Nutrient requirements and feeding of Haddock
The development of feeds for potential new marine fish species for aquaculture must be based on sound information regarding the nutrient requirements, digestion, absorption and retention of major nutrients and energy utilization from various feed ingredients. Until recently, the field of haddock nutrition remained unexplored. Our preliminary research has shown that diet containing high amounts of protein (50-55%), low carbohydrate (<14%), low lipid (<15%) with a sufficient amount of n-3 long chain polyunsaturated fatty acids (1.5-2.0 % eicosapentaenoic and docosahexaenoic fatty acids) and well fortified with vitamins and trace elements is suitable for initial feed formulations of haddock growout diets. Higher amounts of dietary lipid (>12%) cause fatty liver and an increase in hepatosomatic index. The role of certain critical nutrients (protein and amino acids, essential fatty acids, minerals, vitamins), energy utilization, feeds and feeding for haddock is briefly reviewed.NRC publication: Ye

Protein and energy nutrition of marine gadoids, Atlantic cod (Gadus morhua L.) and haddock (Melanogrammus aeglefinus L.)
Primary goals of this thesis were to: 1) examine the in vivo digestion of macronutrients from conventional or alternative feed ingredients used in practical diets of juvenile gadoids (Atlantic cod and haddock), 2) document growth potential of fish at the juvenile grower phase given varying levels of dietary protein and energy and 3) assess the potential of in vitro pH-Stat methods for rapid screening protein quality of feed ingredients, specifically for gadoids. All primary research questions were linked to and built upon one another with the goal of gaining a better understanding of protein and energy utilization of juvenile grower phase gadoids. Studies showed that cod and haddock have a high capacity to utilize a wide range of dietary feed ingredients, such as fish meals, zooplankton meal, soybean products (meal, concentrate and isolate) and wheat gluten meal. New dietary formulations for gadoids may also utilize pulse meals, corn gluten meal, canola protein concentrate and crab meal. Digestibility data in this thesis is currently the only research that examined both in vivo and in vitro macronutrient digestibility of a large number and wide range of individual ingredients, specifically for gadoids. This is essential to gain new knowledge on protein and energy utilization as well as for least-cost ration formulations and effective substitution of ingredients into new formulations. Data has demonstrated a dietary digestible protein/digestible energy (DP/DE)ratio of 30 g DP/MJ DE is required for gadoids during the juvenile phase (in vitro closed-system pH-Stat assay for rapid screening protein quality of test ingredients that is ‘species-specific’ to gadoids. It is demonstrated that in vitro results generally reflected results obtained through conventional in vivo protein digestibility methods. Studies resulted in the first generation of a ‘gadoid-specific’ proteolytic enzyme extraction method and in vitro closed-system pH-Stat assay which may be useful to investigate protein digestion, absorption and metabolism of gadoids and further development of their feeds. </p

A description of two new species of the genus Erenna (Siphonophora: Physonectae: Erennidae), with notes on recently collected specimens of other Erenna species
Two new Erenna species, E. insidiator sp. nov. and E. sirena sp. nov., are described from specimens collected in the vicinity of Monterey Bay, California, and also, for E. sirena at the southern end of the Gulf of California, Mexico. Further information on the three extant Erenna species is given, based on specimens collected in the same areas. These have enabled, for instance, the identification of three types of tentilla on the tentacles of E. cornuta Pugh, 2001, rather than the two noted on the single previously known specimen. The genus is remarkable for the presence of bioluminescent lures on the tentilla of all five species. In E. sirena sp. nov. the tentilla are also covered by a red-fluorescent layer, which was briefly described by Haddock et al. (2005), and further details are given herein. Another extraordinary feature of the colonies E. sirena sp. nov. is that the main part of the tentacle, with its tentilla, can be extended away from the siphosomal stem on a long peduncle. This phenomenon also appears to occur in E. laciniata Pugh, 2001, and has not been observed before for other physonect species
The mentoring cycle
The aim of this chapter is to explore the mentoring cycle and in particular, the concept of phases within the context of the mentoring relationship. The chapter begins by outlining a number of models that describe how mentoring relationships develop over time, such as Kram (1980, 1983), Missirian (1982), Clutterbuck (1985; 2004), and Westland (2015). The mentee and mentor perspective is explored by understanding the experiences of each, through insight, during various stages of the relationship. Next, the author identifies a number of empirical studies that have ‘tested’ the models to better understand their application to specific contexts (Westland, 2015). The models are compared and contrasted in order to identify the challenges associated with the concept of the mentoring cycle. The author also considers factors that influence the mentoring cycle and the effectiveness of the mentoring relationship. Finally, the author considers the implications of the mentoring cycle from a number of perspectives: mentoring relationships, program design, training for mentees and mentors, and future research agendas for both researchers and practitioners
