Recent Research: Finfish • Use of freeze-dried krill for feed training of largemouth bass (Kubitza and Lovshin, 1997) • Use of inosine-5-monophosphate as a feed enhancer (Kubitza et al., 1997) • Use of krill hydrolysate as a feed attractant (Kolkovski et al., 2000) • Improved growth and performance of striped bass fed a plant feedstuff-based diet (Papatryphon and Soares, 2000) • Feeding stimulants for young yellowtail (Hidaka et al., 2001) • Effect of feeding stimulants on diet preference by juvenile gibel carp (Xue and Cui, 2001)

Crustacean Meals • • • • • • Shrimp waste meal is a reasonably good feed ingredient, if heads are included otherwise, the shell is primarily chitin and of limited digestibility the ammonia in chitin accounts for about 10-15% of the nitrogen in whole meal also a reasonable source of n-3 fatty acids, cholestrerol and astaxanthin (carotenoid) highly palatable and often serves as an attractant in feeds at 1-2% others: krill meal, Artemia meal krill meal

Commercial whaling in Antarctic Ocean     Baleen whales: 1 million a century ago eat Antarctic krill (4% of body weight) Now, less than 200,000 Other krill-dependent predators such as seals and penguins have been found greatly increased in abundance Competition release due to the dramatic decrease in baleen whale population

• Gamekeeper’s Thumb – Cause of Injury • Sprain of UCL of MCP joint of the thumb • Mechanism is forceful abduction of proximal phalanx occasionally combined w/ hyperextension – Signs of Injury • Pain over UCL in addition to weak and painful pinch • Tenderness and swelling over medial aspect of thumb – Care • Immediate follow-up must occur • If instability exists, athlete should be referred to orthopedist • If stable, X-ray should be performed to rule out fracture • Thumb splint should be applied for protection for 3 weeks or until pain free © 2010 McGraw-Hill Higher Education.

1.1 Outside Your Comfort Zone Scenario 2 • One of your company’s employees is on international travel to negotiate an important contract. In a room full of his/her foreign hosts, the employee is given a thumb drive to load a critical file to his/her laptop that is necessary for the meeting. The employee is worried that rejecting the thumb drive could offend the hosts and jeopardize the contract. • Which FSO’s can say your employee would not load the thumb drive? 13

Table 10.13: Intrinsic Muscles of the Hand: Fine Movements of the Fingers • Small, weak muscles that lie entirely within palm of hand control precise movements of metacarpals and fingers (example: threading a needle) • Abductors and adductors of fingers produce opposition—move thumb toward little finger • Flexion: thumb bends medially along palm, and fingers bend anteriorly • Extension: thumb points laterally, and fingers move posteriorly © 2016 Pearson Education, Inc.

Hand: Metacarpus and Phalanges • Metacarpus • Five metacarpal bones (#1 to #5) form the palm • Phalanges • Each finger (digit), except the thumb, has three phalanges—distal, middle, and proximal • Fingers are numbered 1–5, beginning with the thumb (pollex) • Thumb has no middle phalanx Copyright © 2010 Pearson Education, Inc.

Right Hand Rule What is the difference between your left and right hand? After all, index finger always is between thumb and middle finger. Weak rule: magnetic field around a current in thumb direction is in direction of fingers Strong rule: force on a current in thumb direction in a field in index direction is in middle finder direction
