| The harvestable biomass has therefore decreased to such low levels that steps must be taken to avoid reducing it any further. |
| Industrial and private owners may be most interested in producing a harvestable product for a processing mill. |
| New branches will form where the nodes remain, producing a multi-stemmed plant that becomes very bushy and full of harvestable leaves. |
| The harvestable biomass has therefore fallen substantially, so that its current level is low. |
| Recruitment has been lower than total mortality for several years, so the harvestable biomass is currently very low. |
| Reductions in harvestable shellfish resources in the Northeast and Mid-Atlantic subregions is attributed to overharvesting , disease, predation, and environmental impacts. |
