ATTACHED IS A STOCK ASSESSMENT SUMMARY UPDATE FOR THE NASS RIVER (PDF FORMAT) FROM THE NISGA'A FISHERIES AND WILDLIFE DEPARTMENT OF NISGA'A LISIMS GOVERNMENT. SAYT-K'IL'IM-GOOT.

ALL DATA PRESENTED IN THIS UPDATE ARE PRELIMINARY AND SUBJECT TO CHANGE WITH FURTHER ASSESSMENT INFORMATION THAT BECOMES AVAILABLE AND SHOULD BE INTERPRETATED CAUTIOUSLY FOR IN-SEASON ASSESSMENT PURPOSES ONLY.

NASS FISHWHEEL OPERATIONAL NOTES:

FISHWHEEL ASSESSMENT DATA UP TO SUNDAY 27 JULY 2008.

GW FISHWHEELS (TEST FISHERY - 15TH YEAR): FISHWHEELS 1 AND 2 WERE STARTED ON 5 JUNE FOR TAGGING AND HISTORICAL CATCH INDEX ASSESSMENTS FOR SALMON AND STEELHEAD. FISHWHEELS 1 AND 2 ARE OPERATING WELL AT JUST BELOW AVERAGE WATER LEVEL FOR DATE. AVERAGE WATER LEVEL FROM 1992 TO 2007 WAS 2.4 M FOR DATE. ALL FISH THAT HAVE BEEN CAUGHT IN THE GITWINKSIHLKW FISHWHEELS HAVE BEEN RELEASED.

GREASE HARBOUR FISHWHEELS: THREE FISHWHEELS WILL OPERATE AT GREASE HARBOUR IN 2008 FOR IN-SEASON MARK RECAPTURE TAG RECOVERIES. THE FISHWHEEL STARTUP DATES WERE: 11 JUNE (FW5), 12 JUNE (FW6) AND 13 JUNE (FW3). ALL THREE FISHWHEELS ARE OPERATIONAL. ALL FISH CAUGHT IN THE GREASE HARBOUR FISHWHEELS HAVE BEEN RELEASED.

SINCE ONLY THREE FISHWHEELS ARE FISHING AT GREASE HARBOUR COMPARED TO FOUR SINCE 2000, TOTAL FISHWHEEL CATCHES IN 2008 AS REPORTED BELOW WILL NOT BE DIRECTLY COMPARABLE WITH FISHWHEEL CATCH AVERAGES FROM 2000 TO 2007. CATCH AVERAGE COMPARISONS AT THE GW FISHWHEELS WILL BE COMPARABLE AND ARE PROVIDED ONCE A WEEK AS WEEK ENDING COMPARISONS ON MONDAYS IN THE ATTACHMENT.

NASS SOCKEYE SALMON:
THE NASS SOCKEYE RUN SIZE ESTIMATE TO GITWINKSIHLKW TO DATE (159,185) IS CURRENTLY TRACKING BELOW AVERAGE (179,000) RETURN BASED ON A MEAN RUN SIZE TO GITWINKSIHLKW OF 281,000 FROM 1994 TO 2007.

THE RUN SIZE ESTIMATE IS A COMBINATION OF MARK-RECAPTURE AND HISTORICAL CATCH INDICES METHODS. NOTE THAT MARK RECAPTURE ESTIMATES WILL CHANGE OVER A 5 DAY PERIOD DUE TO MARK RATES STABILIZING AT GREASE HARBOUR AS FISH TAGGED AT GITWINKSIHLKW PASS THE UPSTREAM GREASE HARBOUR FISHWHEEL SITES OVER A 5 DAY PERIOD. AFTER THE MARK RATE STABILIZES, THE DAILY ESTIMATE IS BETTER AT PREDICTING ACTUAL CATCH EFFICIENCIES AT THE GW FISHWHEELS THAN THE HISTORICAL INDICES. AS SUCH WE WILL USE HISTORICAL CATCH EFFICIENCIES DURING THE 5 D FLUCTUATING PERIOD WHILE MARK RECAPTURE ESTIMATES ARE STABILIZING FOR LESS FLUCTUATING ESTIMATES THAT ARE REPORTED. CURRENTLY, MARK RECAPTURE ESTIMATES ARE FINAL TO 22 JULY AND LATER DATES WILL FLUCTUATE FROM 23 JULY TO 1 AUGUST AS ADDITIONAL CATCH AND TAG RECOVERY DATA BECOME AVAILABLE FROM THE GH FISHWHEELS.

THE RUN SIZE TARGET FOR NASS SOCKEYE TO GITWINKSIHLKW IS 225,000 TO 250,000 DEPENDING ON HARVESTS PROJECTED ABOVE GITWINKSIHLKW. NISGA'A FISHERIES IS ESTIMATING THAT APPROXIMATELY 62% (93-07 MEDIAN) OF THE SOCKEYE RUN HAS PASSED GITWINKSIHLKW TO DATE. USING FINAL MARK-RECAPTURE ESTIMATES TO 22 JULY, CURRENT FORECAST METHODS ARE PREDICTING A GOOD PROBABILITY OF REACHING THE RUN SIZE TARGET TO GW (225,000) WITH ESTIMATES RANGING FROM 272,000 (MEAN RUN TIMING METHOD - RANGE 247,000-297,000) TO 276,000 (IN-SEASON TO FINAL METHOD).

THE NET ESCAPEMENT ESTIMATE FOR NASS SOCKEYE TO DATE IS 149,417. THE NET ESCAPEMENT TARGET IS 200,000 (160,000 TO MEZIADIN RIVER AND 40,000 TO NON-MEZIADIN SYSTEMS).

MEZIADIN FISHWAY OPENED ON 1 JULY FOR ESCAPEMENT COUNTS TO RIVER. TOTAL COUNTS OF SOCKEYE AT MEZIADIN TO 27 JULY ARE: 72,404 ADULTS (2637 TAGS) AND 182 JACKS. THE 2008 CUMULATIVE ADULT COUNT (72,404) TO DATE IS ABOVE AVERAGE (59,000) BASED ON MEAN COUNTS AT THE MEZIADIN FISHWAY FROM 1994 TO 2007. THE AVERAGE COUNT OF ADULT SOCKEYE FROM 1994 TO 2007 WAS 170,000. THE PRELIMINARY FISHWHEEL MEAN-RUN TIMING FORECAST IS PREDICTING ~170,000 (RANGE: 137,000-227,000) TO REACH THE FISHWAY BASED ON CURRENT ESCAPEMENT PASSED GW AND AVERAGE STOCK PROPORTION. OTHER FORECAST METHODS RANGE FROM 184,000 (IN-SEASON TO FINAL MEZIADIN COUNT METHOD) TO 194,000 (MEZIADIN MEAN RUN TIMING METHOD). NISGA'A FISHERIES IS ESTIMATING THAT ~37% OF THE MEZIADIN SOCKEYE RUN HAS REACHED THE FISHWAY TO DATE BASED ON MEAN COUNTS FROM 1990 TO 2007.

NISGA'A FISHERIES IS CURRENTLY USING A PRELIMINARY TOTAL RETURN TO CANADA (TRTC) ESTIMATE FOR NASS SOCKEYE OF BETWEEN 350,000 (PRE-SEASON) AND 406,000 (IN-SEASON) FOR TRACKING THE NISGA'A ENTITLEMENT OF NASS SOCKEYE THAT IS CURRENTLY RANGING BETWEEN 52,000 AND 65,000. THE 2008 TRTC ESTIMATES ARE FORECASTING BELOW AVERAGE (666,000) BASED ON TRTC RETURNS FROM 1994 TO 2007. TRTC RETURNS WILL BE INFLUENCED BY ALASKAN CATCHES WHICH ARE CURRENTLY BELOW AVERAGE TO DATE (SEE BELOW).

THE TOTAL NISGA'A CATCH ESTIMATE OF NASS SOCKEYE TO DATE IS 38,967. THIS TOTAL INCLUDES FSC CATCH (23,628) TO WEEK ENDING 19 JULY AND INDIVIDUAL MARINE SALE FISHERY CATCH ESTIMATES TO DATE (15,339). THE TOTAL CUMULATIVE AVERAGE NISGA'A FSC HARVEST FOR THE SAME WEEK ENDING PERIOD OF NASS SOCKEYE FROM 2000 TO 2007 WAS 16,500. THE ANNUAL TOTAL AVERAGE NISGA'A FSC HARVEST FROM 2000 TO 2007 OF NASS SOCKEYE WAS 26,000. THE NEXT NISGA'A CATCH ESTIMATE FOR WEEK ENDING 26 JULY WILL BE UPDATED ON WEDNESDAY, 30 JULY.

NISGA'A FOOD FISH (FSC) HARVESTING IS OPEN FOR ALL SPECIES AND IS ANTICIPATED TO REACH 35,000 SOCKEYE IN 2008. GIVEN THAT TOTAL FSC AMOUNTS ARE NOT EXPECTED TO EXCEED THE TOTAL NISGA'A ENTITLEMENT ESTIMATE FOR 2008, THE REMAINING ENTITLEMENT (~20,000 TO 30,000) WILL BE AVAILABLE FOR SALE FISHERIES. THEREFORE THE DIRECTOR OF NISGA'A FISHERIES AND WILDLIFE HAS OPENED THE NISGA'A MARINE INDIVIDUAL SALE FISHERY FOR HARVESTING NASS SOCKEYE AS A SALE FISHERY. IN-RIVER SALE FISHERIES ARE CLOSED AND ARE NOT EXPECTED TO OPEN IN 2008. NO HARVESTING FROM THE FISHWHEELS WILL OCCUR IN 2008. ALL FISH ARE BEING RELEASED FROM THE FISHWHEELS.

THREE NISGA'A INDIVIDUAL SALE FISHERIES HAVE OCCURRED TO DATE (16-17 JULY [17 BOATS]; 17-18 JULY [17 BOATS]; 23-25 JULY [17 BOATS]) IN AREA 3-12. TOTAL CATCHES IN THE NISGA'A MARINE SALE FISHERIES TO 28 JULY ARE: 15,339 SOCKEYE, 1,799 PINK, 269 COHO AND 178 CHUM.

THE NEXT NISGA'A MARINE SALE FISHERY IS SCHEDULED FOR A 48 HOUR OPENING FROM WEDNESDAY, 30 JULY (OPENS 6 PM) TO FRIDAY 1 AUGUST (CLOSES 6 PM).

THE NISGA'A NATION PASSED A RESOLUTION AT THE SPECIAL ASSEMBLY IN MAY 2008 RECOMMENDING THE CLOSURE OF THE GENERAL COMMERCIAL FISHERY IN AREA 3-12 DUE TO PRE-SEASON CONSERVATION CONCERNS OF NASS SOCKEYE AND CHINOOK. DFO KEPT AREA 3-12 CLOSED TO 20 JULY DUE TO THE POOR RETURN OF CHINOOK AND ENSURING GOOD ESCAPEMENT OF NASS SOCKEYE INTO THE RIVER. DFO OPENED AREA 3-12 TO THE GENERAL COMMERCIAL FISHERY STARTING ON 21 JULY WITH THE MAJORITY OF NASS CHINOOK THROUGH THE MARINE WATERS AND THE NASS SOCKEYE RUN CURRENTLY ON TRACK TO REACH THE ESCAPEMENT GOAL.

AREA 3 IS CURRENTLY CLOSED TO THE GENERAL COMMERCIAL FISHERY. LAST OPENING WAS FOR GILLNET ON SUNDAY 27 JULY IN WHICH 33 BOATS PARTICIPATED. CATCHES REPORTED WERE: 1393 SOCKEYE, 3336 PINKS, 1539 CHUM AND 3 CHINOOK. NO ANNOUNCEMENT HAS BEEN MADE BY DFO FOR THE NEXT GENERAL COMMERCIAL FISHERY. AREA 3 FISHERIES CONDUCTED TO 24 JULY HAVE BEEN 7 GILLNET [24 JUNE (170 BOATS), 1 JULY (209 BOATS), 7 JULY (174 BOATS), 14 JULY (179 BOATS), 15 JULY (5 BOATS), 21 JULY (16) AND 27 JULY (33)] AND 3 SEINE (14 JULY (13 BOATS), 15 JULY (5 BOATS) AND 21 JULY (13 BOATS)) FISHERIES. TOTAL COMMERCIAL HARVEST ESTIMATES IN AREA 3 TO 28 JULY ARE: 33,830 SOCKEYE, 11,682 PINK, 13,881 CHUM AND 396 CHINOOK (SOURCE OF DATA IS FROM DFO PRINCE RUPERT FISHERIES MANAGEMENT).

ALASKA GILLNET FISHERIES IN DISTRICTS 101 (TREE POINT) AND 106 (SUMNER AND UPPER CLARENCE) BEGAN ON 15 JUNE AND 8 JUNE, RESPECTIVELY. ALASKAN SEINE FISHERIES IN DISTRICTS 101 TO 104 TYPICALLY START IN ALASKAN WEEK'S 25 (15-21 JUNE; DISTRICT 102), WEEK 27 (29 JUNE - 5 JULY; DISTRICTS 101 AND 104) AND WEEK 29 (13-19 JULY; DISTRICT 103). SEINE FISHERIES OPENING DATES TO DATE ARE: DISTRICTS 101 (LOWER CLARENCE/REVILLA; OPENED ON 6 JULY), 102 (MIDDLE CLARENCE; OPENED ON 22 JUNE), 103 (CORDOVA; OPENED 24 JULY) AND 104 (NOYES/DALL; OPENED ON 6 JULY).

NOTE THAT ALASKAN SEINE FISHERIES IN DISTRICTS 101 AND 102 ARE CURRENTLY CLOSED BUT DISTRICTS 103 AND 104 WERE OPEN FOR A 14 HOUR FISHERY ON 27 JULY.

TOTAL IN-SEASON CATCH ESTIMATE OF SOCKEYE IN SOUTHEAST ALASKAN FISHERIES IS 67,726 BASED ON DATA TO 28 JULY ON THE ADFG WEBSITE AND IS COMPLETE CATCH REPORTING FOR WEEK 30 (ENDED 26 JULY). REPORTED CATCHES ARE WELL BELOW AVERAGE TO DATE. AVERAGE CATCH OF SOCKEYE IN SOUTHEAST ALASKAN FISHERIES IS 714,000 SOCKEYE FROM 1999 TO 2007. OF THE TOTAL ALASKAN CATCH OF SOCKEYE, NISGA'A FISHERIES IS ESTIMATING APPROXIMATELY 25,000 ARE NASS SOCKEYE BASED ON AVERAGE STOCK % DATA (1982-98) AND IS BELOW AVERAGE TO DATE. AVERAGE CATCH OF NASS SOCKEYE IS 165,000 FROM 1999 TO 2007.

NASS CHINOOK SALMON:
THE NASS CHINOOK RUN SIZE ESTIMATE TO GITWINKSIHLKW (13,579) IS TRACKING BELOW AVERAGE TO DATE (21,000) BASED ON A MEAN RUN SIZE TO GITWINKSIHLKW OF 22,000 FROM 1994 TO 2007. THE RUN SIZE TARGET FOR NASS CHINOOK TO GITWINKSIHLKW IS 17,000 DEPENDING ON HARVESTS PROJECTED ABOVE GITWINKSIHLKW. THE IN-SEASON TRACKING OF THE NASS CHINOOK RUN TO GITWINKSIHLKW IS PREDICTING 14,000 [MEAN RUN TIMING METHOD [RANGE 14,000-15,000] AND IN-SEASON TO FINAL METHOD] AS THE FINAL IN-SEASON RUN SIZE TOTAL TO GITWINKSIHLKW. THE 2008 RETURN TO DATE IS THE THIRD WORST ON RECORD SINCE THE START OF THE NISGA'A FISHERIES PROGRAM IN 1992. NISGA'A FISHERIES IS ESTIMATING THAT 97% (93-07 MEDIAN) OF THE RUN HAS PASSED GITWINKSIHLKW TO DATE. THE NET ESCAPEMENT ESTIMATE FOR NASS CHINOOK IS 12,459. THE NET ESCAPEMENT TARGET FOR NASS CHINOOK ABOVE GREASE HARBOUR IS 15,000.

TOTAL COUNTS OF CHINOOK AT MEZIADIN FISHWAY TO DATE ARE: 232 ADULTS (4 TAGS) AND 13 JACKS. THE 2008 CUMULATIVE ADULT COUNT (232) TO DATE IS ABOVE AVERAGE (110) BASED ON MEAN COUNTS AT THE MEZIADIN FISHWAY FROM 1994 TO 2007. THE AVERAGE COUNT OF ADULT CHINOOK AT MEZIADIN FISHWAY FROM 1994 TO 2007 WAS 480. THE PRELIMINARY FISHWHEEL MEAN-RUN TIMING FORECAST IS PREDICTING 320 CHINOOK (RANGE: 70-690) TO REACH THE FISHWAY BASED ON CURRENT ESCAPEMENT PASSED GW AND ESTIMATED STOCK COMPOSITION. OTHER FORECASTS RANGE BETWEEN 600 (IN-SEASON TO FINAL MEZIADIN COUNT METHOD) AND 900 (MEZIADIN MEAN RUN TIMING METHOD). NISGA'A FISHERIES IS ESTIMATING THAT ~26% OF THE MEZIADIN CHINOOK RUN HAS PASSED THE FISHWAY TO DATE BASED ON MEAN COUNTS FROM 1990 TO 2007. MARK-RECAPTURE SURVEYS FOR FINAL ESCAPEMENT ESTIMATES ARE ALSO PLANNED AT KWINAGEESE AND DAMDOCHAX RIVERS IN SEPTEMBER 2008.

THE KINCOLITH VIDEO-COUNTING FENCE BEGAN OPERATION ON 11 JUNE FOR COLLECTING ESCAPEMENT DATA FOR THE KINCOLITH RIVER AND PROVIDING AN INDEX OF ESCAPEMENT TO COASTAL STREAMS IN AREA 3. NET UPSTREAM COUNTS AT THE WEIR TO 26 JULY ARE: 774 CHINOOK (158 AFC AND 27 BROODSTOCK), 19 PINK AND 1 CHUM. OTHER WEIR COUNTS TO DATE ARE: 16 STEELHEAD (8 DOWN AND 8 UP). THE CURRENT COUNT OF CHINOOK PASSING THE WEIR IS ABOVE THE AVERAGE COUNT (635) FOR THE DATE FROM PAST OPERATIONS (2001, 2002, 2005-2007). NISGA'A FISHERIES PROJECTED THAT THE ESCAPEMENT GOAL (700) WOULD BE REACHED IN 2008 BASED ON THE RUN SIZE FORECAST METHOD WHICH IS CURRENTLY ESTIMATING ~1,500 (RANGE 737-2400) FROM MEAN RUN TIMING FROM PAST OPERATIONS (2001, 2002, 2005-2007). NISGA'A FISHERIES IS ESTIMATING THAT ~49% OF THE KINCOLITH CHINOOK RUN HAS PASSED THE WEIR TO DATE BASED ON THE RECONSTRUCTED MEAN RUN TIMING.

NISGA'A FISHERIES IS USING A PRELIMINARY TRTC ESTIMATE FOR NASS CHINOOK OF BETWEEN 20,000 (IN-SEASON) AND 21,000 (PRE-SEASON) FOR TRACKING THE NISGA'A ENTITLEMENT OF NASS CHINOOK. THE 2008 TRTC ESTIMATES ARE FORECASTING BELOW AVERAGE (36,000) BASED ON TRTC RETURNS FROM 1994 TO 2007. UNCERTAINTY OF MARINE COMMERCIAL AND RECREATIONAL CATCHES OF NASS CHINOOK MAKE IT DIFFICULT TO ACCURATELY ESTIMATE IN-SEASON TRTC ESTIMATES FOR NASS CHINOOK. HOWEVER, BASED ON THE IN-SEASON TRTC ESTIMATES FOR 2008, THE NISGA'A ENTITLEMENT OF NASS CHINOOK IS ~4,000. A CUMULATIVE UNDERAGE OF 3300 FROM PAST YEAR'S MANAGEMENT UNCERTAINTY MAY BE NEEDED TO FULFILL NISGA'A FSC NEEDS IN 2008 WHICH ON AVERAGE TOTAL 6200 NASS CHINOOK. AS A RESULT OF FSC REQUIREMENTS, THE ENTITLEMENT TARGET IS EXPECTED TO RANGE BETWEEN 4000 AND 7300 DEPENDING ON IN-SEASON RUN SIZE ESTIMATES DURING THE SEASON.

THE NISGA'A CATCH ESTIMATE OF NASS CHINOOK TO WEEK ENDING 19 JULY IS 3921 AND BELOW AVERAGE (00-07) FOR THE PERIOD. THE TOTAL AVERAGE NISGA'A FSC HARVEST OF NASS CHINOOK FROM 2000 TO 2007 FOR THE SAME WEEK ENDING PERIOD WAS 5800. THE ANNUAL TOTAL AVERAGE NISGA'A FSC HARVEST OF NASS CHINOOK FROM 2000 TO 2007 WAS 6200. THE NEXT NISGA'A CATCH ESTIMATE FOR WEEK ENDING 26 JULY WILL BE UPDATED ON WEDNESDAY, 30 JULY. THE UPDATED FSC NUMBERS WILL INCLUDE ANY HARVESTS IN THE NISGA'A MARINE FISHERIES. NO CHINOOK WERE PERMITTED FOR SALE IN ANY INDIVIDUAL SALE FISHERIES IN 2008.

NASS COHO SALMON:
THE NASS COHO RUN SIZE ESTIMATE TO GITWINKSIHLKW (2795) IS TRACKING ABOVE AVERAGE TO DATE (1200) BASED ON A MEAN RUN SIZE TO GITWINKSIHLKW OF 76,000 FROM 1994 TO 2007. THE RUN SIZE TARGET FOR NASS COHO TO GITWINKSIHLKW IS ~50,000 DEPENDING ON HARVESTS PROJECTED ABOVE GITWINKSIHLKW. NISGA'A FISHERIES IS ESTIMATING THAT ~2% (93-07 MEDIAN) OF THE RUN HAS PASSED GITWINKSIHLKW TO DATE. THE NET ESCAPEMENT ESTIMATE FOR NASS COHO IS 2795. THE NET ESCAPEMENT TARGET FOR NASS CHINOOK ABOVE GREASE HARBOUR IS ~41,000.

TOTAL COUNTS OF COHO AT MEZIADIN FISHWAY TO DATE ARE: 0 ADULTS (0 TAGS) AND 0 JACKS. THE 2008 CUMULATIVE ADULT COUNT (0) TO DATE IS THE SAME AS THE AVERAGE (0) BASED ON MEAN COUNTS AT THE MEZIADIN FISHWAY FROM 1994 TO 2007. THE AVERAGE COUNT OF ADULT COHO AT MEZIADIN FISHWAY FROM 1994 TO 2007 WAS 3600. COHO BEGIN PASSING THE FISHWAY IN EARLY AUGUST.

NISGA'A FISHERIES IS USING A PRELIMINARY TRTC ESTIMATE FOR NASS COHO OF BETWEEN 104,000 (IN-SEASON) AND 173,000 (PRE-SEASON - EARLY INTO RUN) FOR TRACKING THE NISGA'A ENTITLEMENT OF NASS COHO THAT IS CURRENTLY RANGING BETWEEN 8,000 AND 13,800. THE 2008 PRE-SEASON TRTC ESTIMATE IS FORECASTED FOR A BELOW AVERAGE (162,000) RETURN BASED ON TRTC RETURNS FROM 1994 TO 2007.

THE TOTAL NISGA'A CATCH ESTIMATE OF NASS COHO TO DATE IS 291. THIS TOTAL INCLUDES FSC CATCH (22) TO WEEK ENDING 19 JULY AND INDIVIDUAL MARINE SALE FISHERY CATCH ESTIMATE TO DATE (269). THE NEXT NISGA'A FSC CATCH ESTIMATE FOR WEEK ENDING 26 JULY WILL BE UPDATED ON WEDNESDAY, 30 JULY.

NASS PINK SALMON:
THE FISHWHEEL CATCH OF PINK SALMON (145) TO DATE IS WELL BELOW THE MEAN CATCH (1100) FOR EVEN YEAR RETURNS FROM 2000 TO 2007.

NISGA'A FISHERIES IS CURRENTLY USING THE PRE-SEASON TRTC ESTIMATE FOR NASS PINKS OF 569,000 FOR TRACKING THE NISGA'A ENTITLEMENT (54,000) OF NASS PINK. THE 2008 TRTC ESTIMATE IS FORECASTING ABOVE AVERAGE (524,000) BASED ON TRTC RETURNS OF EVEN YEAR PINKS FROM 1994 TO 2007. HOWEVER, THE LAST NASS PINK SALMON EVEN RETURN YEAR (2006) WAS EXTREMELY LOW (230,000) AND CURRENT COMMERCIAL CATCHES OF PINK HAVE BEEN LOW.

THE TOTAL NISGA'A CATCH ESTIMATE OF NASS PINK TO DATE IS 2137. THIS TOTAL INCLUDES FSC CATCH (338) TO WEEK ENDING 19 JULY AND INDIVIDUAL MARINE SALE FISHERY CATCH ESTIMATE TO DATE (1799). THE NEXT NISGA'A CATCH ESTIMATE FOR WEEK ENDING 26 JULY WILL BE UPDATED ON WEDNESDAY, 30 JULY.

THE TOTAL NISGA'A CATCH ESTIMATE OF NASS CHUM TO DATE IS 302. THE TOTAL INCLUDES FSC CATCH (124) TO WEEK ENDING 19 JULY AND INDIVIDUAL MARINE SALE FISHERY CATCH ESTIMATE TO DATE (178). THE NEXT NISGA'A CATCH ESTIMATE FOR WEEK ENDING 26 JULY WILL BE UPDATED ON WEDNESDAY, 30 JULY.

NASS SUMMER-RUN STEELHEAD:
THE FISHWHEEL CATCH OF STEELHEAD (34) TO DATE IS ABOVE AVERAGE CATCH LEVEL (17) FROM 2000-2007. BASED ON EARLY FISHWHEEL CATCH DATA, THE NASS SUMMER RUN STEELHEAD ESTIMATE TO GITWINKSIHLKW (456) IS TRACKING ABOVE AVERAGE (225) TO DATE BASED ON A MEAN RUN SIZE TO GITWINKSIHLKW OF 7,800 DURING FISHWHEEL OPERATIONS FROM 1994 TO 2007 (BASED ON PRELIMINARY HISTORICAL RUN SIZE DATA). THE PRELIMINARY RUN SIZE TARGET FOR NASS STEELHEAD TO GITWINKSIHLKW IS 4,200 DEPENDING ON ANY HARVESTS PROJECTED ABOVE GITWINKSIHLKW.

TOTAL COUNTS OF STEELHEAD AT MEZIADIN FISHWAY TO DATE ARE: 0 ADULTS (0 TAGS). THE 2008 CUMULATIVE ADULT COUNT (0) TO DATE IS THE SAME AS THE AVERAGE (0) BASED ON MEAN COUNTS AT THE MEZIADIN FISHWAY FROM 1994 TO 2007. THE AVERAGE COUNT OF STEELHEAD DURING OPERATION OF MEZIADIN FISHWAY FROM 1994 TO 2007 WAS 50. STEELHEAD BEGIN PASSING THE FISHWAY IN LATE AUGUST.

THE NISGA'A CATCH ESTIMATE OF NASS STEELHEAD TO WEEK ENDING 19 JULY IS 33.
