Experimental study with replica bows and projectiles of a variety of types indicates the superiority of archery over the throwing of spears, and makes it possible to indicate a hierarchy of increasing efficiency in the main classes of bows.

Alaska pollock was headed, gutted, and frozen at sea in pre-and postrigor condition. Surimi made from this fish held at -29°C showed a gradual loss in gel-forming ability with time of storage. This loss in gel-forming ability was accompanied by a loss in viscosity and Ca+ +-ATPase activity of the surimi over the g-month storage period. The gel strength of kamaboko gels showed an inverse linear relationship with gel moisture over a limited moisture range. Simply freezing and thawing pollock resulted in surimi with significantly lower gel strength than that from fresh pollock.
