Early life stages of Northern shrimp (Pandalus borealis) are sensitive to fish feed containing the anti-parasitic drug diflubenzuron

Environmental factors affecting recruitment of northern shrimp Pandalus borealis in West Greenland waters

Survey estimates of northern shrimp Pandalus borealis biomass in West Greenland waters increased from about 178 000 t in 1998 to about 598 000 t in 2003. The increase in stock size was preceded by several consecutive years in which recruitment was substantially above average. Recruitment has been poor since then despite record high levels of female stock biomass. Rickertype stock-recruitment fu...

Lipid Condition and Survival in Shrimp ( Pandalus borealis ) Larvae

Croups of shrimp (Pandalus boreal is) larvae were reared under dif ferent food concentrat ions and types to assess changes in condit ion and survival during development. As expected, rate of growth (wet weight) was highei for la rvae fed on 300 Ar temia naup l i i .L r (San Franc isco s t ra in : 0 .0528 mg 'd ' ; Canada s t ra in : 0 .0355 mg 'd ' ) compared w i th those reared a t 150 naup l ...

Antioxidant and angiotensin I-converting enzyme inhibitory activities of northern shrimp (Pandalus borealis) by-products hydrolysate by enzymatic hydrolysis

In the present study, we investigated to the antioxidant and angiotensin I-converting enzyme (ACE) inhibitory activities of the northern shrimp (Pandalus borealis) by-products (PBB) hydrolysates prepared by enzymatic hydrolysis. The antioxidant and ACE inhibitory activities of five enzymatic hydrolysates (alcalase, protamex, flavourzyme, papain, and trypsin) of PBB were evaluated by the 2, 2′-a...

Why are Early Life Stages of Aquatic Organisms more Sensitive to Toxicants than Adults?

1.1. The selection of a suitable test species Toxicity tests are designed to determine the specific concentrations of chemicals that induce a measured effect on a target organism. However, the potency of any toxicant can be influenced by the characteristics of the chemical, as well as environmental (temperature, ph, water chemistry, salinity) and species (life stage, sensitivity, pre-exposure) ...
