoparasite found in polluted ecosystems. It is concluded that the fish ectoparasite Argulus sp. have a strong potency of genetic adaptation impacted by environmental factors. However, this needs further study in order to gain insight into the question of the likelihood of adaptation to abiotic factors' variation.

“…SDA reflects the energy requirements resulting from feeding, including physical and biochemical processes such as the capture and handling of prey items, digestion, absorption of nutrients and the deamination of amino acids (for a review see [39]). SDA is a typical metabolic reaction associated with feeding (reviewed by [40]) and has been observed in a variety of crustaceans [2], [39], [41], [42]. Experiments with juvenile rock lobster Jasus edwardsii , for example, showed a significant increase in the oxygen consumption rate after feeding, while the oxygen consumption rate of starving larvae remained low [2].…”

Food Quality Affects Secondary Consumers Even at Low Quantities: An Experimental Test with Larval European Lobster

et al. 2012

The issues of food quality and food quantity are crucial for trophic interactions. Although most research has focussed on the primary producer – herbivore link, recent studies have shown that quality effects at the bottom of the food web propagate to higher trophic levels. Negative effects of poor food quality have almost exclusively been demonstrated at higher food quantities. Whether these negative effects have the same impact at low food availability in situations where the majority if not all of the resources are channelled into routine metabolism, is under debate. In this study a tri-trophic food chain was designed, consisting of the algae Rhodomonas salina, the copepod Acartia tonsa and freshly hatched larvae of the European lobster Homarus gammarus. The lobster larvae were presented with food of two different qualities (C∶P ratios) and four different quantities to investigate the combined effects of food quality and quantity. Our results show that the quality of food has an impact on the condition of lobster larvae even at very low food quantities. Food with a lower C∶P content resulted in higher condition of the lobster larvae regardless of the quantity of food. These interacting effects of food quality and food quantity can have far reaching consequences for ecosystem productivity.

“…The studies were wide ranging and included oxygen consumption (Crear & Forteath 2000, 2001a; production of ammonia (Crear & Forteath 2002 ); effect of photoperiod on growth and survival , comparison of wild and cultured adults for growth, sensory analysis and oil composition . Oliver & MacDiarmid (2000) examined blood refractive index and weight/carapace length ratios as indices of condition in juveniles.…”
